Abstract
A travel history collection system includes a terminal side device and a center side device capable of communicating with the terminal device. The terminal device includes the following components. A vehicle information acquisition part acquires a travel history of a vehicle. A short-range wireless communication means and a wide-range wireless communication means are used to transmit the acquired travel history to a center device. A travel history transmission part transmits the travel history to the center device via the short-range wireless communication means when the travel history can be transmitted via the short-range wireless communication means, and via the wide-range wireless communication means when the travel history cannot be transmitted via the short-range wireless communication means. The center device receives the travel history from the terminal device via the wide-range wireless communication antenna and the road side unit so as to reduce the load on wide-range wireless communication, and to accurately collect a travel history from each terminal device at real time. Thus, latest travel histories can be collected efficiently.

12. A terminal side device comprising:
-
a vehicle travel history acquisition part for acquiring a travel history of a vehicle; a congestion section detection part for detecting a congestion section of the vehicle based on the travel history; a first short-range wireless communication part and a first wide-range wireless communication part for transmitting the travel history containing the congestion section to a center side device, the first short-range wireless communication part transmitting the travel history to the center side device via at least one roadside device, the first wide-range wireless communication part transmitting the travel history to the center side device via a wide-range wireless communication antenna, an antenna of the roadside device being closer to the terminal side device than the wide-range wireless communication antenna; and a travel history transmission part for determining whether the travel history can be transmitted to the center side device via the first short-range wireless communication part based on a travel distance and/or a travel time period of the vehicle, and transmitting the travel history to the center side device via;
1) the first short-range wireless communication part when the first short-range wireless communication part is within a communication range of the at least one roadside device and
2) the first wide-range wireless communication part not immediately after the congestion section detection part detects the congestion section but after the vehicle travels a predetermined distance or a predetermined time period after the congestion section detection part detects the congestion section, when the first short-range wireless communication part is out of the communication range of the at least one roadside device. - View Dependent Claims (13, 14)
