Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth to illustrate, but are not to be construed to limit the scope of the invention.

Referring to fig. 5, an exemplary network topology connection diagram of a target route estimation system is provided, a server 10 of the target route estimation system provided by the present invention can be connected to a plurality of clients 20 via the internet, and an exemplary communication link establishment method is provided below.

The user terminal 20 firstly sends an internet access request to the internet access gateway 30, the internet access gateway 30 sends the access request to the internet service gateway 40, and the internet service gateway 40 authenticates the access request. And when the authentication is successful, sending a message of successful authentication to the internet access gateway 30, and establishing a network communication transmission channel with the internet access gateway 30. The internet access gateway 30 sends the successful authentication message to the user terminal 20, and after receiving the successful authentication message, the user terminal 20 establishes a communication link with the server terminal 10 for data transmission.

Some possible embodiments of the present invention are explained below based on the above network structure.

As shown in fig. 1, a schematic flow chart is provided for an embodiment of a target route estimation method according to the present invention, the target route estimation method is suitable for data estimation of a new route and a route with data missing in an air route or an air route in a stopped flight, and the estimation method includes:

and S1, the user side generates a target route according to the target starting airport and the target arrival airport which are input by the user, generates a measurement and calculation request according to the target measurement and calculation data which are input by the user, and sends the target route and the measurement and calculation request to the server.

It should be noted that the target measurement and calculation data may be selected according to the measurement and calculation requirements of the user, and may include: passenger deviation value, range, flight duration, posted direct freight rate, average discount, etc. The user side can be electronic equipment such as a computer, a mobile phone and the like generally, and when the user side performs data interaction with the server, the user side can package information such as own equipment identification codes, timestamps, data contents and the like into data frames and send the data frames to the server, so that the target airline and target measurement and calculation data needing to be measured and calculated can be used as data contents and transmitted to the server after being packaged.

S2, the server determines an alternative airport according to a target originating airport or a target arriving airport, selects a reference airport from the alternative airports according to a first preset screening condition, and generates a reference route according to the reference airport when the reference airport is successfully screened out; and when the reference airport is not successfully screened out, generating a virtual reference airport according to the target starting airport or the target arrival airport, and generating a reference route according to the virtual reference airport.

Preferably, the alternative airport may be determined first from the target origin airport, and if there is no alternative airport or there is no satisfactory reference airport in the alternative airport, the reference airport may be re-determined again from the target arrival airport. The target origin airport or target arrival airport may also be randomly selected to determine alternate airports.

It should be understood that the method for selecting the alternative airport may be set according to actual requirements, and since the reference airline has the same origin airport or arrival airport as the target airline and the alternative airport has a certain relevance and similarity with the target origin airport or target arrival airport as the basis for selection, the reference airline generated by the reference airport may be used as the basis for calculation.

For example, it may be assumed that the target origin airport is a shenzhen airport, the target arrival airport is an shanghai airport, and the candidate airports, guanzhou airport, zhhai airport and foidan airport are determined according to the shenzhen airport, then the guanzhou airport screened from these candidate airports may be used as the origin airport of the reference airline, the shanghai airport may be used as the arrival airport of the reference airline, then the target airline to be measured is shenzhen-shanghai, the reference airline according to which the measurement is measured is guanzhou-shanghai, two airlines have the same airport, i.e., shanghai airport, and the guanzhou airport is a reference airport of the shenzhen airport, and both have certain relevance and similarity in terms of passenger throughput, airport level, city scale and development situation.

For another example, it may be further assumed that the target origin airport is a Shenzhen airport, the target arrival airport is a Shanghai airport, and the alternative airports including the Hangzhou airport, the Nanjing airport and the Wuxi airport are determined according to the Shanghai airport, so that the state airport screened from the alternative airports can be used as the arrival airport of the reference airline, the Shenzhen airport can be used as the origin airport of the reference airline, the target airline required to be measured is Shenzhen-Shanghai, the reference airline used as the basis for the measurement is Shenzhen-Hangzhou, and the two airlines have the same airport, that is, the Shenzhen airport.

