TECHNICAL FIELD OF THE INVENTION
The present invention relates to a public transportation operation information distribution system that distributes traffic information to an unspecified number of general users.
[0002]
[Prior art]
Not only public transportation, but also some transportation schedules (operation schedules), the user operates according to the operation schedule (time to arrive at the station or arrives at the destination at a predetermined time) The type of vehicle to be used and the departure time, etc.), so that the current status of transportation (opening of schedules, delay status, expected future transition status, etc.) can be provided to the user or prospective user at the appropriate time. It is extremely important to inform.
[0003]
Conventionally, for this purpose, there is a so-called operation management service system, which is described in detail in Patent Document 1. In the invention of Patent Document 1, for example, the current operation status of a bus is reported to the center (operation management service system) every second in a short period that can be said to be almost real time. Location and speed are known. By accessing the center, the user can know the arrival time of the future bus at the specific station position on the route that he wants to know, the expected arrival time at the specific station when getting on a certain bus, etc. You can save the trouble of having to call the bus company each time.
[0004]
However, since this type of system is an independent system for each transportation company (referred to as a transportation company), for example, in order to use an aircraft at a certain time, the system is installed at a specific bus station near home. If you want to know when to go, not based on the standard timetable, but based on the current bus and aircraft operation status, access to both the airline system and the bus company's system separately If you don't edit the data of your available stations, routes, and time from the unrelated data you obtained There was a problem that data could not be obtained.
[0005]
In addition, most information is collected at arrival and departure times at stations, and it is impossible to obtain similar information at any position between stations.

[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiment 1 FIG.
FIG. 1 shows a system configuration of the traffic operation information distribution system. The transportation network 100 indicates a transportation network of some kind of connection such as domestic, overseas, land, sea, air, etc., connecting to each other. The bus route 101, the city railway line 102, the ferry route 103, the railway line 104, and the air route 105 are moving bodies of a transportation system operated according to a predetermined time schedule (diamond or operation time plan). Each of the transportation means 101 to 105 has an existing operation management system 110 in most cases, though there is a difference in size. In the following description, for convenience of explanation, all moving objects including ships and aircraft will be referred to as vehicles.
[0011]
The operation management system 110 instructs each vehicle to operate each transportation system on a schedule as well as the information of each vehicle, for example, via the existing communication network, the position of the above-mentioned diagram and the position of each vehicle. The information is notified to the collective management system 122 of the traffic information management center 120.
[0012]
This information includes, for example, a business ID number indicating a transportation system to which each vehicle belongs, a route ID for identifying a route, a moving body ID for individually identifying each vehicle, and a current position. The operation data includes operation information (also referred to as operation results) including speed information and congestion status, and is transmitted to the collective management system 122 at a time density of, for example, about one minute. The current position referred to here is, for example, in the case of one-dimensional transportation such as a railway, distance information from a specific position (for example, a terminal station), and in the case of a ship (although the route is predetermined, It is two-dimensional position information (acquired by GPS) because there may be an accident. Since the operation data can be modified and added in various ways, it will be specifically described in each of the following embodiments.
[0013]
The operation data of all vehicles operating on the transportation network 100 is accumulated in the collective management system 122. Thus, in the collective management system 122, at least the schedule of all the operators and all the routes and the current position data of each vehicle are concentrated.
[0014]
The collective management system 122 is connected to the information disclosure system. The information disclosure system is, for example, the Internet or digital broadcasting. The case where the information disclosure system is the Internet is well known and will not be described in detail, but any user can freely access and extract information.
1 and 2, as an example of the information disclosure system, an earth station 121 (referred to as a quasi-zenith satellite broadcasting network 129) that communicates with the communication satellite 130 is installed in the collective management system 122, and operation data of all routes is provided. The figure shows a case in which a collective management system 122 that collectively manages and schedules is installed. Details of the collective management system 122 will be described later.
The quasi-zenith satellite broadcasting network 129 includes a transmitting earth station 123 and a broadcasting satellite 131.
As will be described later, the broadcast wave 200 of the broadcasting satellite 131 can be received by each vehicle and the operation system 110 in the figure and each vehicle such as a general mobile phone (not shown), a general home, a business office, and a terminal. is there.
[0015]
FIG. 2 shows details of the configuration of the traffic operation information distribution system of FIG. The business operation management system 110 is connected to the collective management system 122 by a general communication network 111 capable of two-way communication such as an existing telephone network or the Internet shown in FIG.
The actual operation management unit 122a of the collective management system 122 receives the operation data of each vehicle via the communication network 111, and stores the operation data in the operation result storage unit 122b. The diagram management unit 122c receives the diagram of each business operator via the communication network 111 and stores the diagram in the diagram storage unit 122d. When storing the data, if the format of the data is different for each company or for each vehicle, each management unit unifies and stores the data. The stored data is automatically erased when it reaches a predetermined fixed amount or after a certain period of time, starting from the oldest one.
