Description

System of buses, stations and centers with information exchange

technical field

The invention relates to the technical field of information exchange of a public transport system, in particular to a bus, station and center system with information exchange, which can provide the center and users with bus and station information.

Background technique

In recent years, there have been a lot of information collection and release technologies about public transport systems, especially buses and stations. In the current bus service, through the global positioning system, mobile communication system, image processing and other technologies, the center and passengers can know the bus location, route, estimated time of arrival, road traffic conditions and other information.

For example, a Chinese patent (01235755.3), electronic bus stop sign, introduces a kind of electronic stop sign installed at the station. Through the Global Positioning System (GPS) and the Global System for Mobile Communications (GSM), the operating position of the bus can be provided to the traffic center and users. A Japanese patent (11-31295) detects road surface information by installing a camera on a car. Another Japanese patent (2003-16587) calculates the estimated time of arrival of a bus through a global positioning system. They publish the bus information of some lines on the Internet, including the timetable, the current location of the bus, and the type of bus (with or without steps to facilitate passengers in wheelchairs). Simultaneously, another Japanese patent (P2003-6784A) has introduced a kind of bus concept that dynamically adjusts schedule operation according to passenger's ride demand.

However, more bus information cannot be provided in time, such as whether the bus is air-conditioned, the congestion on the bus, the ticket price, and whether the monthly pass can be used, etc. Many waiting passengers do not know the situation of several buses that will enter the station, so they can only choose the bus that arrives first.

On the other hand, the information of the station cannot yet be provided, such as the congestion of waiting passengers at the station. The center does not know the information of the station, and cannot dynamically adjust the operation of the fleet to adapt to the passenger flow at that time.

The traditional bus system that dynamically adjusts operation according to passenger demand mainly considers adjusting the fleet operation according to the random needs of users, but does not consider selecting buses according to the type of bus and the current operating conditions. On the other hand, when a passenger transfers from a bus to another means of transportation, he has to estimate the estimated arrival time of each optional bus to the transfer point, and find out the timetable and operating conditions of other means of transport to judge the choice. It is obviously very inconvenient to find out the method that is most suitable for them.

Contents of the invention

The purpose of the present invention is to provide a system of bus, station and center with information exchange, wherein the bus can collect and send the information of the bus to the center, including congestion status, bus type, charging information, etc., and then receive from the center, including Information on bus fleets and stations along the route.

Another object of the present invention is to provide a kind of station, and it can not only display information such as the crowded situation on the incoming bus, bus type, bulletin on the electronic stop sign, can also collect information at the station. In addition, the station can also send information to the user terminal.

Another object of the present invention is to provide a bus fleet operation management function that can meet the specific requirements of elderly and disabled passengers, such as whether the type of bus has steps, or whether the bus can carry passengers in wheelchairs. This management function can also provide sufficient information to transfer passengers to help them easily transfer from the bus to other means of transportation at the transfer station.

According to a kind of bus and station system with information exchange function of the present invention, it comprises data acquisition, communication, signal processing, and display device, carries out the information exchange of bus and station with the user, such as the crowded situation on the bus, the bus type, Information on fares and congestion at stations. It is characterized in that: the bus and the station send the data to the center, and after the center processes the data, it is converted into a certain data format and sent to the electronic stop sign of the corresponding station, the bus display, or the personal terminal. The data collected by buses and stations includes images captured by cameras, congestion conditions, bus types, fare information, whether there are disabled passengers on board, etc. The format of the data is different for different terminals.

Technical scheme of the present invention is as follows:

A system of buses, stations and centers with information exchange, comprising buses, stations and centers,

The bus detects the information in the car and communicates with the outside world through wireless means, and is used to exchange information with the center and through the center and the station;

The station detects the information of the station, sends information to the outside, receives the information of the approaching bus, and displays the information, which is used to exchange information with the center and through the center and the bus;

The center receives the information from the bus and the station, stores the information, converts the information according to the type of the information, and sends the information to the bus and the station.

The bus information includes passenger congestion in the bus.

The station information includes the congestion status of waiting passengers at the station.

According to the above system of bus, station and center with information exchange, said bus includes a detector, an information processor, a display, and a transceiver. The detector is used to detect the passenger congestion in the car, the information processor is used to process the data collected by the detector and the data sent from the center, the display is used to display the information sent from the center, and the transceiver is used to transmit signals to and from the center Upon receiving the signal, each bus is assigned a number for identification.