It should be understood that the specific selection method of the alternative airports may be set according to actual needs, for example, the target origin airport may be used as a center, all airports within a certain range may be used as the alternative airports, for example, an airport rank may also be used as a basis for selection, and an airport having the same airport rank as the target origin airport may be used as the alternative airport, for example, multiple bases for selection may also be combined, such as an airport within a certain range and having the same airport rank as the target origin airport may be used as the alternative airport, and those skilled in the art may also select other alternative airport determination manners according to actual needs, which is not described herein again.

Because the reference route is the basis for measuring and calculating the target route, the selection of the reference airport should be as close as possible to the target origin airport or the target arrival airport in the aspects of passenger throughput, airport level, city scale, development situation and the like.

For example, the passenger throughput may be used as the screening condition, and the candidate airport selected by the target origin airport may be used as the reference airport, and the candidate airport having the smallest difference between the passenger throughput of the candidate airport and the passenger throughput of the target origin airport may be used as the reference airport. For another example, the airport rank may be used as the screening condition, and an alternative airport selected by the target origin airport may be used as the reference airport, and an alternative airport having the same airport rank as the target origin airport may be used as the reference airport. Those skilled in the art can also select other alternative airport determination manners and reference airport screening manners for the purpose of improving the measurement and calculation accuracy, which are understood to be included in the protection scope of the present invention and will not be described in detail herein.

It should be understood that the determination of the virtual reference airport may be performed in the same manner as the selection of the alternative airport, in which the virtual reference airport is determined according to the target origin airport, and if the virtual reference airport that meets the requirement cannot be generated, the virtual reference airport may be re-determined according to the target arrival airport. The target origin airport or target arrival airport may also be randomly selected to determine the virtual reference airport.

Several virtual reference airport selection methods that may be implemented are presented below. Taking the target originating airport as an example, several airports close to the target originating airport within a certain range and centered on the target originating airport may be selected, and the average value of the parameters of these airports is taken as the virtual reference airport. The parameters for an airport may be airport rating, airport throughput, distance from the target originating airport, etc.

And S3, the server judges the type of the target measurement and calculation data according to the measurement and calculation request, calls a preset measurement and calculation program according to the judgment result, measures and calculates the target air route according to the measurement and calculation program and the reference air route, obtains the measurement and calculation result and sends the measurement and calculation result to the user side.

It should be noted that the type of the target measured data can be divided by the relation with the distance, some measured data are directly related to the distance of the air route and can be directly determined according to the linear distance of the air route, such as the air distance, the flight time, the direct arrival price and the like, and since the linear distance between the target air route and the reference air route is known, the measured data can be directly measured and obtained by the relation of the linear distance between the target air route and the reference air route, and therefore, a measuring and calculating program can be directly called to measure and calculate.

However, some measured data are not directly related to the distance of the airline and cannot be directly determined according to the linear distance of the airline, for example, average class passenger volume, average class passenger seat rate, average class revenue, seat and kilometer income, average discount and the like, and the measured modes of the measured data are not completely the same, so that a preset measurement model can be called through a measurement program, and corresponding airline data of a reference airline can be input into the measurement model for measurement.

The type of the target measurement and calculation data is judged, different measurement and calculation programs are called for measurement and calculation, the measurement and calculation data directly related to the distance between the air routes can be directly calculated, and the measurement and calculation data not directly related to the distance between the air routes is measured and calculated through the measurement and calculation programs, so that the measurement and calculation speed can be increased, the measurement and calculation of different types of measurement and calculation data can be realized, and the measurement and calculation accuracy is further improved.

And S4, the user side receives and displays the measuring and calculating result.

It should be understood that the measurement result is target measurement data requested by the user terminal, and the displayed data is determined according to which target measurement data is requested by the user, for example, if the target measurement data of the airlines a-B requested by the user through the user terminal are range, flight time, average flight volume and average revenue, the user terminal can display that "the range of the target airlines a-B is x, the flight time is x, the average flight volume is x, and the average revenue is x" after receiving the measurement result returned by the server.

Wherein the reference route has the same origin or arrival airport as the target route.

