(54) Traffic information communication system, on-board communication device, and mobile terminal


(57) There is provided an on-board communication terminal that may notify a driver at appropriate timing of vehicle drive information transmitted from a vehicle that is dangerous to its own vehicle even though a number of vehicles are around its own vehicle. A traffic information communication system according to the present invention includes an on-board communication device equipped in a vehicle. The on-board communication device includes a navigation unit that obtains vehicle drive information of the vehicle and a communication device unit that broadcasts the vehicle drive information obtained by the navigation unit at a predetermined frequency and outputs drive information received from the on-board communication device of another vehicle or pedestrian information received from a mobile terminal to the navigation unit. The navigation unit adds under-detection-of-a-to-be-watched-vehicle information that detects a vehicle ID of a to-be-watched vehicle as a to-be-watched vehicle to the vehicle drive information of its own vehicle.
