ON-VEHICLE DEVICE, TRAFFIC INFORMATION SYSTEM, ON-VEHICLE INFORMATION PROCESSING METHOD OF ON-VEHICLE DEVICE AND ON-VEHICLE INFORMATION PROCESSING PROGRAM OF ON-VEHICLE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide traffic information to respective vehicles so that the respective vehicles perform desired operation to prevent a traffic accident.SOLUTION: A host device 700 generates traffic information associated with all lanes. An information provision determination device 400 transmits the traffic information by using an electric wave widely propagating from a DSRC road side machine for information provision 300. A vehicle 101 receives the traffic information. Also, a light sensor 200 transmits lane information by using a light wave only narrowly propagating, and the vehicle 101 receives the lane information. Then, the vehicle 101 extracts traffic information on the traffic lane shown by the lane information and performs output control of a warning message of a car navigation system on the vehicle so as to prompt a driver to perform speed reduction or lane change. Moreover, an evaluation device 800 collects and evaluates traffic log data of the vehicle 101 through a DSRC road side machine for log collection 500, and controls information provision from the information provision determination device 400.