The method determines available alternative airports according to a target origin airport or a target arrival airport input by a user, then screens the alternative airports according to preset screening conditions, selects an airport closest to the target origin airport or the target arrival airport from the selected airports, generates a reference air route having a common airport with a target air route according to the selected airport, can ensure the maximum similarity between the reference air route and the target air route, and generates a virtual reference airport under the condition of missing the reference airport, thereby effectively solving the problems of measurement failure and accuracy reduction caused by the lack of the reference air route meeting the requirement of similarity with the target air route, then measures and calculates the target air route according to the data of the reference air route, expands the available amount of the data, is suitable for measuring and calculating the new air route and the air route with missing data, and depends on the similarity between the reference air route and the target air route, compared with the traditional measuring and calculating mode, the accuracy and precision of the air route measuring and calculating can be further improved, and therefore a more reliable basis is provided for operation decision of the air route.

Optionally, in some possible implementations, the server determines an alternative airport according to the target originating airport or the target arriving airport, selects a reference airport from the alternative airports according to a first preset screening condition, and generates a reference route according to the reference airport when the reference airport is successfully screened, specifically including:

the server defines a first screening range by taking a target starting airport as a circle center and a first preset distance as a radius, all airports except the target starting airport in the first screening range are used as alternative airports, a reference airport meeting requirements is selected from the alternative airports according to a first preset screening condition to be used as a starting airport, a target arrival airport is used as an arrival airport, and a reference route is generated;

when the reference airport which does not meet the requirement does not exist, the server uses the target arrival airport as a circle center and uses the first preset distance as a radius to define a new first screening range, all airports except the target arrival airport in the new first screening range are used as new alternative airports, the reference airport which meets the requirement is selected from the new alternative airports according to the first preset screening condition to be used as the arrival airport, and the target origin airport is used as an origin airport to generate a reference air route.

As shown in fig. 2, an exemplary illustration of an alternative airport screening scope is provided, where a target route is from Shenzhen to Shanghai, a target origin airport is Shenzhen, a target arrival airport is Shanghai, a preset distance is a, then a Shenzhen is used as a circle center, the circular range is the screening range, and as can be seen from the figure, besides the Shenzhen airport, there are A, B, C airports and D airports in the screening range, which are the candidate airports, then one of the four alternative airports A, B, C and D is selected as a reference airport according to the preset screening condition, because the alternative airport selected with Shenzhen as the center of circle is used, the selected reference airport is the originating airport of the reference airline, the arrival airport of the reference airline is the Shanghai airport, and the reference airline is from the airport D to the Shanghai airport if the selected alternative airport D is assumed.

If the A, B, C airport and D airport are not qualified after the screening of the preset screening condition, and the reference airport is not selected from the target origin airport at the moment, the screening range is determined by using the same method as the above step, if the screening range has E, F airports and G airports, the three airports of E, F airports and G are alternative airports, then the reference airport is selected from the three airports of E, F airports and G airport according to the same preset screening condition, the selected reference airport is the arrival airport of the reference airline, the origin airport of the reference airline is the Shenzhen airport, and the selected alternative airport is the Shenzhen airport F.

It should be understood that the preset screening condition may be set according to actual requirements, for example, it may be set to screen an airport substantially similar to a target origin airport or a target arrival airport, and the specific evaluation index may be set according to actual requirements, for example, it may include: airport level, throughput, number of flights on the fly, etc. Airports that are geographically close to the destination origin airport or the destination arrival airport, such as airports with a straight-line distance less than a predetermined distance, may also be screened.

Preferably, if no reference airport is determined by the target arrival airport, the screening range may be expanded by increasing the value of the preset distance, and the screening may be continued until at least one reference airport can be determined.

The method comprises the steps of defining a screening range by taking a target origin airport or a target arrival airport as the center of a circle, preferentially selecting a reference airport with a geographic position closer to an airport to be calculated compared with an alternative airport outside the screening range, ensuring the similarity of geographic factors of the reference airport and the target origin airport or the target arrival airport, reducing the influence of the geographic factors on measurement errors, improving the accuracy of measurement, determining the screening range of the alternative airport by using the target origin airport, and re-screening by using the target arrival airport when the reference airport is not determined, wherein the success rate of selecting the reference airport can be ensured, for example, if an effective alternative airport such as a Lhasa airport is lacked near some airports, and if only the Lhasa airport is taken as the selection reference of the alternative airport, effective alternatives cannot be obtained, the alternative airport can be determined only by expanding the screening range, so that the similarity between the alternative airport and the pizza airport is inevitably low, the measuring and calculating accuracy is greatly reduced, and when the target starting airport cannot determine a reasonable alternative airport, the target arrival airport determines the alternative airport, so that the screening range can be prevented from being expanded and the measuring and calculating accuracy is reduced when the alternative airport is lacked or a reference airport which meets the conditions is not available.

