A run efficiency measuring system measures both investment into a vehicle for run and actual run performance by the vehicle. The investment means cost of energy, toll, and budgeted time, while the actual run performance means travel distance and saved time. Run efficiency is calculated on the measurements separately by difference in driver, between toll run and free run, and in unit price of energy. The measurement is summarized every time when one of the differences occurs, or day changes, or predetermined travel distance has been run. Vehicle is in wireless communication with IC card type certificate integrated with credit card which is inserted into card slot of the vehicle to identify driver for the individual run efficiency calculation, authentication as qualified driver, and ETC payment. Run efficiency data gotten in a vehicle can be taken over to next different vehicle for accumulation by way of memory of the certificate. |
