As for the calculation method of the fare, in the case of a railway, the fare is obtained from the total distance calculated at the time of searching the route. Find the fare near the bus fare from the fare table between each bus stop. Alternatively, in the case of a bus, the fare for the midway use section is calculated based on the fare from the starting station.

The operation of FIGS. 3 and 4 will be described (see FIGS. 5, 6, 7, and 8). In FIG. 4, the GPS information receiving unit 32 measures the current location based on the GPS information from the artificial satellite received by the receiving antenna 32 '. In the normal power-on state, the map information processing unit 72 reads the map of the area from the map file according to the GPS information (latitude and longitude of the current location), processes the current location as a point on the map, and displays it in the display processing unit 43. Pass map data. The obtained map and the current location are displayed on the display 44 by blinking or the like.

In this state, the destination is input by the input device 45 and the input data is passed to the location information conversion section 71. There are two methods for inputting the destination: inputting by address and inputting as points on the displayed map. For example, if you enter Tochigi prefecture, the map around Tochigi prefecture will be enlarged, and if you enter Oyama city, the map around Oyama city will be enlarged and displayed. Next, on the displayed map, select the destination as a point with a cursor and enter the destination. Place information conversion unit 71
Converts the input destination into latitude and longitude and transfers it to the map information processing unit 72.

Next, based on the information on the current location and the information on the destination, the nearest bus stop station search processing unit 74 searches for several bus stops / stations close to the current location / destination from the nearest one and transfers them to the display processing unit 43. To do. The display processing unit 43 displays the received bus stop / station on the display 44 by blinking. Further, the transportation route search unit 75 searches for the route from the nearest bus stop / station searched. This search can be performed with certain conditions. For example, whether to use the Shinkansen or limited express. It is also possible to narrow down the conditions for searching the route by the required time, fare, etc. In this case, the route selecting unit 79 by comparing the time and the fare selects a route according to the input conditions. To do. Alternatively, the user can specify the bus stop / station on the display screen and search the route for the specified station or bus stop. In this way, several routes are searched and the result is transferred to the display processing unit 43. Display processing unit 43
Displays the obtained route by changing the display brightness or blinking it so that it can be seen on the map.

When the route is obtained, each transportation timetable file 105 is opened, the travel time calculation unit 76 calculates the travel time, and the travel time is transferred to the display processing unit 43. Also, at the current time, the next available time is searched at the same time, and the display processing unit 4
Transfer to 3. By inputting the time to arrive at the destination, it is possible to perform a reverse search for what time to leave the current location. Furthermore, once the route to be used is decided, the fare file (106, 107, 10
8, 109, 110), the transportation cost is calculated by the fare calculation unit 77, and the calculated transportation cost is transferred to the display processing unit 43. The display processing unit 43 displays the received data (required time, next boarding time, scheduled departure time, fare, etc.) on the display 44.

Information files (81, 82, 83, 8)
4, 85, 86), the contents will not match the actual contents over time, so the timetables, fares, etc. of the railway companies, bus companies, etc. that manage each data by using personal computer communication etc. are updated. Alternatively, the data is updated using a wireless or wired information service. Alternatively, manually enter data such as timetables.