The camera captures images of the interior of the vehicle and can monitor the situation inside the vehicle and detect congestion. In order to overcome the overlap problem, several cameras can be installed at different positions in the car to take pictures from different angles. Crowd information can also be collected by installing sensors on the seats. The information processor processes the information collected by the detector. Congestion information can be calculated from it. The monitor displays the information sent from the center, including the distance between the bus and several buses in front, the congestion situation of the bus ahead, the congestion situation of the arrival station ahead, etc. Transceivers send signals to and receive signals from the hub. Each bus is assigned a number for easy identification by the center. In networks that support packet switching, this number may be an Internet Protocol (IP) address.

According to the above bus, station and center system with information exchange, the station includes an electronic stop sign, a detector, an information processor, and a transceiver. The electronic stop sign is used to display the information of the approaching bus, the detector is used to detect the congestion of passengers waiting at the station, the information processor is used to process the data collected by the detector and the data sent from the center, and the transceiver is used to transmit signals to and from the center Receiving the signal, each station is assigned a number for identification.

The electronic stop sign displays the information of the bus that is about to enter the station, including the congestion status on the bus, bus type, fare information, operating location, estimated arrival time, transfer information, etc. The camera captures images of the station. The congestion of waiting passengers at the station can be detected by cameras. The information processor processes the data sent from the probes, such as images from the cameras, and the data received from the center. Transceivers send signals to and receive signals from the hub. Each station is assigned a number for identification by the centre. In networks that support packet switching, this number may be an Internet Protocol (IP) address.

According to the above system of bus, station and center with information exchange, the center includes a management server, a display, and a transceiver. The management server receives, stores, converts and sends bus and station data, including congestion status, bus type, fare information, whether there are disabled passengers on board, etc. The display monitors the situation of the bus and the station through the image sent back by the camera. Transceivers receive signals from buses and stations and send signals to buses, stations and other users.

According to the above system of bus, station and center with information exchange, there is included a second type of transceiver for wireless communication with personal terminals of passengers near the station, different from the first type of transceiver for wireless communication with the center. It can communicate with the terminal in a limited range near the station. It can send the information sent from the center to the station to the terminal, send the terminal's display request information to the center, and send the center's answer to the request information to the terminal.

Stations can receive bus type information, bus interior images, and other station images through the center, and send them to personal terminals. The personal terminal can receive bus information through the station; if the bus is also equipped with a transceiver that can communicate with the second transceiver at the station, when the bus enters the communication area, the personal terminal can also receive information directly from the bus. Stations and centers have combined information of stations, bus routes, and bus travel directions, so users of personal terminals can reduce input operations, and can communicate with stations to obtain information just by inputting departure and destination.

According to the above-mentioned system of bus, station and center with information exchange, the data of the center has various bus information arranged according to bus numbers. This information includes: static information, such as whether there is air conditioning, whether there are steps, and whether passengers in wheelchairs can be transported. Buses that can carry passengers in wheelchairs have the function of judging whether such passengers are on board. When wheelchair passengers get on and off the bus, the driver sends this status information to the center through the transceiver. Passengers who need to use the bus service operated according to the passenger's riding needs get the information collected by the center through the Internet, and send the boarding location, boarding time, alighting location, bus information, and bus transfer information to the center. After the center receives the passenger's ride demand, it calculates a new driving route according to the demand, and takes this ride demand information into account, and recalculates the estimated time to arrive at each station along the route. These results are sent to the requesting passenger. In addition, the center sends new routes, parking locations, and passenger needs to the bus, which broadcasts this information to the driver through a display or speaker. After confirming the information, the driver sends an acknowledgment signal for receiving instructions. Estimated arrival times are revised at each station and demand information is displayed on buses that receive passenger demand.

According to the above system of bus, station and center with information exchange, said center is connected with management servers of other transportation centers, such as railways, subways, to receive route, schedule and service information in time. The center estimates the arrival time of each bus at the transfer station, and extracts the information of other transportation methods at the transfer station according to the timetable close to the estimated arrival time and the service conditions of other transportation methods. The extracted information is sent to the station and displayed on the electronic stop board together with the information of the relevant bus, or sent to the passenger's personal terminal through the second wireless communication function. Moreover, this information can be sent to the bus from the center or through the station, so that the passengers on the bus can also know the information. If real-time road traffic information can be used, the center can be connected with the management center providing road traffic information to obtain the travel time of road traffic for estimating the arrival time of the bus.

