The management device 12 communicates with, for example, another server via a network and acquires traffic information regarding traffic conditions from the server.

The management device 12 collects probe data transmitted from the vehicle 11 .

The vehicle 11 is, for example, an automobile having a probe function, such as a private car, a commercial vehicle owned by a corporation, a taxi, a bus, or the like. The vehicle 11 may be a vehicle used for ride sharing.

The vehicle 11 travels on a road on which other vehicles that do not have a probe function also travel, while repeatedly stopping and starting. At this time, the vehicle 11 transmits to the management device 12, for example, travel data including its own position and the time corresponding to the position, accident information, traffic congestion information, construction schedule information, and the like.

More specifically, vehicle 11 can receive radio waves transmitted from, for example, GPS (Global Positioning System) satellites, and can calculate vehicle coordinates indicating its own position based on the received radio waves. be. Here, the vehicle coordinates include latitude and longitude indicating the position of the vehicle 11, for example.

For example, the vehicle 11 calculates vehicle coordinates according to a predetermined sampling timing, and obtains the timing at which the vehicle coordinates are calculated as the time when the vehicle 11 was present at the position indicated by the vehicle coordinates.

That is, the vehicle 11 generates, for example, travel data including vehicle coordinates and the time at each sampling timing. Here, the sampling timing may occur, for example, at a predetermined cycle, or may occur for each event such as stopping, starting, turning on the blinker, after a predetermined time has elapsed since starting, or after running a predetermined distance after starting. .

For example, when generating the travel data, the vehicle 11 generates travel information including the generated travel data and a vehicle ID, which is its own identifier, and transmits the generated travel information to the management device 12 as probe data.

For example, vehicle 11 transmits travel information to management device 12 using a wireless terminal device such as a mobile phone and a smart phone.

FIG. 3 is a diagram showing an example of multiple travel routes calculated by the management device in the data collection system according to the first embodiment of the present invention.

Referring to FIG. 3, route calculation unit 23 calculates a route R1, which is a travel route that does not pass through point C, when the vehicle coordinates are point A and the destination coordinates are point B, for example.

Further, the route calculation unit 23 calculates a plurality of travel routes from the point A to the point B via the point C. FIG. For example, the route calculation unit 23 calculates a route R2 and a route R3 as travel routes from the point A to the point C. As shown in FIG. Route R2 requires a shorter required time than route R3.

Further, the route calculation unit 23 calculates a route R4 and a route R5 as travel routes from the point C to the point B. As shown in FIG. Route R4 requires a shorter required time than route R5.

For example, the price calculation unit 25 calculates a price larger than the price for traveling the route R2 and the route R4 as the price for traveling the route R1 shown in FIG.

The notification unit 24 adds each price information received from the price calculation unit 25 to the corresponding travel route received from the route calculation unit 23 and transmits the information to the vehicle 11 .

Specifically, management device 12 uses, for example, an ITS radio to transmit a plurality of travel routes to which price information is attached to vehicle 11 .

The vehicle 11 presents the received plurality of travel routes to the passenger using, for example, a car navigation display provided therein.

The passenger of the vehicle 11 comprehensively judges, for example, time, cost, consideration, etc., and selects one traveling route from the plurality of presented traveling routes. Note that the cost includes tolls, fuel consumption, and the like.

The vehicle 11 travels along the selected travel route and collects probe data. Then, the passenger of the vehicle 11 receives the price according to the price information, for example, at the destination.

The payment is made, for example, by discounting charges, giving points that can be exchanged for services or products, or the like.

Specifically, for example, when the vehicle 11 travels along the route R1 shown in FIG. , and the passenger of the vehicle 11 is presented with a discounted amount.

The route calculation unit 23 may be configured to calculate a route giving priority to other conditions. In this case, for example, the route calculation unit 23 calculates a route that gives priority to the degree of demand after giving priority to the required time, instead of giving priority to the degree of demand.

More specifically, for example, the vehicle 11 quantifies the required time, cost, consideration, etc. of each of the received plurality of travel routes, and multiplies the reciprocal of the numerical value corresponding to each of the required time and cost by a coefficient. The total value of the value and the value obtained by multiplying the value corresponding to the consideration by the coefficient is calculated for each travel route. Then, the vehicle 11 presents each travel route to the passenger of the vehicle 11 in descending order of the calculated total value.

A passenger of the vehicle 11 selects which of the required time, cost, consideration, etc. should be prioritized. The vehicle 11 determines each coefficient in the above weighting according to the selection result of the passenger of the vehicle 11 .

For example, when priority is given to the required time, the passengers of the vehicle 11 can preferentially receive presentation of a travel route that gives priority to the required time because a large coefficient is set by which the required time is multiplied.

In addition, when the passenger of the vehicle 11 gives priority to the price, for example, a large coefficient is set by which the price is multiplied.
