Abstract
A map data storage unit holds map data in which a road ID is allocated, as identification information, to every preset section of at least part of roads. A traffic jam determination unit determines whether the section corresponding to every road ID is congested. A transmission unit performs broadcast transmission of vehicle data including a road ID and the traveling speed of a vehicle from the vehicle traveling in each section of a road. At the time, the transmission unit forms a frame in which the received vehicle data of other vehicle and the vehicle data of a driver'"'"'s vehicle are combined. An information compressing unit compresses an amount of data by deleting the traveling speed from the frame with respect to a section that has been determined not to be congested by the traffic jam determination unit.