Optionally, in some possible implementations, selecting a reference airport that meets the requirement from the candidate airports as an originating airport according to a first preset screening condition specifically includes:

the server judges whether a route exists between the first alternative airport and a target arrival airport, judges whether route data of the route meet the data volume requirement when the route exists, and reserves the first alternative airport when the data volume requirement is met; removing the first alternative airport from all alternative airports when no airline exists or the data volume requirement is not met;

the server selects an alternative airport with the smallest difference with the throughput of the target originating airport from the rest of alternative airports as a reference airport, and takes the reference airport as the originating airport;

wherein the first alternative airport is any one of the alternative airports.

The data volume demand may be set according to the period of data to be measured, for example, if data of an airport all year around needs to be measured, the data volume needs to exceed 12 months in order to ensure the measurement accuracy.

An exemplary reference airport selection scheme is shown in fig. 3, and is described below in conjunction with the example shown in fig. 3.

It should be understood that although the originating airport and the destination airport are shown as parallel execution steps in fig. 3, in practical applications, one may be judged first, if there is no reference airport, and then the other, and the example given below screens the reference airport first through the originating airport, and if there is no reference airport, then through the destination airport.

First, find whether there is an airport in flight or a historic airline to the destination airport within 500 km of the originating airport,

then, judging whether the historical data of the air route meets the conditions, if the navigation predicts the annual data of the next year, the historical data amount needs to exceed 12 months, and if the navigation predicts the winter spring or the summer autumn, the historical data amount needs to meet the data amount of 1 winter spring or 1 summer autumn;

finally, selecting an airport with the minimum difference between the airport throughput and the originating airport throughput as a reference airport, preferentially selecting an airport within 300 kilometers and in the same province, and if not, selecting an airport with the linear distance of 300 kilometers being 500 kilometers;

if the reference airport which meets the requirements is not screened out through the screening conditions, the reference airport is screened out through the destination airport, the screening steps are the same as above, and if the reference airport which meets the conditions is not screened out through the starting airport and the destination airport, the reference airport is returned.

It should be noted that, because the distance correlation between the selection of the candidate airport and the originating airport or the arrival airport is high, on this basis, the airport with the smallest difference in throughput is selected as the reference airport, so that the maximum similarity between the reference airport and the airport to be measured can be ensured, and the measurement and calculation accuracy is improved.

Optionally, in some possible implementations, when the reference airport is not successfully screened out, generating a virtual reference airport according to the target origin airport or the target arrival airport, and generating a reference route according to the virtual reference airport, specifically including:

when the reference airport is not successfully screened out, the server uses the target originating airport as the center of a circle, uses a second preset distance as a radius to define a second screening range, determines a target administrative region to which the target originating airport belongs in the second screening range, uses all administrative regions except the target administrative region in the second screening range as alternative administrative regions, selects the alternative administrative regions meeting requirements from the alternative administrative regions according to second preset screening conditions as reference administrative regions, judges whether airports exist in each reference administrative region, eliminates the administrative regions without airports from the reference administrative regions, generates a virtual reference airport according to the information of the airports in each reference administrative region after elimination, uses the virtual reference airport as the originating airport, and uses the target arrival airport as the arrival airport to generate a reference route;

when all the reference administrative areas are removed, the server defines a new second screening range by taking a target arrival airport as a circle center and taking a second preset distance as a radius, determines a target administrative area to which the target arrival airport belongs within the new second screening range, takes all administrative areas except the target administrative area within the new second screening range as new alternative administrative areas, selects an alternative administrative area meeting requirements from the new alternative administrative areas as a new reference administrative area according to second preset screening conditions, judges whether an airport exists in each new reference administrative area, removes the administrative areas without the airports from the new reference administrative area, generates a new virtual reference airport according to the information of the airports in each reference administrative area after the removal processing, takes the new virtual airport as the arrival airport, and takes the target airport as an origination airport, and generating a reference route.

