  The optical disk drive 306 controls the reading / writing of the data with respect to the optical disk 307 according to control of CPU301. The optical disk 307 is a detachable recording medium from which data is read according to the control of the optical disk drive 306. As the optical disc 307, a writable recording medium can be used. In addition to the optical disk 307, the removable recording medium may be an MO, a memory card, or the like.

  One example of information recorded on the magnetic disk 305 or the optical disk 307 is map data used for route search / route guidance. The map data includes background data representing features (features) such as buildings, rivers, and the ground surface, and road shape data representing the shape of the road. The map data can be displayed two-dimensionally or three-dimensionally on the display screen of the display 314. Drawn. When the navigation device 300 is guiding a route, the map data and the current location of the vehicle acquired by the GPS unit 316 described later are displayed in an overlapping manner.

  The audio I / F 308 is connected to a microphone 309 for audio input and a speaker 310 for audio output. The sound received by the microphone 309 is A / D converted in the sound I / F 308.

(Route guidance processing by the navigation device 300)
Next, route guidance processing by the navigation device 300 will be described. As described above, the navigation device 300 receives almost real-time road traffic information and train operation information through the communication I / F 315. By using these pieces of information, the navigation apparatus 300 can perform route guidance reflecting actual road conditions. In particular, by using train operation information, it is possible to avoid a traffic jam at a crossing and select a route that is easier to travel.

  4 and 5 are flowcharts showing a procedure of route guidance processing by the navigation device. In the flowchart of FIG. 4, the CPU 301 of the navigation device 300 first searches for a route to the destination point set by the user and determines a travel route (step S401). In determining the travel route, for example, the CPU 301 searches a plurality of routes to the destination point and causes the user to select one of the routes as the travel route.

  Next, the CPU 301 waits until the user starts traveling of the vehicle (step S402: No loop), and starts traveling (step S402: Yes), the CPU 301 receives the GPS information received by the GPS unit 316, The current position of the vehicle is calculated using output values output from the various sensors 317, and the calculated current position is displayed on the map data displayed on the display 314 (step S403).

  Next, CPU301 produces | generates and outputs the guidance information along a driving | running route using the road traffic information etc. which were received by communication I / F315 (step S404). The guidance information is an instruction of a traveling direction along the travel route. Further, the guidance information is output by voice output from the speaker 310, display output on the display 314, or the like.

  Subsequently, the CPU 301 determines whether or not the current train operation information has been received by the communication I / F 315 (step S405). When the current train operation information is received (step S405: Yes), the current position of the train is displayed on the map data displayed on the display 314 (step S406). On the other hand, when not receiving the present train operation information (step S405: No), it transfers to step S407.

  Furthermore, the CPU 301 determines whether or not past train operation information can be acquired (step S407). When the past train operation information can be acquired (step S407: Yes), the past train operation information is acquired (step S408), and the process proceeds to step S409 in FIG. On the other hand, when the past train operation information cannot be acquired (step S407: No), the process directly proceeds to step S409 in FIG. For example, past train operation information may be received by a distribution server that is a distribution source of train operation information, or past train operation information is recorded on the magnetic disk 305 and the optical disk 307 of the navigation device 300. You may keep it.

  Moving to the description of FIG. 5, the CPU 301 predicts the open / close state of the crossing on the travel route using the current train operation information received in step S405 and the past train operation information acquired in step S408 (step S409). . Then, the open / close state of the railroad crossing is displayed on the map data displayed on the display 314 (step S410).

  At this time, the level crossings for predicting and displaying the open / closed state may be all level crossings on the travel route of the vehicle, or may be level crossings within a predetermined distance from the current position of the vehicle. If the current train operation information received in step S405 includes information on the open / close state of each level crossing, no prediction is performed in step S409, and the open / close state included in the received information is displayed.

  In addition, if both current train operation information and past train operation information can be acquired, the information on both types of information may be used to predict the open / close state of a railroad crossing, or only one of them may be used for prediction. May be. Furthermore, when neither the current train operation information nor the past train operation information can be acquired, step S409 and step S410 are omitted.

