The network data specific to the route bus is used for management, enabling matching processing in specific areas such as sales offices, parking lots, and yards adjacent to bus terminals and service routes, and positioning of the current position in the vehicle The present invention relates to a route bus operation management system and a mobile terminal device capable of accurately matching an error on a route.

  2. Description of the Related Art Conventionally, navigation devices and navigation systems that guide a user by searching for a route from a desired departure point to a destination using map data and road data are known. Such navigation devices and navigation systems are known. As a car navigation device that is installed in a car and guides the route to the driver, a mobile phone is used as a navigation terminal to send a route search request to the route search server, receive the result, and receive route guidance Navigation systems have been put into practical use.

  In particular, the communication-type navigation system is a system that uses a mobile terminal such as a mobile phone as a navigation terminal, and is also used as a navigation system for pedestrians. As a navigation system for pedestrians, it is preferable to add a route guidance function including transportation, and in addition to searching and guidance for walking routes, train time data is stored in a route search server, There is also a navigation system that has a function of guiding a route (boarding candidate train) to a desired destination station in addition to searching and guiding a walking route.

  There is also known a route search system that searches and guides a route from a departure place to a destination using transportation means such as an airplane, a train, a train, and a bus. In general, such a route search system is an operation data DB (in which operation data of each transportation facility is converted into a database on the basis of route search conditions such as departure date and time, departure place, destination and arrival time specified by the user. Database)), each of the available transportation means connecting the departure point and the destination including the connection is sequentially traced as a route, and a candidate of a guidance route (transportation means such as a train) that matches the route search condition is 1 Configured to present one or more. As route search conditions, it is generally possible to specify conditions such as required time, number of transfers, and fares.

  For example, when the road network for route search in the pedestrian navigation system and the car navigation system includes roads A, B, and C as shown in FIG. 7, the end points, intersections, bending points, etc. of the roads A, B, and C The road connecting each node is represented by a directional link, and node data (node latitude / longitude), link data (link number) and link cost (link distance or link travel) of each link The road network data is composed of link cost data using the required time required for data). That is, in FIG. 7, ◯ and ◎ indicate nodes, and ◎ indicates a road intersection. Directional links connecting the nodes are indicated by arrow lines (solid line, dotted line, two-dot chain line). As for the links, there are links facing in the upward and downward directions of the road, but in FIG. 7, only the links in the direction of the arrows are shown for the sake of simplicity.

  When route search is performed using such road network data as a route search database, links linked from the starting node to the destination node are traced to accumulate the link cost, thereby minimizing the accumulated link cost. Search and guide the route. That is, in FIG. 7, when a route search is performed with the departure point as the node AX and the destination as the node CY, the road travels from the node AX along the road A, turns right at the second intersection, enters the road C, and reaches the node CY. The link cost is accumulated sequentially, and a route that minimizes the accumulated link cost is searched for and guided. Although other routes from the node AX to the node CY are not shown in FIG. 7, in reality there are other such routes, so a possible route from the node AX to the node CY is similarly searched. Of these routes, the route with the lowest link cost is determined as the optimum route. This method is performed by, for example, a known method called the Dijkstra method.

  Such a road network is static network data in which the link cost is fixed as schematically shown in FIG. 7 and the accumulated link cost is uniquely determined when the route is determined. The amount of data is also the road network. Is proportional to the amount of. The same applies to the operation network data of the transportation system, and the data of the road network where the bus route is set is used as the data of the route network.

  Currently, there is also a route bus operation management system using such a navigation system. Such an operation management system, for example, installs a mobile terminal on a vehicle on each route bus, measures the current position and performs matching processing on the route network, grasps the operation position of each vehicle, and Is a system that displays a scheduled time of arrival of a vehicle, detects traffic congestion on a road, and manages a history of vehicle allocation and vehicle operation.

  Such route bus operation management systems are disclosed in the following Patent Document 1 (Japanese Patent Laid-Open No. 8-180298) and Patent Document 2 (Japanese Patent Laid-Open No. 2004-227268). That is, Patent Document 1 discloses a moving body approach notification system that detects the current position of a route bus vehicle using a position detection system of an artificial satellite, sends position information wirelessly to a fixed station, and notifies the map information together with an image or sound. Is disclosed. In this system, the mobile unit stores the position information detected by the satellite communication unit and the mobile unit position detection unit in the mobile unit storage unit. When there is a transmission request from the fixed station side, this position information is transmitted by the fixed station communication control means and the fixed station communication means. The fixed station receives this by the mobile communication control means and the mobile communication means and stores it in the location information storage means. The current position of the fixed station is stored in the position information storage means by the fixed station position information input means F, and the map information is stored in the map information storage means. The notification means notifies the position information of the mobile body and the fixed station and the map information.

