Description

[0002] Real-time traffic information generating system using beacon information [

The present invention relates to a real-time traffic information generation system using beacon information. More specifically, the present invention relates to a system and method for generating traffic information by analyzing beacon information transmitted from a driver's smartphone, And the filtering reference data M applied to classify the driver and the pedestrian is automatically set to an optimal value according to the traffic environment, thereby realizing the real-time traffic information Generating system.

Recently, intelligent transportation system (ITS, Intelligent Transportation System) has been studied and widely used due to the development of information communication technology, the spread of telematics devices and the establishment of ubiquitous environment.

Such an intelligent traffic system (ITS) is primarily configured to collect various data related to a vehicle and then analyze and process vast amount of collected data to generate traffic information. Therefore, depending on how accurate the data about the vehicle can be collected The performance, reliability, and accuracy of Intelligent Transportation System (ITS) are fluctuating, and various studies are being conducted on techniques and methods for improving the accuracy and efficiency of vehicle data collection.

Conventional methods of collecting vehicle data include a method using a loop detector and a method using a laser and a radar. However, since the method using a loop detector must be installed so that the loop coil is embedded in the road surface, It is complicated and has a disadvantage that the cost increases. Since the detection range is limited due to the laser, the accuracy and reliability are lowered because the number of vehicles to be sensed is smaller than that of the entire traveling vehicle, and the radar- But also has a high error rate.

In particular, Urban Traffic Information System (UTIS), which has been under various researches in recent years, is a system that accumulates (accumulates) the base station (RSE) connected when the OBE (on-board equipment) However, since the UTIS requires the driver to purchase and install an expensive OBE, a separate dedicated program must be installed in the in-vehicle terminal. It is structurally limited that the detection rate is significantly reduced due to the lack of spontaneity because the driver does not give any profit or compensation to the driver even if the driver installs the terminal in the vehicle.

FIG. 1 is a configuration diagram showing a priority signal control system disclosed in a Korean Patent Registration No. 10-2011-0107567 (entitled "Emergency Vehicle Priority Signal Control System Using Utilized Emergency Vehicles") Patented by the present applicant.

The priority signal control system (hereinafter referred to as "prior art") 100 shown in FIG. 1 includes in-vehicle terminals 101-1, ..., 101-N installed in an emergency vehicle, (Car navigation systems) 111-1, ..., 111-N connected to the UTIS network 110 (N-1), ..., ..., 103-N and base stations 103-1, ..., and 103-N that provide the base station 103-1, ..., And a local traffic center 105 for generating traffic.

The conventional technique 100 configured as described above transmits driving information to the base station 103 connected to the in-vehicle terminal 101 via the UTIS network 110 and the base station 103 transmits the driving information to the in- By transmitting the received driving information to the local traffic center 105 through the communication network, the traffic information can be generated and collected by the local traffic center 105.

However, in the conventional technology 100, since the driver must purchase the in-vehicle terminal 101 essentially and a separate navigation program must be installed in order to receive the traffic information from the local traffic center 105, In addition, there is a problem in that the efficiency of collecting is remarkably low due to the spontaneousness and publicity of the driver.

That is, in the conventional technology 100, the number of vehicles to be sensed is excessively low as compared with the total number of vehicles to be driven, so that the accuracy and reliability of the traffic information are deteriorated.

In order to solve such a problem, a technique and a method for collecting traffic information using a Wi-Fi signal of a mobile communication terminal of a driver have been studied.

When the mobile communication terminal of the vehicle driver enters the communication area of the Wi-Fi access device, the second prior art configured as above transmits the connection determination information including the terminal identification information to the Wi-Fi access device, When the connection information is received from the terminal, connection information including the identification information of the corresponding traffic light controller is transmitted to the traffic control center server. The traffic control center server analyzes the terminal identification information and the traffic light controller identification information of the connection information, Extracts only connection information related to the vehicle, and analyzes the extracted connection information to generate traffic information.

That is, according to the second prior art, the traffic control center server analyzes the connection information transmitted from the driver's mobile communication terminal to generate traffic information, thereby improving the collection efficiency and publicity, and can be used without purchasing a separate dedicated terminal. And the operation cost can be reduced, and the access information transmitted from the mobile communication terminal of the pedestrian is removed using the moving speed, so that the information related to the pedestrian can be accurately removed.

However, since the traffic control center server is configured to filter the access information related to the pedestrian among the collected access information by simply using the moving speed, the second prior art is a method in which, when the vehicle is densely packed and the vehicle speed is slow, There is a disadvantage in that reliability and accuracy of traffic information are deteriorated due to frequent errors that are determined based on the access information of the pedestrian.