The advantages of the present invention are: it can collect and publish more and more accurate bus and station information, not only can help the center to manage the fleet more efficiently, reduce operating costs, but also provide passengers with more useful information, such as Bus congestion, bus types, and fare information make it easier for passengers to choose the bus service that suits them.

Detailed ways

Figure 1 shows the information exchange between buses, stations and centers. The public vehicles include: buses, trams, trolleybuses, light rail trains and subway trains. Every bus and every station is assigned a number, which can be an IP address. The transmission medium adopts a wireless communication network, such as a cellular network, a wireless local area network, or a dedicated short-range communication (DSRC). Bus information, including degree of congestion, bus type, charging information, whether there are passengers in wheelchairs on board, etc., is collected by vehicle-mounted detectors, such as cameras, and the cameras described in the present invention can adopt general cameras, such as analog cameras, Or adopt a digital camera, and send it to the center through a transceiver after being processed by an information processor, and its process is as in (101); After the data is processed in the center, it is sent to the electronic stop sign of the station, and its process is as in (102). The centers mentioned in the present invention include: bus company operation management center, traffic information service center, traffic dispatching center, traffic command center and information exchange center.

On the other hand, station information, such as the degree of congestion, is collected by detectors installed in the station, such as cameras, and then processed by the information processor and sent to the center through the transceiver. The process is as in (103); after the center processes the data, Send to the on-board display, its process is as (104).

Figure 2 shows a schematic diagram of a bus. Installed on it are: a detector, such as a camera (201), an information processor (202), a display (203), and a transceiver (204).

Detectors are used to detect bus information, including congestion status, service status, etc.

Possible methods for detecting bus congestion are:

One method is: in order to overcome the overlapping problem, to cover the panoramic view of the bus, install several cameras (201) in different places on the bus. For example, the company is installed at the four corners of the car or installed at the top of the car with a wide-angle lens. They work on a set schedule, such as taking images every minute, and the shooting interval can be adjusted according to communication costs and operator requirements. In addition to this method, the camera (201) can also work according to the shooting requirements. If the vehicle-mounted device receives a shooting request from the center, the information processor (202) will turn on the camera for shooting. After the in-vehicle image is taken, it is compressed by the information processor (202), and sent to the center through the transceiver (204).

Another method is to install sensors on each seat, and select several locations on the aisle to install sensors. The sensors can be triggered by light, such as infrared rays, or by pressure. After the passenger triggers the sensor, the signal is transmitted to the signal processor (202), and the congestion situation in the car is calculated and sent to the center through the transceiver (204).

In order to identify different types of buses, such as whether the buses are equipped with air conditioners, ticket prices, and whether monthly tickets can be used, each bus is assigned a number, which can be an IP address in a packet switching network, such as a GPRS network. In this way, each data sent to the center is assigned this number, and the center can identify the bus that sends the data through it, and send the data to the corresponding station.

The display (203) is used to display various information sent from the center to drivers and passengers.

The information processor (202) and transceiver (204) are responsible for information processing and transmission. The information processor (202) includes analog-to-digital conversion (A/D), encoding and decoding, encryption and decryption, and image compression. Images can be compressed into JPAG format. For different communication media, such as cellular network, wireless local area network, or short-range dedicated communication (DSRC), the transceiver (204) can be multi-mode or single-mode. In the multi-mode mode, the transceiver antenna can work in a variety of networks and has multiple air interfaces; in the single-mode mode, the choice of network depends on the construction cost, communication cost, and coverage. In order to detect the location of the bus, a GPS antenna may be included in the transceiver (204).

Figure 3 shows an embodiment of a display mounted on a bus. The device can be used for bus operation management. It can be installed on the dashboard in front of the bus driver, or it can be installed in other places in the car where passengers can easily browse. Messages (301) from the center are displayed on the screen in text form, for example using Short Message Service (SMS) in cellular networks. The screen is a liquid crystal display LCD (302). When the message arrives, the loudspeaker (303) sends a prompting sound. In this way, the driver or passenger is reminded that a new message has arrived. The information includes: the distance to the bus in front, for example, 350 meters from the bus to the first bus in front, 750 meters to the second bus, and 1200 meters to the third bus, the congestion of the bus ahead, such as the nearest bus in front One bus is very crowded, the second and third buses ahead are not crowded, the congestion situation at the next stop, and other useful information. Through this information, the driver can adjust the distance to the vehicle in front, improve operational efficiency, and ensure that waiting passengers do not have to wait too long.

