[0002]

2. Description of the Related Art One of fixed path moving object management systems includes:
There is a bus approach information guidance system that guides and displays bus approach information to bus users. The system includes a bulletin board provided at each bus stop, a bus passing information transmitting device mounted on each bus, and transmitting a bus passing information when the bus passes through the bus stop, and a bus passing information transmitting device provided at the center. Based on the bus passage information transmitted from the bus passage information transmission device, a bus position information management device that manages the position of each bus in operation (operation status) and guides and displays bus approach information on a bulletin board at each bus stop. It is configured.

In this bus approach information guidance system, when a bus passes a certain bus stop, a bus passing information transmitting device mounted on the bus transmits information (bus passing information) indicating that the bus has passed the bus stop. At the center, when the bus position information management device receives the bus passage information, the information indicating that the bus has left the previous bus stop is displayed on the bulletin board of the next bus stop. Such a guidance display is performed on a bulletin board at each bus stop. The travel time to the next bus stop or the like can be calculated from information such as the position information of the bus stop that has passed and the transmission time of the bus passage information, and the time until the bus arrives (bus approach information) can be displayed.

It comprises a position measurement device 21 having a measurement function and a position measurement processing unit 22.

The position measuring device 21 is installed at a center (fixed station) and sends out its position data (GPS data). The position measurement processing unit 22 compares and compares the position data of the fixed station obtained from the position measuring device 21 with the position of the fixed station which is given in advance (accurate position, which is set as a reference point in this case). Thus, an error (propagation system, satellite system, etc.) included in the GPS signal is detected, and based on the detected error, the position data received from the position transmitting device 10 mounted on the running bus is corrected. Position information (unified data) such as latitude and longitude is generated based on the corrected position data. The position information includes a system number indicating a destination of the bus and information for identifying the bus in order to specify the bus. The generation of the position information is performed in real time on a bus basis. Further, the position information collection station 20 has a function of transmitting the generated position information to the operation information transmission station 40.

This is information for performing comparison management with the actual operation status.
The actual bus operation information is position information related to the operating bus, and the traffic situation of each bus route can be grasped from the position information and the timetable. In addition, when a dispatch change or the like occurs, the operator apparatus 30 can notify the user terminal 50 via the Internet 200 of the change.

The operation information transmitting station 40 is provided at the center and is constituted by an information processing device such as a workstation server, for example, and manages bus operation status and transmits necessary information in response to an inquiry from a user. send. The main configuration of the operation information transmitting station 40 includes an operation information analysis device 41, an operation route time data registration unit 42, and an operation information transmission unit 43. In addition, the operation information transmitting station 40
Bus-based location information (bus number, bus system number, latitude / longitude, transmission time, etc.) transmitted from the location information collection station 20
It also has a function of receiving the information and registering it in the operation management database.

The operation route time data registration unit 42 registers the bus operation route (bus system diagram) and time information (time table data of all bus stops), which are notified in advance by the operator device 30, in the operation route time database. The operation management database combines the position information (bus number, bus system number, latitude / longitude, transmission time, etc.) of each bus transmitted from the position information collection station 20 with the bus system diagram registered in the operation route time database. Or to register.

The operation information analysis device 41 analyzes the bus system diagram and the position information of each bus registered in the operation management database to obtain the current position of the operating bus or predict traffic congestion. In addition, the operation information analysis device 41 responds to an information provision request from the use terminal 50 to obtain bus approach information (bus arrival time) related to the requested bus stop.

The operation information transmitting unit 43 transmits the current position of the operating bus obtained by the operation information analysis device 41 to the operator device 30 as actual bus operation information. Also,
The operation information transmission unit 43 transmits the bus approach information (bus arrival time) calculated by the operation information analysis device 41 and the time required to reach the destination to the user terminal 50. In addition, the operation information transmitting station 40 provides a bus system diagram and bus operation guide information for guiding all bus stops on the Internet 200.

The user terminal 50 is connected to the Internet 200
An operation information transmitting station 40 is an information processing apparatus capable of browsing various information provided on the Internet 200.
It has a function to access the bus operation guidance information page provided above and display the bus operation guidance information on the screen. Examples of the user terminal 50 include a personal computer, a notebook computer, a mobile PDA terminal, and a mobile phone with a browser display function.