It should be understood that the preset screening condition may be set according to actual requirements, for example, the preset screening condition may be set to screen out an administrative area similar to the economic development situation of the administrative area where the target origin airport or the target arrival airport is located, and the specific evaluation index may be set according to actual requirements, for example, and may include: city comprehensive development index, per capita GDP or per capita income, and the like. Administrative regions that are close to the geographic location of the target origin airport or target arrival airport, such as administrative regions with a straight line distance less than a preset distance, may also be screened.

The administrative area may be province, city, or the like, and the information on the airport may include an airport level, throughput, number of flying lanes, a straight distance from the target origin airport or the target arrival airport, or the like.

The method for specifically generating the virtual reference airport may be set according to actual requirements, for example, the information of the airport in each reference administrative area after the elimination processing may be averaged to be used as the information of the virtual reference airport.

Taking the airport grade and the straight-line distance from the target starting airport as examples, assuming that after being eliminated, A, B, C, D airports are used for generating virtual reference airports, wherein the grade of the airport A is 1, and the distance from the target starting airport is 10 km; the grade of the airport B is 2, and the distance from the target starting airport is 200 km; the grade of the airport C is 1, and the distance from the target starting airport is 50 km; airport D has a rating of 1 and a distance of 40km from the target origin airport.

Then by taking the average the airport rating is 1.25, rounded to 1, and the average distance from the target originating airport is 75km, then the airport rating of the resulting virtual reference airport is 1 and the distance from the target originating airport is 75 km.

It should be understood that the parameters of more virtual reference airports may also be determined in the above manner, and are not described in detail.

The generation process of the virtual reference airport is explained below, assuming that the target airline is from Shenzhen to Shanghai, the target origin airport is Shenzhen, the target arrival airport is Shanghai, the preset distance is b, and the city is used as the administrative region.

Then, using Shenzhen as a circle center, and the circular range with the radius b as a screening range, assuming that 6 cities of Guangzhou, Huizhou, Zhuhai, Dongguan, Zhongshan and hong Kong are used as alternative administrative regions in the screening range except for the Shenzhen airport, then the preset screening condition can be a city similar to the economic development condition of Shenzhen, and specifically can be judged through some economic indexes and data, and the specific judgment rule can be set by those skilled in the art, and is not described herein again. Assuming that the economic development conditions of Guangzhou and hong Kong are similar to those of Shenzhen through screening, the reference administrative regions obtained after screening are the Guangzhou and the hong Kong, and the Guangzhou and the hong Kong have organic farms through judgment, the virtual reference airport can be generated according to the Guangzhou airport and the hong Kong airport.

The specific generation manner of the virtual reference airport has already been described in the previous embodiment, and is not described herein again.

If the screening of the preset screening conditions is carried out, 6 cities of Guangzhou, Huizhou, Zhuhai, Dongguan, Zhongshan and hong Kong do not meet the requirements, at this time, no reference administrative area is selected through the target originating airport, or no airport exists in the selected reference administrative area, the above sea is continuously used as the circle center, the screening range is determined according to the same method, if the screening range has three cities of Hangzhou, Nanjing and Suzhou, the three cities of Hangzhou, Nanjing and Suzhou are alternative administrative areas, then the reference administrative areas are selected from the three cities of Hangzhou, Nanjing and Suzhou according to the same preset screening conditions, the existence of an airport is judged, and then the virtual reference airport is generated according to the airport.

Preferably, if the reference administrative area is not determined by the arrival of the object at the airport, the screening range may be expanded by increasing the value of the preset distance, and the screening may be continued until at least one reference administrative area can be determined.

The virtual reference airport generated by the method can still ensure that the target airline can be measured and calculated under the condition that no reference airport exists, and the virtual reference airport is screened out according to the preset screening conditions, including the airport scale, airline conditions and the like, and has certain similarity with the target starting airport, so that the generated virtual reference airport can also be used as the basis for measuring and calculating the target airline, and has higher accuracy.

