Abstract
The information transmission control device according to the present disclosure is for controlling a position to start transmitting probe data to a server; the information transmission control device uses a vehicle's current lane segment information and history information about the vehicle's having transmitted probe data, to set a transmission interval distance and an offset for changing a position to start transmitting probe data. By using the transmission interval distances and the offsets, transmission start positions to transmit probe data are shifted on a running unit basis or on a vehicle basis. Therefore, while the vehicle stops, multiple data transmission at the same position does not occur. This can reduce the communication cost, and makes it possible to obtain information evenly on the travel route.