The bus operation information guidance in this bus location system includes a step of registering operation schedule information such as a bus operation route and a timetable of each bus stop in an operation route / time database, and a current position (latitude) of the operating bus. Longitude) and the location (latitude and longitude)
The step of registering in the operation management database along with the operation route / time registered in the operation route / time database, and the step of analyzing the data registered in the operation management database and providing the operation information to the user terminal can be roughly divided. It consists of four steps. Hereinafter, each step will be described in detail.

FIG. 2 shows a flow of processing for registering the operation schedule information in the operation route / time database. The registration of the operation schedule information is performed by the operator 30 and the operation information transmitting station 40.
Is done between

First, the operation schedule information transmitting unit 31 of the operator device 30 installed in the bus operator, as the operation schedule information, the operation route information (system diagram) of all the bus routes currently under operation management. The timetable of all bus stops is transmitted to the operation information transmitting station 40 via the Internet 200 (step S10). In the operation information transmitting station 40, the operator device 30
(Step S11), the operation route time data registration unit 42 registers the received operation schedule information (operation route information, timetable) in the operation route / time database (step S12).

In the case where the bus operator does not manage the bus route operation route information and the timetable of all bus stops on the operator device 30, but manages the information on a paper basis, By not directly using the transmission method via the Internet 200 and directly registering the operation route information of the bus route and the timetable of all bus stops by manual input from a keyboard provided in the operation information transmitting station 40, An operation route time database similar to the above can be created.

FIG. 3 shows a flow of a process for obtaining the current position (latitude and longitude) of an operating bus. This latitude / longitude calculation process is performed between the position transmitting device 10 installed on each bus and the position information collecting station 20 of the center.

First, the position measuring device 11 of the position transmitting device 10 mounted on an operating bus receives a signal radio wave from a GPS satellite. Specifically, a signal radio wave from a GPS satellite is received by a GPS sensor via a GPS antenna installed on a roof of a bus or the like (step S20).

The GPS signal received by the position measuring device 11 is automatically transmitted periodically to the position information collecting station 20 via the wireless network 100 by the wireless transmitting device 12 (step S21). At this time, in the position information collection station 20, the position measurement device 21 has received the GPS signal for DGPS calculation (step S22), and the position measurement processing unit 22
By comparing and comparing the GPS signal obtained from the position measuring device 21 with an accurate position of a fixed station (the position where the position measuring device 21 is installed) given in advance, the GP is obtained.
An error included in the S signal is detected, the GPS signal received from the position transmitting device 10 is corrected based on the detected error, and the latitude and longitude are calculated based on the corrected GPS signal (step S23). The calculated latitude / longitude is transmitted to the operation information transmitting station 40.

FIG. 4 shows the position of the running bus (latitude and longitude).
The operation route registered in the operation route / time database
5 shows a flow of a process of registering in the operation management database with time. This registration process is performed between the location information collection station 20 and the operation information transmission station 40.

First, the position information collection station 20 calculates the position information (bus number, bus number) of the bus calculated in steps S22 and S23.
The bus system number, latitude / longitude, GPS transmission time, etc.) are transmitted to the operation information transmission station 40 (step S31). When the operation information transmitting station 40 receives the bus position information from the position information collection station 20 (step S32), the operation route time data registration unit 42 checks the operation route information registered in the operation route / time database in step S12. The received bus position information is registered in the operation management database together with the (system diagram) (step S33). Specifically, on the route of the corresponding bus system number among the operation routes registered in the operation route / time database, the position of the received bus is received at the position of the latitude and longitude closest to the position information (latitude and longitude) of the received bus. The GPS transmission time of the location information of the bus is registered.

As will be described in detail later, when bus stop passage information is used as the bus position information instead of latitude and longitude, the bus stop position information is also registered in the operation route time database, and the bus stop passage time is used. To be registered.

FIG. 5 shows a flow of processing for analyzing data registered in the operation management database and transmitting the bus approach information to the user terminal. This bus approach information transmission process is performed between the operation information transmitting station 40 and the user terminal 50.

