2, an external input unit 103, an external output unit 104, a traffic information input unit 107, a central control unit 105, and a control bus 106 for connecting these units 101 to 104.

The map information database 101 stores map information for performing a route search. Memory 1
02 is a program for performing route search and fee prediction,
The work area of the central control unit 105 is stored.

The external input unit 103 is connected to another device, and inputs a start position and an end position of the route search. The external output unit 104 outputs a fee prediction result of a speaker, a display, or the like.

The traffic information input unit 107 obtains traffic information from VICS or the like. The central control unit 105
It controls each of the units 101 to 104.

The operation of the fare prediction process performed by the taxi usage fee prediction device 100 having the above-described configuration will be described with reference to a flowchart shown in FIG.

First, in ST201, the boarding point, destination point, and boarding time for estimating the fare are input to the external input unit 1.
Enter from 03. In ST202, a route from the start point to the destination point is searched. This route search uses a route already used in a car navigation device or the like.

In ST 203, traffic information relating to the searched route is input from traffic information input section 107.

Next, fare prediction is performed from the route information and traffic information obtained so far. Taxi fares often consist of two fare systems: a distance-based fare and a time-distance combined fare. Here, a charge prediction method will be described using a general charge system in Tokyo as an example.

First, in ST204, a fare based on the distance fare is calculated. For example, the distance-based fare for a medium-sized car is as shown in FIG.

Assuming that the total distance of the searched route is α, the fare based on the distance fare is calculated as follows.

Α <2km Distance fee = ¥ 660 α>
2km Distance fee = ABSＡ (α-2km) / 274
m｝ × 80 + 660 (yen) Next, in ST205, a fee based on the time-distance combined fare is calculated.

Since the time-distance combined fare is applied when traveling at a speed of 10 km / h or less, the traffic speed of 10 km / h or less and the transit time are extracted from the traffic information obtained in ST203. The transit time for a section distance of 10 km / h or less is β
Then, the fee based on the time-distance combination system is calculated as follows.

Time-distance combined fee = ABS (β / 10
(0 second) × 80 (yen) Next, in ST206, an extra charge based on time is calculated.

When the time is from 23:00 to 5:00, (distance fee + time distance combined fee) × 1.3.

Next, various discounts are calculated in ST207. Since there are types of discounts as shown in FIG. 3,
The correction for the fee discount is made in the following manner.

(Distance fee + time distance combined fee)> 9
In the case of 000, γ = (distance-based fee + time-distance combined-use fee) × 0.9.

In the case of the disabled person discount, the usage fee =
γ × 0.9.

If there are a plurality of search routes, ST203 to ST207 are executed for each of them, and ST208 is executed.
Predict the charge for each route. Subsequently, the usage fee calculated in this way is output from the external output unit 104 in ST209, and the process ends.

As described above, according to the taxi usage fee prediction device 100 of the first embodiment, by inputting the boarding point and the destination point, it is possible to predict the usage fee according to the traffic conditions at that time. .