  Further, in Patent Document 2, even if each region provided on a predetermined route such as a route bus has an overlapping portion, the vehicle enters in a predetermined order in which the vehicle operates on the predetermined route. A position information notification system and a position detection device that accurately notify each area to be disclosed are disclosed. In this system, the position detection device mounted on the bus detects the entry to a predetermined area around each stop set on the predetermined operation route of the bus, and the area number of the area where the entry of the bus is detected is When the area numbers of the areas that have been detected and notified to the computer first are consecutive in ascending order, the next entry of the bus to the detected area is notified to the computer, and the computer enters the area. Notify the mobile phone of the entrance of the bus.

JP-A-8-180298 (FIGS. 1 and 5) JP 2004-227268 A (FIGS. 1 and 4)

  By the way, also in the route bus operation management system, as in a general navigation system, there is an error in the current position measured by a position detection means such as a GPS receiver in each vehicle. Normally, this error is about 10 m when the GPS satellite signal reception state is good, and this error further expands in places with poor reception conditions such as buildings. In order to correct this error, if the current position measured is out of the road or guide route of the map data, matching is performed on the road or guide route that is closest to the current position, and so-called matching processing is performed to reduce the positioning error. It has been corrected. The process of matching the measured current position on the road of the map data is called a map matching process, and the process of matching on the guide route is called a route matching process.

  However, the position information notification system disclosed in Patent Document 1 and Patent Document 2 detects the current position of each vehicle operating on a route and guides it to a stop or a mobile phone. There is no disclosure about correcting the current position error. Although the general map matching process or the route matching process described above can be applied to the operation management system such as Patent Document 1 and Patent Document 2, the following problems are encountered in the route bus: Occurs.

  First, in a route bus operation management system, unlike a general vehicle-mounted navigation system, remote management is performed by an operation management server, so that a map matching error is not noticed. In particular, an acute Y-shaped road (a branch road in which the road branches at a small angle) is likely to cause an error that matches in the reverse direction (the road that is not the route). If such an error occurs, the location of each vehicle (bus) is managed by the operation management server, so that the correct road cannot be found without noticing the matching error until the bus has traveled to some extent. Problems arise.

  Second, in the route buses, the main terminals are often adjacent to railway stations, etc., and buildings are densely located in front of the stations, and GPS satellite radio waves are affected by multipath, so there is a positional error. There is a problem of growing. In addition, since a general car is prohibited from entering the bus terminal, there is a problem that a general electronic map for car navigation has no node or link setting, and map matching of the vehicle position cannot be performed.

  Thirdly, the bus offices, parking lots, and yards often face the business routes, and they match the roads and routes even though they are on the premises of the sales offices, parking lots, and yards. In some cases, it is confusing whether the vehicle is waiting or operating. In the route bus operation management server, the operation history of each vehicle is also kept and the operation management is performed. Therefore, the above-mentioned matching error may become a problem later.

  As a result of various studies to solve the above problems, the inventor of the present application determines that the road network data for displaying the route is only the route network data, and the route network data includes the terminal and the sales office. It is conceived that the above problems can be solved by appropriately controlling the matching process in a specific area by adding position data of a specific area such as a parking lot and a yard, and route network data in the specific area. The present invention has been completed.

  That is, the present invention has an object to solve the above-mentioned problems.

The invention according to claim 6 of the present application is the invention according to claim 4 or 5 , wherein the route network data is data of a route network of a route on which the vehicle is operated.

  Hereinafter, specific examples of the present invention will be described in detail with reference to examples and drawings. FIG. 1 is a block diagram showing a configuration of a route bus operation management system according to an embodiment of the present invention. FIG. 2 is a schematic diagram for explaining a matching process for matching the current position of the vehicle with the road of the map data. FIG. 3 is a schematic diagram for explaining the matching process in the present invention. FIG. 4 is a schematic diagram for explaining a matching process according to an embodiment of the present invention in a specific area such as a bus terminal. FIG. 5 is a schematic diagram for explaining matching processing in specific areas such as a business office, a parking lot, and an operation area. FIG. 6 is a flowchart showing the procedure of the matching processing operation of the mobile terminal device according to the embodiment of the present invention.