First, the bus user executes predetermined Internet browsing software on the user terminal 50 owned by the bus user so that the user can browse the Internet. When the Internet browsing is enabled, the user uses the user terminal 50 to operate the Internet 20 by the operation information transmitting station 40.
Then, the user accesses the bus operation guide menu page provided on the server 0 and requests a bus stop information menu of a desired area (step S41). When receiving the bus stop information menu transmission request from the user terminal 50, the operation information transmitting station 40 transmits the bus stop information of the requested area to the user terminal 50 (step S42). The transmitted bus stop information of the requested area is displayed on the screen of the user terminal 50.

When the bus stop information of the requested area is displayed on the screen, the user selects a desired bus stop on the user terminal 50 and requests bus approach information (including traffic congestion information) at the bus stop. (Step S43). Upon receiving the bus access information transmission request from the user terminal 50, the operation information transmitting station 40 searches the operation management database for a bus approaching the requested bus stop, and considers the current position of the bus and traffic congestion information. The estimated arrival time is transmitted as bus approach information to the user terminal 50 (step S44). The transmitted bus approach information is displayed on the screen of the user terminal 50.

The operation information transmitting station 40 is connected to the Internet 20
The information that can be provided to the user terminal via the "0" includes, in addition to the bus approach information, the time required to reach the destination specified by the user, as well as map information and town information near the bus stop. When providing the estimated arrival time of each bus stop, it is necessary to register the position of each bus stop, and when providing the required time to the destination, register the timetable of each bus stop in the operation management database. When providing map information or town information near a bus stop, it is necessary to register such information in an operation management database.

As an example, a description will be given of a processing flow when providing a required time to a destination. Step S4 described above
Subsequent to 4, the user inputs the bus stop of the final destination on the user terminal 50 and requests the calculation of the required time to the destination. When the required time to the destination is requested, the operation information transmitting station 40 changes the bus stop (riding bus stop) selected in step S43 to the final destination bus stop (disembarking bus stop).
Approximate time required is calculated according to the timetable of those bus stops registered in the operation management database. In this calculation, the position information of the bus that has already passed through the boarding bus stop may be searched in the operation management database, and the required time in consideration of traffic congestion and the like may be calculated based on the position information.

The user may input the current location (address) and the final destination (address) of the user on the user terminal 50, and request the required time to reach the destination. In this case, the operation information transmitting station 40 transmits the nearest bus stop (get on) at the current location of the user and the nearest bus stop (get off) at the final destination on the operation management database.
And calculates the required time between the bus stops.

As described above, the user does not need to go to the bus stop to go from his / her own terminal (computer, mobile phone, PHS, etc.) to the bus access information of the desired bus stop, the estimated arrival time, and the final destination. , Etc., can be easily obtained.

As described above, instead of DGPS, the current position of the bus is specified by using position data by single GPS or designated position passage information (pass information of the bus stop position), and the user is notified of the bus approach information and the like. Information such as the time required to reach the destination can also be provided. FIG. 6 shows designated position passage information,
The differences in processing between the single GPS and DGPS modes are shown.

In the case of the designated position passage information, the operator apparatus 30 sets the designated position and the bus identifier, sends them to the operation information transmitting station 40, and registers them in the database. When the bus (mobile) passes the designated position, the position transmitting device 10 transmits the bus identifier and the passing position information, which are the designated position passing information, to the position information collecting station 20. Location information collection station 2
0 specifies the current position of the bus by comparing the passage information collected by the position information collection station 20 with the designated passage position information notified from the operator device 30 in advance.
By doing so, the position measurement device 21 and the position measurement processing unit 22 of the position information collection station 20 become unnecessary, and the DGPS calculation processing (steps S22 and S23) becomes unnecessary.

In the case of the single GPS, the position transmitting device 10 of each bus acquires the current position (latitude / longitude) of the bus based on the received GPS signal, and transmits this to the position information collecting station 20. The operation information transmitting station 40 converts the bus operation route information notified in advance from the operator apparatus 30 into latitude and longitude, and converts the converted latitude and longitude and the latitude and longitude of each bus collected by each position information collection station 20. The current position of the bus is identified by matching with the longitude. Also in this case, the position measurement device 21 and the position measurement processing unit 22 of the position information collection station 20 become unnecessary, and the above-described DGPS calculation processing (step S2)
2, S23) becomes unnecessary. Since the case of GDPS is as described above, the description is omitted here.