In addition, the second conventional technique is configured to determine that the access information having the same terminal ID is detected in both two adjacent Wi-Fi access devices as access information of the vehicle, so that the Wi- In an environment close to the installation interval, an error of judging the access information of the pedestrian as the access information of the vehicle frequently occurs, and the reliability and accuracy of the traffic information are further deteriorated.

In general, the traffic environment such as the traffic congestion rate of the road, the vehicle traveling speed, and the density is varied depending on various conditions such as date, time zone, day of the week, weather, etc. However, It is structurally difficult to accurately detect traffic information because it distinguishes between a vehicle and a pedestrian.

FIG. 5 is a block diagram showing the control center server of FIG. 2. FIG.

5, the control center server 7 includes a control unit 70, a database unit 71, a communication interface unit 72, a parsing unit 73, a search and extraction unit 74, A traffic information generating unit 80, a traffic information generating unit 80, a traffic information generating unit 80, a traffic information generating unit 80, (81).

The control unit 70 is an operating system of the control center server 7 and is a control object 71, 72, 73, 74, 75, 76, 77, 78), (79), (80), and (81).

The database unit 71 stores identification information and location information of each of the roadside repeaters 3-1, ..., and 3-N.

In the database unit 71, road continuity information indicating whether adjacent roadside repeaters 3 are continuously installed along the road is preset and stored.

Connection information received from the roadside repeaters 3-1, ..., and 3-N is stored in the database unit 71. [ At this time, the access information includes the identification information of the mobile terminal and the identification information of the roadside repeater.

In addition, the database 71 stores traffic information generated by the traffic information generating unit 80.

The communication interface unit 72 receives connection information from the roadside repeaters 3-1, ..., and 3-N through the communication network 10. [

The parsing unit 73 periodically crawls the communication interface unit 72 to search for connection information transmitted from the roadside repeaters 3-1, ..., and 3-N, And stores the information in the database unit 71.

The searching and extracting unit 74 searches the database unit 71 every predetermined period T and extracts the stored connection information for the period T. [

The connection information extracted by the search and extraction unit 74 is input to the data classification unit 75 under the control of the control unit 70. [

The data classifying unit 75 analyzes the access information stored during the period T input from the searching and extracting unit 74 and classifies the inputted access information according to the terminal identification information.

That is, the data classification unit 75 can classify the access information by the terminal identification information using the terminal identification information included in the access information.

The classification data classified by the data classification unit 75 is input to the trajectory list generation unit 76 under the control of the control unit 70.

FIG. 6 is an exemplary diagram for explaining the trajectory list generating unit of FIG. 5. FIG.

The trajectory list generating unit 76 analyzes the classification data inputted from the data classifying unit 75 and generates trajectory list information for each of the terminal identification information.

In general, when the vehicle is moving very fast, the driver's mobile terminal is connected to at least two roadside repeaters 3 during the period T, so that the data classification unit 75 There are two or more pieces of connection information having the same terminal identification information but different side-by-side repeater identification information.

Accordingly, the trajectory list generator 76 tracks the trajectory of each mobile terminal through the location information and the road continuity information of the predetermined roadside repeaters 3, and then displays the trajectory indicating the continuous traffics And generates list information.

For example, as shown in FIG. 6, the roadside repeater 'A' installed at an intersection is continuous with the roadside repeaters 'B', 'C', 'D', and 'E'. At this time, when the vehicle V moves to the first road 201 -> the intersection 205 -> the fourth road 204 during the period T, the mobile terminal of the vehicle driver moves the roadside repeater 'B', ' B ',' A ', and' E 'are added to the access information of the corresponding mobile terminal classified by the data classifying unit 75, And the trajectory list generator 76 generates the trajectory list for the corresponding mobile terminal as 'B' -> 'A' -> 'E' through the classified data.

The trajectory list information generated by the trajectory list generation unit 76 is input to the pedestrian access information filtering unit 77 under the control of the control unit 70.

Fig. 7 is a block diagram showing the pedestrian access information filtering unit of Fig. 5; Fig.

As shown in FIG. 7, the pedestrian access information filtering unit 77 includes a number-of-terminals calculation module 771, a comparison module 773, and a filtering module 775.

The per-terminal list quantity calculation module 771 analyzes the list list information generated by the trajectory list generator 76 to calculate the list quantity N, which is the number of the roadside repeaters connected to each terminal identification information. For example, when the trajectory list information is 'B' -> 'A' -> 'E', the trajectory list quantity N becomes '3'.