Other types of displays containing the information described above may also be implemented.

Other information, such as news, announcements, advertisements, can also be displayed to passengers.

Figure 4 shows a schematic diagram of a station. The stations include: stations for buses, trams, trolleybuses, light rail trains and subway trains.

The station is equipped with a transceiver (401), an information processor (402), an electronic stop sign (403), and a camera (404).

The transceiver (401) receives the information sent from the center, and after being processed by the information processor (402), it is displayed on the electronic stop sign (403). The information includes: the congestion status of several buses that are about to enter the station, the bus type, the charging situation, and other information.

The image of the station is captured by the camera (404), and is sent to the center through the transceiver (401) after being compressed by the information processor (402). It works on a programmed schedule, such as taking images every minute, or according to the requirements of the center operator.

Figure 5 shows an embodiment of an electronic stop sign installed at a station. In addition to the information displayed on the traditional stop sign, line number (501), station name (502), first and last train time (503), and stations along the line (504), it also has several different features: the bus that is about to enter the station Information (506) such as position and congestion situation (505), bus type, charge.

The location information (505) of the bus is realized by the Global Positioning System (GPS), and it is represented by the position of the light on the station along the line on the stop sign: when a bus leaves station A and sails to station B, the light under station B Light up, when you arrive at station B, the small light goes out, the small light at the next station C turns on, and so on. Passengers can know where the bus is running by the position of the light on.

The congestion information (505) of the bus is realized by the on-board detector, and is indicated by the number of small lights on the stop sign along the station: 3 lighted lights indicate high congestion, and 2 lighted lights indicate mild congestion , 1 lit small light means that it is not crowded, that is, there are vacancies.

It is also possible to reflect the degree of congestion in the car by the number of passengers observed by the camera installed in the car or the distance between passengers, and the image information is fed back to the center. After the center makes image processing or image statistics, the center The congestion status is displayed on the electronic stop sign sent to the station.

The type of bus that is about to enter the station, such as whether there is air conditioning, whether there are disabled passengers, and the fare information (506), are displayed in Chinese and English on the top of the stop sign. A light emitting diode screen (LED) may be used. Other information such as weather conditions, announcements can also be displayed on it.

The type of bus can be realized by numbering the bus, and different numbers represent different bus types. For example, air-conditioned cars, buses, and trams can be represented by different numbers. It can be displayed on the electronic stop sign.

Other electronic stop signs containing the above information can also be implemented.

Figure 6 shows a schematic of the center. It includes: a management server (601), a display (602), and a transceiver (603).

The management server (601) stores the data returned from the bus and the station in the database, and converts the data into a certain format according to different publishing terminals, such as station electronic stop signs, bus displays, and personal terminals. The stored data includes: time, bus number, route number, bus type, location, congestion, whether there are disabled passengers in wheelchairs, etc. It can provide operators with fleet management evidence and records. The format of the published data is different according to the terminal: for the electronic stop sign of the station, the data is sent in a special coded way to control the small lights; for the display on the bus, the data is sent in text short message (SMS) format; for the personal terminal, Such as mobile phone, the data is sent in multimedia short message (MMS) format, the user only needs to enter the destination name and send it to the application service provider (ASP), and then he can get the recommended bus information, including the type of bus, congestion status, fare and other information. The user can also see the image processing of the bus congestion made by the center or the statistical image of the bus. The congestion status is shown by symbols of different colors, red for high congestion, yellow for light congestion, green for no congestion, or by different numbers of symbols, three symbols for high congestion, two symbols for light congestion, one symbol Means not crowded. The above application can be implemented by installing client software on the user terminal, and the programming language can be Java.

The display (602) is connected with the transceiver (603) for monitoring the situation in the vehicle through the received images. The operator calls up the latest image by entering a different bus number on the computer. The image interval can be adjusted as needed. The above applications can be realized by installing server-side software on the central server.

The transceiver (603) receives and sends information over the network. Used to receive signals from buses and stations and transmit signals to buses, stations or other users.

Fig. 7 shows the flow chart of judging the congestion situation by the information processor on the bus according to the collected images.