Regarding the positioning accuracy of the bus position in the above three modes, DGPS is the highest, followed by single GPS and designated position passing information. In the case of adopting the designated position passage information, for example, in the case of a bus, since information passing through a bus stop or the like is data, it is not possible to provide data smaller than the bus stop passage interval as information provided to the user. Can not. When the single GPS is adopted, the accuracy of the position data by the GPS measurement is 100 m higher than that of the DGPS in the case of a bus running in an urban area.
An error of ~ 200 m occurs.

As described above, the data sent to the operation information transmitting station 40 differs depending on whether the operator apparatus 30 performs the operation management using the GPS information or the passing position management such as the existing bus stop passing information. In the case of GPS information, if there is map data such as a route map, the travel route can be registered in the database by latitude and longitude. In that case, the accuracy differs between the single GPS positioning and the DGPS positioning, and the latitude and longitude points of the route data can be set more finely in the DGPS, and more accurate position information of the moving object can be provided.

(Other Embodiments) If the user terminal 50 is a mobile phone or a PHS, the location of the user can be specified by the position of the base station that has received radio waves from the mobile phone or the PHS. Such a position specifying system is a well-known system, and in this embodiment, the system is used to
The current position of the user is specified, and the nearest bus stop information is transmitted to the user terminal.

First, the bus user executes predetermined Internet browsing software on the user terminal 50 owned by the bus user so that the user can browse the Internet. When the Internet browsing is enabled, the user uses the user terminal 50 to operate the Internet 20 by the operation information transmitting station 40.
Access the bus operation guide menu page provided on 0.

When there is access by the user, the operation information transmitting station 40 obtains the ID number of the connected user terminal 50 from the connection information, and transmits the ID number to the position specifying system. Request the current location of the user.
Then, when the operation information transmitting station 40 acquires the current position of the user from the position specifying system, the operation information transmitting station 40 transmits bus stop information near the current position to the user terminal 50. The transmitted bus stop information is displayed on the screen of the user terminal 50.

When the nearby bus stop information is displayed on the screen, the user selects a desired bus stop on the user terminal 50 and requests bus approach information (including traffic congestion information) at the bus stop. Upon receiving the bus access information transmission request from the user terminal 50, the operation information transmitting station 40 searches the operation management database for a bus approaching the requested bus stop, and considers the current position of the bus and traffic congestion information. The estimated arrival time is transmitted to the user terminal 50 as the bus approach information. The transmitted bus approach information is displayed on the screen of the user terminal 50.

Although the system of each embodiment described above is an example applied to a route bus, the present invention is not limited to the route bus, and the user is provided with the current position of the moving object moving on the fixed route. The present invention can be applied to any guidance system. For example, the present invention can be applied to a system for managing the operation of a garbage truck.

For application to another fixed route mobile object management system, the operator can use the operation information transmitting station 4 from the operator device 30.
This can be easily performed by transmitting data relating to an arbitrary fixed route to “0”. The user can use the position transmitting device 1
From 0, the operation information transmission station 40 can be inquired of the operation information of the fixed route mobile collected through the position information collection station 20 using the user terminal 50. As described above, the operator registers the route information and the time information data of the moving body moving on the fixed route in the operation information transmitting station 40, and installs the position transmitting device 10 on the moving body to move other than the bus. It is possible to provide body information to the user.

[0056]

As described above, according to the present invention,
A mobile user, for example, a bus user, can confirm the bus operation status at any place such as at home, office, or walking, as long as the user can access the Internet. Therefore, when the arrival of the bus is delayed due to traffic congestion, the bus user can go to the bus stop after estimating the arrival time of the bus, and use the valuable time of the bus user effectively. it can.

Further, since traffic congestion information and the time required to reach the destination can be provided, the user can arrive at the destination without delay.

In particular, in the case of a route bus, compared with a transportation system that does not depend much on the operation route conditions such as trains, the bus is often not operated on time due to delays due to traffic congestion, etc. The convenience of the bus is further improved, and as a result, the use of the bus is activated. In addition, by recognizing the use of buses as an effective means of transportation, it is possible to suppress the movement of private cars and company cars, which has the effect of reducing traffic congestion and reducing exhaust gas. Such an effect becomes more remarkable especially in an urban area where there is heavy traffic.
