PROBLEM TO BE SOLVED: To optimally set road information necessary to safety driving and automatic operation in accordance with an individual vehicle by transmitting the road information suitable for the vehicle. SOLUTION: The road information is acquired from the center communicating part 14 of a roadside device 1, a road surface sensor 15, a traffic flow monitoring sensor 16 and a fixed value storage memory 17. When a vehicle sensor 11 detects that a vehicle approaches, a controlling part 13 transmits the road information corresponding to the type of the approaching vehicle through a DSRC communicating part 12. A controlling part 22 outputs an instruction to a driver by visible display on the basis of the road information received through the DSRC communicating part 21 of an on-vehicle device 2 and outputs voice and an alarm tone from a sound output device to output an instruction and an alarm. It also instructs the driver to release the accelerator, to perform shift down of transmission and to apply the brake. |