A method for judging the congestion situation in a bus in a bus, station and center system with information exchange, the specific process is as follows:

1. When each bus is empty, the cameras installed in different positions take images from different angles, and the images are stored in the processor as a criterion for judging the congestion situation; points on several images are selected as judgment points , such as selecting one point on the backrest of each seat, and several points on the aisle;

2. After the camera takes images from different angles, the information processor compares them with the reference images stored in the processor. If the judgment point is covered, the information processor judges that the space at this point is occupied by passengers;

3. If less than 100% of the judgment points on the seats are covered, the congestion situation is rated as "not crowded", that is, at least one seat is vacant; if 100% of the judgment points on the seats are covered, If less than 100% of the judgment points on the aisle are covered, the congestion situation is rated as "slightly crowded"; if 100% of the judgment points on the seats and aisles are covered, the congestion situation is rated as "highly crowded".

Fig. 8 shows the flow chart of judging the congestion situation by the information processor on the station according to the collected images.

A method for judging the congestion situation at a station in a bus, station and center system with information exchange, the specific process is as follows:

1. When no one is waiting at each station, the image is captured by the camera and stored in the processor as a criterion for judging the congestion situation. Several points on the image are selected as judgment points, such as several points on the roadside point;

2. After the camera captures images, the information processor compares them with the reference images stored in the processor. If the judgment point is covered, the information processor judges that the space at that point is occupied by waiting passengers;

3. If less than 50% of the judgment points are covered, the congestion situation is rated as "not crowded"; if less than 100% and greater than 50% of the judgment points are covered, the congestion situation is rated as "slightly crowded"; if 100% % of the judgment points were covered, and the congestion situation was rated as "highly congested".

Fig. 9 shows a schematic diagram of the second communication device: wireless local area network installed on the station described in Fig. 4 .

The station (904) includes an information processor (905), an electronic station sign (906), a transmitter (903) for communicating with the center, and a wireless local area network base station (902) for communicating with nearby terminals. When the waiting passenger holds PDA (personal digital assistant) (901) and enters the communication range of the wireless local area network base station (902) of station (904), the wireless communication of station and PDA can be established.

Fig. 10 shows an embodiment of the second type of communication using a wireless local area network for wireless communication at a station.

A communication method with a system of buses, stations and centers for information exchange, including buses, stations and centers, the steps are as follows:

It describes the information exchange process between PDA as personal terminal, station and center. First, the center sends data to display on the electronic stop sign (906) of the station (904), and its process is as (1001); after the PDA (901) enters the communication range of the station (904), it sends a communication link connection request, and its process is as follows (1002); after the station (904) sends confirmation information to respond to the connection request, its process is as (1003), and the data on the electronic station board is sent to the PDA (901), and its process is as (1004); the PDA is in accordance with the corresponding format Information is displayed on its screen. Then the user sends a request for obtaining other information of the center to the station (904) through the PDA (901), the process is as in (1005), the station (904) sends it to the center after receiving the request, the process is as in (1006), and the center makes the request according to the request. After corresponding information is sent to the station (904), its process is as (1007), and the station (904) forwards the information to the PDA (901) (1008).

Figure 11 shows an example of an image on a PDA screen. The left side (1101) of Fig. 11 has shown the embodiment on the PDA display screen of the data sent to the station from the center, shows the situation of the position of the station and bus. When a bus on the screen is selected by the electronic pen of the PDA, the image captured by the camera in the bus and sent to the center and other information sent from the center and obtained through the station are displayed on the display screen of the PDA, showing the bus number, The bus type, the crowded image of the distance between passengers in the car, and the number of passengers in the car, as shown in the right side (1102) of Figure 11.

Fig. 12 shows a schematic diagram of the information processing process of the central management server. The management server (1201) includes three processes as described below. Process 1 (1202) receives data from bus, includes the processing of bus numbering, bus type, position, the crowded image of passengers in the car mentioned above and the data of its passenger number statistics, updates the bus and the database of the station that management server connects; Process 2 (1203) discloses the relevant information of buses and stations on the Internet; process 3 (1204) is responsible for processing passenger demand information, receiving passengers' demand for bus rides, recalculating the driving route according to the demand, and predicting the time to arrive at each station , Send confirmation information to passengers who reserved seats, send new routes, and estimated arrival times to various stations and buses. At this point, new functions can be added to the process to calculate the cost of changing the route according to the demand, change the fare of the ride appropriately, notify the passenger, and reconfirm the demand. The cost of the change can be calculated from a table based on the rate of change set for the route distance change. These three processes work independently.