  As shown in FIG. 1, a route bus operation management system 10 according to a first embodiment of the present invention is a device connected to an operation management server 30 via a wireless network 12 and mounted on each vehicle. The apparatus 20 is comprised. The wireless network 12 may be a dedicated network or may be configured to use the Internet network.

  The mobile terminal device 20 includes a control unit 21, a position detection unit 22 including a GPS receiver, an autonomous navigation unit 23 that detects the vehicle position from the distance sensor 231 and the gyro 232, a matching unit 24, a communication unit 25, The area determination means 26 for determining whether the current position is in a specific area, which will be described later, the route data storage means 27 for storing route data of the route bus, the mobile terminal device 20, and the route of the route are displayed. Operation / display means 28 and the like. The communication means 25 is an interface for communicating with the operation management server 30 via the network 12. The communication means 25 is not particularly limited, but a mobile phone or a PHS (registered trademark) data line interface is easy to use.

  Although not shown, the control unit 21 is a microprocessor having a RAM, a ROM, and a processor, and controls the operation of each unit by a control program stored in the ROM. The position detection means 22 receives a signal from a GPS satellite as in a normal navigation device, calculates the position (latitude, longitude) of the mobile terminal device 20 and detects the current position. On the other hand, the autonomous navigation means 23 is a means for detecting a position when the position of the position detection means 22 cannot be detected by GPS, and is a distance for detecting a vehicle speed pulse and calculating a travel distance in the same manner as a normal vehicle-mounted navigation device. The current position of the host vehicle is detected from each sensor output of the gyro 232 such as the sensor 231 and the rate sensor (angular velocity sensor).

  The matching means 24 performs a matching process on the road or route with the current position detected by the position detection means 22 or the autonomous navigation means 23 in the general navigation device described above. The location information of the route bus can be transmitted to the bus company operation management server 30 via the communication means 25. In the present embodiment, only the data stored in the route data storage means 27, that is, the data of the road network of the route on which the route bus is operated, is converted into data as nodes, links, and link costs as in the road network shown in FIG. Route network data. The route network data stored in the route data storage means 27 may be downloaded from the operation management server 30 or copied using a storage medium such as a memory stick. The route network data stored in the route data storage means 27 may be only the data of the business route for each sales office, or may be only the data of the route on which the vehicle operates on that day.

  In general car navigation systems, map drawing data is also stored on a DVD (registered trademark), CD-ROM, or HDD, but the mobile terminal device 20 mounted on a vehicle such as a route bus according to the present invention has a compact flash (registered trademark). ) A storage capacity of about is sufficient. Since there is no need to display a map in a car on a route bus, map drawing data need not be stored. Also, as mentioned above, there is a possibility that the route bus may travel, that is, it is enough to memorize all routes of the bus company, and a compact flash is prepared for each route data to be operated. , You may replace it.

  As described above, the route network data need not store all the data of the general road network. Rather, it may be more convenient as will be described later if there is no road data that is not a route among a plurality of adjacent roads. That is, by storing only the data of the route network in the route data storage means 27, the data of the road where the bus route is not set is not included, so that the matching means is not a route in an acute branch as will be described later. There is no risk of accidentally matching the road.

  On the other hand, the operation management server 30 includes a control unit 31, operation management means 33, communication means 35, route network DB (database) 37, road network DB (database) 36, operation / display means route guidance means 38, and the like. Has been. Although not shown, the control unit 31 is a microprocessor including a memory such as a RAM and a ROM, and a processor, and controls the operation of each unit by a control program stored in the memory. The operation / display means 38 operates the operation management server 30 and performs display for monitoring the state of the operation management server 30. The communication unit 35 is an interface for communicating with the mobile band terminal device 20 and the like via the network 12.

  The operation management means 33 stores the operation history of each vehicle, and the scheduled time to arrive at each stop based on the information on the current position subjected to the matching process from the mobile terminal device 20 mounted on each vehicle. Or notify. The road network DB 36 stores road network data (nodes, links, link costs) in a normal navigation system. In the present invention, the data of the road network DB 36 is not necessarily an essential element. The route network DB 37 is a database that stores only the data of the road network in which the route is set as described above. In this embodiment, the route network DB 37 is a route of a route on which a vehicle is scheduled to travel in a specific area described later. Data such as nodes, links, and link costs are added. For example, the area of the bus terminal in front of the station is an area where general vehicles are prohibited from entering, and thus does not exist in the data stored in the road network DB 36. However, the route network DB 37 has a specific specification specific to such a bus route. Route data within the area is added.

