Travel history collection system and terminal side device used for it

A travel history collection system comprising a terminal side device and a center side device capable of communicating with the terminal side device, wherein

• the terminal side device includes:
• A) a vehicle travel history acquisition part for acquiring a travel history of a vehicle;
• B) a congestion section detection part for detecting a congestion section of the vehicle based on the travel history;
• C) 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 the center side device,
• C1) the first short-range wireless communication part transmitting the travel history to the center side device via at least one roadside device (C1-R),
• C2) the first wide-range wireless communication part transmitting the travel history to the center side device via a wide-range wireless communication antenna,
• C3) an antenna of the roadside device being closer to the terminal side device than the wide-range wireless communication antenna;
• and
• D) a travel history transmission part for
• D1) 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:
• D2) 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
• D3) the first wide-range wireless communication part
• D3-1) not immediately after the congestion section detection part detects the congestion section
• D3-2) but after the vehicle travels a predetermined distance (Llim) or a predetermined time period (Tlim) after the congestion section detection part detects the congestion section,
• D3-3) when the first short-range wireless communication part is out of the communication range of the at least one roadside device, and
• E) the center side device includes
• E1) a second wide-range wireless communication part and a second short-range wireless communication part for receiving the travel history transmitted from the terminal side device.