Also, the locus list quantity N calculated by the terminal quantity list quantity calculation module 771 is input to the comparison module 773.

The comparison module 773 compares the input trajectory list quantity N with the filtering reference data M used in the previous cycle.

The filtering module 775 determines that the access information is access information by the driver mobile terminal if the number of trace list N is equal to or larger than the filtering reference data M by the comparison module 773. [

The filtering module 775 determines that the access information is access information by the pedestrian mobile terminal if the number N of the trace list is less than the filtering reference data M by the comparison module 773. [

At this time, the filtering reference data M is defined as a reference value of the number of trajectory list items for classifying the access information into vehicles or pedestrians. If the filtering reference data M increases, only the data detected by the plurality of roadside repeaters The accuracy is increased but the sample quantity is reduced. On the other hand, when the filtering reference data M is decreased, the connection information detected by a small number of the roadside repeaters is recognized as valid data, But the accuracy is lowered.

For example, when the filtering reference data M is '1', since the access information is transmitted to at least one of the roadside repeaters 3 during the period T no matter how slowly the pedestrian moves, The number N of the locus list of the connection information of the identification information is detected so that the pedestrian access information filtering unit 77 judges that not only the vehicle but also the access information by the pedestrian are all valid information, will be.

On the other hand, if the filtering reference data M is set to an excessively high " 20 ", it is impossible for the vehicle to move 20 twenty-way transponders during the period T so that the pedestrian- Access information is also misjudged as a pedestrian and filtered, which reduces accuracy.

In addition, the filtering reference data M is influenced by the size of the installation interval of the roadside repeaters 3. For example, it is preferable that the filtering reference data M in the region where the installation interval of the roadside repeaters 3 is narrow is formed larger than the filtering reference data M in the region where the installation interval of the roadside repeaters 3 is large. This is because when the installation interval of the roadside repeaters 3 is narrow, the number of the roadside repeaters 3 that can be connected to the pedestrian mobile terminal during the period T increases, so that the higher the number of the filtering reference data M is, .

That is, since the filtering reference data M is directly related to the reliability and accuracy of traffic information generation, in the present invention, the filtering reference data M is set to an optimum value corresponding to the traffic environment, The setting method will be described later in detail with reference to FIG.

8 is a block diagram showing the checking and judging unit in Fig.

The checking and judging unit 78 includes a statistical data management module 781, a subtraction module 783, and a comparison and judgment module 785 as shown in FIG.

The statistical data management module 781 processes the traffic information stored in the database unit 71 to generate and update statistical data for each category such as date, time zone, and day of the week.

The subtraction module 783 searches the statistical data to extract the number of pieces of connection information (hereinafter referred to as sample amount) S 'corresponding to the same time zone, day of week, and date as the present time.

The subtraction module 783 also subtracts the sample quantity S 'from the quantity S of the access information filtered by the pedestrian access information filtering section 77 to calculate the subtraction value S-S'.

The comparison and determination module 785 compares the absolute value of the subtraction value with the threshold value when the subtraction value S-S 'calculated by the subtraction module 783 is' -', and if the absolute value of the subtraction value is It is determined that the filtering reference data M is not changed. If the absolute value of the subtraction value is greater than or equal to the threshold value, it is determined that '1' is added to the filtering reference data M.

Also, the comparison and determination module 785 compares the subtraction value with the threshold value when the subtraction value S-S 'calculated by the subtraction module 783 is' +', and if the subtraction value is less than the threshold value, It is determined that the reference data M is not changed. If the absolute value of the subtracted value is greater than or equal to the threshold value, it is determined that the filtering reference data M is subtracted by '1'.

The filtering reference data setting unit 79 sets the filtering reference data M in accordance with the result determined by the comparing and judging module 785. [

That is, if the absolute value of the difference value is equal to or greater than the threshold value by the comparison and determination module 785 and the difference value S-S 'is' -', the filtering reference data setting unit 79 sets the filtering reference data M + 'And the subtraction? Is equal to or larger than the threshold value by the comparison and judgment module 785, the filtering and judgment module 785 updates the filtering reference data M by adding' 1 ' The filtering reference data M is updated by subtracting '1' from the reference data M.

The filtering reference data M set by the filtering reference data setting unit 79 is used in the pedestrian access information filtering unit 77 of the next cycle.

The traffic information generating unit 80 analyzes and processes the traffic information filtered by the pedestrian access information filtering unit 77 to generate traffic information. At this time, the traffic information may be composed of the quantity (N ') of the traveling vehicle, the congestion rate, the density, and the average speed.