Figure 13 shows an embodiment of the subsystem implementing bus information management, publicizing bus information, and adjusting bus operation and estimated arrival time at each station according to passengers' riding needs. The management server (1302) of the center (1301) is connected with the bus database (1303), which includes the bus data table (1304). The bus data table (1304) includes bus number, route number, bus type, congestion status, and information on whether there are disabled passengers. The management server (1302) updates the information of the bus database (1303) according to the information obtained from the bus (1306) at any time. The updated information can be confirmed on public websites on the Internet through personal terminals (1305), such as home computers and mobile phones. The bus operation process according to passenger's ride demand has been described in Figure 12. The bus (1306) displays the information received from the center (1301) on the on-board display (1308) through the information processor (1307). The driver of the bus (1306) confirms the new travel route and needs, such as the boarding information of passengers in wheelchairs, and sends confirmation information to the center (1301). The management server (1302) updates its database for the bus whose operation is adjusted according to passenger demand, and sends relevant information to the station. An example is: when a passenger in a wheelchair who sends a ride demand gets on the bus, the driver turns on the switch (1309) to show that there is a passenger in a wheelchair to take the bus, and when the passenger gets off the bus, the driver turns off the switch (1309). This information is simultaneously sent to the center (1301) and stored in the bus database (1303).

Fig. 14 shows an embodiment in which the bus and station center (1401) is connected with the railway information center (1403) and the road traffic information center (1404). In the center (1401), the management server (1402) predicts the time of arrival at the station according to the information obtained from the outside, that is, the estimated arrival time of the transfer station is calculated through the traffic time of the road traffic information center (1404). This process is timed at each bus and interchange merge. Then, select the railway information close to the time of arrival at the transfer station from the railway timetable, and further extract its related real-time service information. Simultaneously, the selected railway information is sent to each display of the bus (1405) and the station (1406) passing through the transfer station. As shown in FIG. 9, the information can be sent to the personal terminal PDA (1407) through the wireless local area network of the station (1406). This information may also be further widely published on the Internet.

The above-described system of buses, stations and centers with information exchange can be applied to taxi services. Passengers can choose a taxi through the taxi information provided. The above-mentioned method of adjusting the mode of bus operation and recalculating the route according to the needs of passengers can also be applied to taxis as a general function.

The charging system of the above-mentioned bus, station and center system with information exchange is as follows: the center calculates the cost and fee for carrying each passenger according to the number of passengers, route distance, and vehicle class and applies it to the bus or taxi service in real time. Then the center displays the calculated cost to the passenger before the passenger reserves the seat and gets on the bus, the passenger can reserve the seat according to the displayed cost, and the ride agreement is reached when the reservation is paid. Riders can pay before or after their ride, and the cost varies depending on the payment method. Through this, passengers can choose the most suitable bus or taxi not only according to the route and vehicle class, but also according to the cost.

The above-mentioned system of buses, stations and centers with information exchange can also be applied to the operation and management of bus companies. When there are many passengers boarding a bus at a station, and there are passengers waiting for the bus, their images are transmitted to the center. The center forwards the congestion information of the bus to the next bus, and its driver adjusts the distance from the bus in front to shorten the waiting time for passengers. In this way, the bus company can adjust the operation of the fleet according to the passenger's demand in a timely manner, improve efficiency and reduce costs.

If the camera is installed on the long-distance passenger bus, it can enhance the security of the operation. The working mode of the camera, which can start shooting at any time according to the requirements of the center, can be used in emergency situations. When there is a problem with the bus, the center can check the images in the bus in time. At the same time, the periodic shooting mode of the camera can be used to monitor the driver's working conditions and ensure driving safety. If an illegal incident occurs on the bus, the images captured by the camera can be used as evidence to track and prosecute the offender.

If a second wireless communication device, such as a wireless local area network, is installed at the bus stop, the broadband application of the Internet will be greatly promoted. Waiting passengers can use it to download real-time traffic information, multimedia entertainment information and other interesting content.

Through the above description, it can be seen that a bus, station and center system with information exchange according to the present invention can not only be used for collecting and distributing relevant information of buses and stations, but also exchange more useful information. It can also be used in railway transportation system and civil aviation transportation system.