  In the route bus operation management system 10 according to the first embodiment, as described above, by storing only the route network data in the route data storage means 27, the data of the road where the bus route is not set is stored. Since it is not included, there is no possibility that the matching unit erroneously performs matching processing on a road that is not a route on an acute branch road. FIG. 2 is a diagram schematically illustrating a case where the current position measured by the mobile terminal device 20 is subjected to matching processing on a road of map data.

  In FIG. 2, a road 211 branches at an acute angle into a road 213 where a bus route is not set at a node (branch point) 212 and a road 214 where a bus route is set. FIG. 2 shows a problem that occurs when such a sharp Y-junction passes through GPS navigation, that is, a GPS satellite signal is received and the current position is measured. The bus route is set to the road 214 that branches the Y-shaped road to the right, and the bus is running on this road 214, but the position information ◎ obtained by GPS was slightly shifted to the left, When matching is performed, a matching process is mistakenly performed at the position on the left side (indicated by Δ in FIG. 2), and the road 213 is erroneously recognized. This state is sent to the operation management server 30. Since the server 30 remotely manages the bus, the server 30 does not notice the matching error until the bus has traveled to some extent, and cannot match the correct path.

  Here, as the road network data stored in the route data storage means 27, only the route bus route network data excluding the network data of the road 213 for which no bus route is set is stored in FIG. As shown, since the road data to be matched is only the data of the road 214 on which the bus route is set, even if the positioning position on the bus has an error in the direction of the road 213, the road 214 is correctly Matching process is performed. If another bus route is set on the road 213, a different compact flash is replaced for each bus operating on the corresponding bus route, or route network data for each route operated from the operation management server 30 Can be covered in terms of operation, such as downloading.

  As described above, the route network DB 37 is a database that stores only the data of the road network on which the route is set. In this embodiment, the route network DB 37 is a node of the route on which the vehicle is scheduled to travel in the specific area. Data such as link and link cost are added. That is, since the area of the bus terminal in front of the station is an area where general vehicles are prohibited from entering, there are no nodes or links in the area in the data stored in the general road network DB 36, but the route network DB 37 Route data in a specific area specific to such a bus route is added.

  FIG. 4 schematically shows a link in an area where a bus terminal such as a train station is a specific area. An area surrounded by a broken line 311 is a bus terminal area where general vehicles are prohibited from entering. Among these, the link 312 in the broken line 311 and the links 313 to 315 in contact with the broken line 311 are links that are not in the map of a general car navigation system. Because this part is a passage dedicated to the route bus, and a section in the temporary shelter that is not a passage is also represented by a link. Further, the location information of the area of the bus terminal indicated by the broken line 311 is also stored in the route network DB 37 together with the route data.

  As described above, there are many buildings around the railway station, and GPS positioning tends to have a large error due to the influence of multipath. Therefore, when a bus enters the terminal area, a matching error is likely to occur. Therefore, if it is determined that the bus position of the bus has entered the bus terminal indicated by the broken line 311 in FIG. 4, the processing of the matching means 24 is switched to matching processing as a terminal area. That is, the GPS can still be used at the moment of entering the boundary, but in the terminal area, the influence of multipath is large or the GPS cannot be received, so switching to the current position positioning by the autonomous navigation means 23 is performed.

  Even in the positioning by the autonomous navigation means 23, the bus behavior is determined in the terminal area 311. Therefore, by matching to the link of the route network in the specific area added to the route network DB 37, the accurate position can be obtained. Recognize. The current position data of the bus subjected to the matching process is sequentially transmitted to the operation management server 30. Since the link in the terminal area 311 extends to the outside of the terminal area, if the current position of the bus is determined to be outside the terminal area as a result of the matching process, the positioning of the current position by this autonomous navigation and the mode of the matching process are finish.

  In addition to the above terminals, there are sales offices, parking lots, and yards as specific areas where routes bus vehicles may be located (routes that do not exist in general road network data are set) . Such an area often faces the bus sales route, and even though the vehicle is in the area of the business office, parking lot, and yard, the mobile terminal device 20 mounted on the vehicle There is an error in the current position of the measured vehicle, and it may be matched with the road of the road network or the route network in contact with the site of the sales office, parking lot, or yard. If there is an error in such matching processing, it cannot be determined whether the vehicle is on standby or in operation, and operation management in the operation management server 30 becomes difficult.