  Subsequently, the CPU 301 determines whether or not to search for another route based on the open / close state of the railroad crossing predicted in step S409 (step S411). For example, the CPU 301 determines whether or not a crossing on the route is closed for a predetermined time or more. Further, the user may determine whether or not to search for another route by looking at the open / close state of the railroad crossing displayed in step S410.

  When searching for another route (step S411: Yes), the CPU 301 searches for another route and displays it on the display 314 (step S412). Then, the CPU 301 determines whether or not to travel on another route (step S413). Specifically, the user determines whether to travel on another route by looking at the other route displayed in step S412. In addition, when it is not possible to search for a route having a merit such as time reduction as compared with the current travel route, the route may not be displayed. The determination of whether or not to display a route may take into account priority items (charge priority, charge priority, trunk priority, etc.) set by the user for route search.

  When traveling on another route (step S413: Yes), route guidance is started along another route (step S414). On the other hand, when the vehicle does not travel on another route (step S413: No), route guidance along the current travel route is continued (step S415).

  Then, until traveling ends (step S416: No), the process returns to step S403 and the subsequent processing is continued. When the travel is finished (step S416: Yes), the processing according to this flowchart is finished.

  FIG. 6 is an explanatory diagram illustrating an example of a train operation information display screen. In FIG. 6, a current position display P indicating the current position of the vehicle is displayed on the display 314 of the navigation device 300. Two roads L1 and L2 intersect the road R on which the vehicle travels, and railroad crossings C1 and C2 are provided at the respective intersections.

  Trains T1 and T2 are moving on the tracks L1 and L2, respectively. The current positions of the trains T1 and T2 are displayed almost in real time, and it is possible to know whether the train is approaching the railroad crossings C1 and C2 on the route. The display 314 also displays the open / closed state of the railroad crossings C1 and C2. In the illustrated example, the train T1 is approaching the level crossing C1, and the level crossing C1 is in a closed state. On the other hand, the railroad crossing C2 is in a state where the train T2 passes and the railroad crossing C2 is open.

  The respective operation information M1, M2 is displayed on each train T1, T2. The operation information M1, M2 displays the estimated arrival time at the next station or main station, the number of passengers, and the like. In addition, for example, the estimated time of arrival at each level crossing, the accumulated traveling time, the delay state from the normal time diagram, and the like may be displayed.

  For example, the navigation device 300 can obtain information on the open / close state of the level crossings C1 and C2, thereby avoiding traffic jams caused by the open / close of the level crossings and searching for a route that can reach the destination without stress. In addition, by displaying the current positions of the trains T1 and T2 in almost real time, it is possible to prevent waste of time and mistakes when picking up the train station or when train enthusiasts take pictures of the train. be able to.

  Further, for example, by displaying the number of passengers and the passenger rate of the trains T1 and T2, an approximate number of passengers at the station can be grasped. As a result, it is possible to grasp the expected number of customers acquired by a taxi company or the like, which can be used for dispatching taxi vehicles.

  In this embodiment, the operation status of the train is set as the operation status of the transportation facility. However, the present invention is not limited to this. For example, the same processing may be performed using the operation status of an airplane, a ferry, a bus, or the like.

  As described above, according to the navigation device 300, in addition to the current position information of the vehicle and the road traffic information, information on the transportation system that operates around the travel route of the vehicle, specifically, the operation status of the train is displayed in real time. indicate. Thereby, the operation status of the trains that run around the vehicle can be displayed in real time together with the movement status of the vehicle, and the travel route of the vehicle can be determined with reference to the operation status of the train.

  Specifically, for example, it is possible to select a route that is easier to travel, such as determining whether to select a route with a railroad crossing based on the current location of a train around the current location of the vehicle. It is also possible to reduce waiting times such as picking up passengers on the train and waiting for taxis.

  Moreover, according to the navigation apparatus 300, the open / close state of a railroad crossing predicted from the current position of the train is displayed. Thereby, the situation of the surrounding road can be known in detail, and the travel route can be easily selected. Furthermore, by predicting the open / closed state of the railroad crossing using information on the past operation status of the train, the prediction accuracy of the open / closed state of the railroad crossing can be improved.

  The information display method described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer.
