TRAFFIC INFORMATION ARITHMETIC UNIT

摘要

PROBLEM TO BE SOLVED: To provide a traffic information arithmetic unit by which traffic information is acquired without placing a burden of input to a driver.

SOLUTION: The traffic information arithmetic unit includes: a traffic information collection device 1 which is provided in a vehicle C; and a traffic information storage device 4 which is provided in a traffic information center T. The traffic information collection device 1 calculates start delay time ratio to a reference link based on start delay time on a traveling route to transmit the start delay time ratio to the traffic information storage device 4. The traffic information storage device 4 corrects the start delay time ratio for every stored link based on the transmitted start delay time ratio to store the corrected start delay time ratio.