  FIG. 5 is a schematic diagram for explaining the matching process in the case where the site of such a business office, a parking lot, and a yard is used as the specific area 411. Since such a specific area 411 requires a large parking lot, it is located in a relatively suburb and is easy to receive GPS signals. Further, since it is inefficient to move away from the operation route, it is often located facing the operation route 412, the road 414, and the like. Furthermore, since 413 in a specific area such as a business office is a private property of a bus company, the use of the section is free, and a specific link cannot be laid. Therefore, when parking along a road in a business office, the matching with the operation road 412 or the road 414 adjacent to the specific area is caused by a positioning error by GPS.

  For this reason, in this embodiment, when the intrusion of the bus into the sales office area 411 is detected, the position is obtained by utilizing GPS or autonomous navigation, but the matching means 24 does not perform the matching process. (Do not set network data, ie nodes or links). Instead, an accurate position can be obtained by performing a process of predicting the current position and adopting only a highly reliable positioning result from the predicted position range. Such a technique can be performed by applying the technique disclosed in Japanese Patent Application Laid-Open No. 2004-271293 filed by the present applicant. In this way, for example, even if there is an error in GPS positioning, it is possible to prevent a matching processing error that suddenly matches a link (road) outside the sales office.

  It should be noted that such a specific area 411 may technically be measured by either GPS or autonomous navigation, but the fact that the vehicle has returned to a specific area such as a sales office is a mobile terminal mounted on the vehicle. Since it is assumed that the power of the device 20 is turned off (off), it is necessary to pay attention to the handling until the next power-on in the autonomous navigation using the relative position. For example, if the mobile terminal device 20 is moved with the power off for inspection and maintenance, the autonomous navigation will have the wrong position. Therefore, it can be said that it is easier to use GPS positioning for matching processing in such an area.

  Next, with reference to the flowchart of FIG. 6, the procedure of the matching process in the mobile terminal device 20 according to the embodiment of the present invention will be described. First, the mobile terminal device 20 measures the current position of the own vehicle by the position detection means 22 or the autonomous navigation means 23 in the process of step S10. Next, in the process of step S11, the area determination unit 26 determines whether or not the current position is in the specific area. As a result, when the current position of the vehicle is in an area on a normal route that is not a specific area, that is, in area A, the current position is determined by the position detecting means 22 using GPS in the process of step S22, and in the process of step S23. The matching unit 24 performs a normal matching process.

  In this case, as described in the first embodiment, only the route network data is stored in the route data storage means 27 and does not include the data of the road where the bus route is not set. In this case, there is no possibility that the matching means erroneously performs matching processing on a road that is not a route.

  As a result of the area determination in step S11, if the current position of the vehicle is in a specific area that is a bus terminal in front of the station, that is, area B, the current position is determined by the autonomous navigation means 23 in the process of step S32, and step S33 In this process, the matching means 24 performs the matching process using the network data in the specific area.

  In this case, as described in the second embodiment, since the network data is added only to the route bus in the specific area to the route network data in the route data storage unit 27, the matching process can be performed. Further, since positioning is performed by the autonomous navigation means 23, accurate positioning can be performed using positioning that is not affected by multipath in GPS positioning.

  If the current position of the vehicle is in a specific area such as a sales office, that is, area C as a result of the area determination in step S11, the current position positioning by the position detection means 22 or the autonomous navigation means 23 by GPS is performed in the process of step S12. I do. In this case, preferably, positioning by the position detecting means 26 by GPS is performed. In the process of step S13, the matching unit 24 does not perform the matching process, but performs the current position process using the reliability filter described in the third embodiment.

  Next, the mobile terminal device 20 performs step S11, step S12 processing, step S22, step S23 processing, step S32, step S33, and current position data obtained by correcting the positioning error. In the process of S <b> 14, the information is transmitted to the operation management server 30 via the communication unit 25. Next, in the process of step S15, it is detected whether or not the power of the mobile terminal device 30 is turned off. If the power is not turned off, the process returns to the process of step S10 and the processes described above are repeated. If the power is off, the mobile terminal device 20 ends the process.

  As described above, according to the route bus operation management system, the operation management server, and the mobile terminal device according to the present invention, the current position error in the mobile terminal device mounted on the vehicle is accurately matched to the data of the route network. Therefore, it is possible to provide a route bus operation management system that can correctly determine the position of the vehicle in the operation management server.