Optionally, in some possible implementation manners, selecting, according to a second preset screening condition, a candidate administrative area that meets the requirement from the candidate administrative areas as a reference administrative area specifically includes:

the server generates a target evaluation vector of a target administrative region and an alternative evaluation vector of each alternative administrative region according to preset evaluation indexes, calculates Euclidean distances between each alternative evaluation vector and the target evaluation vector respectively, selects a preset number of Euclidean distances from all the obtained Euclidean distances according to the sequence of numerical values from small to large, and takes the alternative administrative regions corresponding to the preset number of Euclidean distances as reference administrative regions.

It should be noted that the alternative evaluation vector can be set according to actual requirements, and can be used for evaluating the situations of economy, culture, infrastructure and the like between different administrative regions.

For example, taking an administrative region as a city as an example, the evaluation vector may include: average GDP, average monthly wages, city population, presence or absence of high-speed rail stations, national road number, airport number, industry type, and the like.

It should be understood that the partial evaluation vectors may differ in their numerical type, and thus, to facilitate the processing of the data, the data may be normalized and normalized collectively, and then the vectors may be generated.

For example, taking the city general population, the presence or absence of high-speed rail stations and the number of airports as examples, the city general population is larger in value, the presence or absence of high-speed rail stations can be represented by 1 and 0, wherein 1 represents the presence of high-speed rail stations, 0 represents the absence of high-speed rail stations, the number of airports is smaller, generally between 0 and 3, and then after normalization and standardization, the values of the city general population, the presence or absence of high-speed rail stations and the number of airports are respectively assumed to be x₁、x₂And x₃Then the evaluation vector of any one of the candidate administrative regions may be<x₁₁，x₁₂，x₁₃>The evaluation vector of the target administrative region may be<x₂₁，x₂₂，x₂₃>Then, the euclidean distance d between the candidate administrative region and the target administrative region can be calculated by the following formula₁₂。

Where n is the number of vectors in the evaluation vector.

Alternatively, the euclidean distance between vectors may also be calculated by the pdist function of Matlab.

The administrative regions are expressed in an evaluation vector mode, and then the Euclidean distance between the administrative regions and the evaluation vector of the target administrative region is calculated, so that the relevance between each alternative administrative region and the target administrative region can be accurately reflected, the reference administrative region which is closest to the target administrative region in the aspect of aviation is selected, indexes of various economic, cultural, basic settings and the like of the administrative regions are subjected to numerical processing, the method has the advantages of high processing speed and high matching precision, and the influence of various factors on airport navigation is comprehensively considered in the selected reference administrative region, so that the measuring and calculating result is more comprehensive and objective.

Optionally, in some possible implementation manners, the server determines the type of the target measurement and calculation data according to the measurement and calculation request, calls a preset measurement and calculation program according to the determination result, and measures and calculates the target route according to the measurement and calculation program and the reference route, including:

the server judges the type of the target measuring and calculating data according to the measuring and calculating request, if the type of the target measuring and calculating data is the first type of measuring and calculating data, a first measuring and calculating program is called to calculate the proportional relation between the linear distance of the target air route and the linear distance of the reference air route, and the target air route is measured and calculated according to the proportional relation and the air route data of the reference air route;

if the target route data are the second type of measurement and calculation data, calling a second measurement and calculation program to judge the stop types of the target route and the reference route, selecting a corresponding target measurement and calculation model from preset measurement and calculation models according to the stop types of the target route and the reference route, determining the target route data according to the target measurement and calculation model, inputting the target route data into the target measurement and calculation model, and measuring and calculating the target route;

the first type of measured and calculated data is measured and calculated data directly related to the linear distance of the air route, the second type of measured and calculated data is measured and calculated data indirectly related to the linear distance of the air route, and the target air route data comprises at least one of air route data of all air routes of a target starting airport, air route data of all air routes of a target arriving airport and air route data of a reference air route.

For example, the first type of reckoning data may include: at least one of line spacing, flight duration, and posted direct freight rate, and the second type of measured data may include: at least one of average class passenger volume, average class passenger seat rate, average class revenue, seat kilometer revenue and average discount.