[0016]
The information processing unit 122e transmits the data read from the storage unit to the communication network 111 or the quasi-zenith each time the data of the schedule is changed, and for the actual operation, at a cycle of about several minutes at the longest. Broadcast nationwide via a satellite broadcast network 129. Of course, for example, on a bus route where there is no bus running at midnight, it is only necessary to broadcast, for example, a flag without a running vehicle during that time.
[0017]
Next, a method of informing the collective management system 122 of the traffic information management center 120 of the current operation information (data) of each vehicle will be described. First, the business operation management system 110 in FIG. 2 grasps the operation state of each vehicle. For example, in the case of a bus, the accuracy of the distance between stops is approximately determined by the stop approach detection system, in the case of a railway, at least the accuracy of the distance between stations or in the accuracy of a preset signal section, and in the case of a ship, a predetermined fixed position notification. Etc. This information is sent to the collective management system 122 via the existing communication network 111 or the like. These are referred to as a first operation information transmission system. That is, the first operation information transmission system includes the business operation management system 110 and the communication network 111. The second operation information transmission system described in the second embodiment may be used instead of the first operation information transmission system.
[0018]
Internet information via the communication network 111 is provided by an operation information search system 140 configured on a personal computer (not shown) of each user, and broadcast waves from the broadcast satellite 130 are received by a receiver (not shown) It is received by the operation information search system 140 owned by the mobile phone, terminal, business office, each vehicle, etc.). Although only one operation information search system 140 is shown in FIG. 2 for convenience of explanation, there are many operation information search systems 140 as described above. The operation information search system 140 receives a broadcast from the broadcast satellite 130 and stores it in the memory 140b. The operation information search system 140 searches for necessary data in the memory 140b according to an instruction (key input) from a user and extracts the extracted data. It has an information search unit 140c that processes the information to make it easier to see and sends it to the information display unit 140d.
[0019]
The user of the operation information search system 140 inputs a desired position (current position or departure position) and a destination position, and a scheduled departure time and a desired arrival time into the information search unit 140c (not shown, but provided with an input device). ). In addition, when a plurality of routes exist between the departure position and the destination position, and a plurality of routes are selected only with the above input information, the route selection information for designating an arbitrary route is provided. (Including a route selection device not shown). The information search unit 140c searches for and displays related operation information data based on the input position information and time information. While the stored operation information data and schedules are data based on the transportation company or route, the data extracted and edited by the information search unit 140c for easy viewing are the position of the user, the time desired to use, the destination The data has been edited based on the data and, of course, is data that spans multiple businesses. Of course, if an operation of viewing unedited data (raw data submitted from each business operator) as it is is possible, it can be viewed as it is.
The communication satellite 130 and the broadcasting satellite 131 may be the same satellite, and the earth station 121 and the transmitting earth station 123 may be the same station.
[0020]
Embodiment 2 FIG.
In the first embodiment, the operation data of each vehicle is described as being transmitted by the first operation information transmission system via the existing business operation management system 110. In the present embodiment, a second operation information transmission system 150 mounted on each vehicle to acquire operation data and transmit the operation data to the center 120 will be described with reference to FIG. Each vehicle is equipped with a second operation information transmission system 150. The second operation information transmission system 150 receives position data of each vehicle itself (one-dimensional, two-dimensional or three-dimensional depending on the type of traffic, or subway traffic) obtained by receiving radio waves from the GPS satellites 149 with the antenna 151. As described above, when it is difficult to receive the GPS radio wave, the current position data obtained from the odometer 152 that can determine its own position on the route) and the positioning unit 150a that obtains speed data as change information thereof are provided. are doing.
[0021]
The memory 150b temporarily stores the position data and the like measured by the positioning unit 150a, and stores the data until an appropriate period of transmission time (preferably about 15 seconds, for example, depending on the speed of the vehicle) is reached. The information processing unit 150d performs processing such as preparing the stored operation data into a predetermined format required by the traffic information management center 120, and then transmits the data to the information transmission unit 150d. The information transmitting unit 150d sends the operation data to the communication satellite 130 every time a predetermined cycle (for example, preferably about 15 seconds to 2 minutes) or a predetermined specific position (for example, a station, a port, a specific branch point) is reached. And send. The communication satellite 130 and the earth station 121 form a quasi-zenith satellite communication network.
The operation data may be the same as that described in the first embodiment, but includes, for example, the following data items. Business name, traffic type (bus, railway, ship, aircraft, etc.), route name, vehicle identification number, vehicle type (express, express, normal), acquisition time of location data, location data (distance from starting point) (Information or latitude and longitude information), speed (including direction) data, and additional information may be added. Here, the additional information is, for example, a congestion state (ride rate), a cause of delay, and the like. Note that it is also possible to use general wireless communication means as communication means.
