PROBLEM TO BE SOLVED: To provide a transmission system and an equipment between vehicles for reducing a number of packets in a multi-hop broadcast communication between vehicles. SOLUTION: The present invention: determines a position data including positions, travel speeds and the run directions of receiving vehicles (1, 2, 3, 4); receives the position data including positions, travel speeds and the run directions of transmitting vehicles (1, 2, 3, 4); and computes relative positions between the receiving vehicles (1, 2, 3, 4) and the transmitting vehicles (1, 2, 3, 4). It computes a vehicle density from a computed relative position vehicle, and a time duration for transmitting periodically from the receiving vehicle the position data of the receiving vehicles (1, 2, 3, 4) is established according to this vehicle density.