An exemplary method of gauging of the above first and second types of gauging data is given below, wherein: measuring course straight line distance/reference course straight line distance

Measuring and calculating the flight time of the route straight line distance/reference route straight line distance and reference route flight time

Predicting the freight rate of the Y cabin, namely measuring and calculating the straight-line distance of the route/the straight-line distance of the reference route and the freight rate of the YB reference route

Average class passenger capacity as total number of people/round trip total class

Average class passenger seat rate is passenger seat rate accumulation/total class

Average discount accumulation/total shift

For the data such as average class revenue, seat kilometer revenue and the like, the average class passenger volume and the average class discount can be calculated and then calculated.

It should be understood that, for the first kind of measured data, it is related to the straight-line distance of the flight path, and the YB freight rate is given as an example below, and the measured data of the flight distance and the flight duration are the same and will not be described again.

For example, with Shenzhen to Yichang as the reference flight path and Shenzhen to Wushan as the target flight path, the relevant data are shown in Table 1:

TABLE 1

According to the measurement formula, the method can obtain the method from Shenzhen to Wushan:

range (one way) 1018/910 × 1032-1154 km

Duration of flight (round trip) 1154/1032 × 235 ═ 263 minutes

YB freight rate (one way) ═ 1154/1032 × 1100 ═ 1230 yuan

The YB freight rate is a direct freight rate published, and means that an airline company directly notes an air transportation price of freight from an origin airport to a destination airport on the freight rate.

It should be noted that, the stopping type of the airline is divided into a straight flight, a stopping long section and a stopping short section, wherein, the straight flight airline does not need to be described, the stopping long section refers to a route section from the departure place to the destination for a stopping airline, and the stopping short section refers to a route section from the departure place to the stopping place or from the stopping place to the destination, for example, taking an airline AB as an example, from a, to B, and to C, then the stopping long section is a-B, and the stopping short sections are a-C and C-B.

Therefore, for the same measurement data, due to the fact that the target airline and the reference airline have different types of stop, the measurement models may also be different, and therefore, the corresponding measurement models need to be selected according to the types of stop of the target airline and the reference airline, and based on this, taking class-average passenger volume X1 and class-average discount X2 as examples, specific measurement examples are given:

it should be noted that, for the target route and the reference route, which have a common originating airport or arriving airport, the airport different from the reference route in the target route is the measured airport, and the target route can be measured by acquiring data of all routes of the measured airport and combining the data of the reference route. It should be understood that all routes from the reckoning airport should include all direct flight, transit routes from the reckoning airport to take off and land.

It should be appreciated that since there may be multiple types of measured and planned flights at a measured airport, the type of flight selected for measurement may be determined based on the type of stoppage for the target flight path, as shown in table 2, which gives an exemplary priority example for selecting the measured and planned flight.

TABLE 2

Target route	Selecting and calculating flight segment priority
		Direct flight segment	Straight flying section>Short section of warp stop>Warp stop long section
Short section of warp stop	Short section of warp stop>Straight flying section>Warp stop long section
		Warp stop long section	Warp stop long section>Short section of warp stop>Straight flying section

In the field of airline estimation, the influence of the type of parked airlines on estimation is generally considered to be small, the traditional mainstream view considers that the flight conditions of airlines such as range and flight time are only related to environmental factors and self factors of airplanes, such as the linear distance of airlines, weather, airplane models, driving speed and the like, and the data such as average class passenger volume, average class discount and the like are related to the development condition of the city where an airport is located and the specific policy of an airline company, therefore, in the traditional estimation method, the type of parked airlines is not taken as a factor to be considered, but the invention selects a reference airline to predict a target airline, therefore, although according to the traditional estimation scheme, the type of parked airlines is not related to the accuracy of the estimated data, a large amount of tests show that the type of parked airlines is distinguished from the type of parked airlines of the reference airline and the type of parked airlines of the target, compared with the measurement and calculation using the same measurement and calculation model, the accuracy is improved by about 10%, so that the measurement and calculation errors caused by different types of the menstrual stops can be reduced by selecting different measurement and calculation models for measurement and calculation according to the types of the menstrual stops of the airline, and the measurement and calculation accuracy is further improved.

Optionally, in some possible implementations, before the server sends the measurement result to the user side, the method further includes:

the server judges the similarity between the target air route and different airports of the reference air route according to at least one preset judgment condition, when the judgment condition which does not meet the similarity requirement exists, the server calculates the difference value of each judgment condition which does not meet the similarity requirement among the different airports, reads the corresponding deviation value from a preset configuration table according to each difference value, and corrects the measurement and calculation result according to all the obtained deviation values.

It should be understood that the determination condition may be set according to actual requirements, and may be, for example, airport level, throughput, presence or absence of high-speed rail, urban population difference, urban comprehensive development index difference, and the like. A specific example is given below, and for example, when the following determination condition is satisfied, the similarity requirement can be considered to be satisfied:

1. airport class identity

2. Airport throughput difference is within 30%

3. The high-speed rail is within 4 hours

4. Urban population differences:

if the population is less than 1000 ten thousand, the difference is within 30 percent

Or the population number is more than 1000 ten thousand, and the difference is within 1000 ten thousand

Or the reference city and the measured city are respectively over 1000 ten thousand, and the difference is within 30 percent

5. The average class passenger capacity (round trip) is less than 40 people without adjusting deviation value

Class-average passenger volume >0, source big data group

The average class passenger capacity is 0, and the average class passenger capacity can be calculated through a rear-end interface according to the following calculation:

the total number of seats is equal to the number of seats, the average passenger capacity coefficient is equal to 40, and the average passenger capacity is equal to the total number of seats 2

Total number of seats >40 average class factor,

mean shift passenger volume (total number of seats) 2 passenger volume adjustment coefficient + passenger volume deviation value

It should be understood that the deviation value of the passenger volume may be adjusted to increase or decrease, and the adjustment may be negative.

An exemplary average class passenger volume deviation value and discount deviation value calculation method is given below by taking airport throughput and city population difference values as examples:

if the measured airport throughput is smaller than the reference airport throughput, the airport throughput difference value is 1-measured airport throughput/reference airport throughput;

if the measured airport throughput is greater than the reference airport throughput, the airport throughput difference value is 1-reference airport throughput/measured airport throughput;

if the population of the city where the measuring and calculating airport is located is smaller than the population of the city where the reference airport is located, the difference value of the population of the city is 1-the population of the city where the measuring and calculating airport is located/the population of the city where the reference airport is located;

and if the population of the city where the measuring and calculating airport is larger than the population of the city where the reference airport is located, the difference value of the population of the city is 1-the population of the city where the reference airport is located/the population of the city where the measuring and calculating airport is located.

Then, according to the difference value between the population and the throughput, the passenger volume deviation value after the throughput adjustment and the passenger volume deviation value after the city population adjustment are taken out from the deviation value configuration table, and then the passenger volume deviation value is calculated according to a passenger volume deviation value algorithm formula.

TABLE 3

The passenger volume deviation value is the passenger volume deviation value/2 + passenger volume deviation value/2. The calculation of the discount deviation value is similar and will not be described again.

After the passenger volume deviation value and the discount deviation value are obtained, the average passenger volume and the average discount can be corrected, and the correction of the average discount is taken as an example and explained below.

Average shift discount is calculated as average shift discount plus discount deviation value.

Alternatively, if there is a high-speed rail between the airports where the target airlines are located, then the correction may be made in the following way, taking the average class discount as an example: if the corrected average shift discount is not more than 0.2, the market of the high-speed rail motor car does not need to be judged, and if the corrected average shift discount is more than 0.2, the time length deviation value of the high-speed rail can be judged according to the table 4, and then the correction is carried out again:

TABLE 4

And combining the high-speed rail time deviation value to finally obtain the average shift discount as follows:

and (4) calculating the average shift discount, the discount deviation value and the high-speed rail time length deviation value.

The similarity between the target route and the reference route is judged, and then the deviation value is corrected, so that the measured and calculated result is closer to the reality, the measurement and calculation accuracy is effectively improved, the judgment conditions can be set according to the actual requirements due to the fact that the judgment conditions are judged one by one according to different judgment conditions, and therefore the correction of the measured and calculated result has certain tendency, for example, if an airline company is sensitive to the throughput, the difference value of the judgment conditions of the throughput can be set smaller, the measured and calculated result is corrected accurately in the angle of the throughput, the measured and calculated result is more pertinent, different measurement and calculation requirements can be met, and the practicability and the applicability of the invention are improved.
