TOLL COLLECTION SYSTEM, ON-VEHICLE EQUIPMENT, AND METHOD FOR COLLECTING TOLL

摘要

PROBLEM TO BE SOLVED: To charge a vehicle having traveled a toll road so as to evade a traffic jam section with a discount toll by using an ETC system. SOLUTION: The ETC system 2 detects a vehicle 12 trying to leave a toll road 30 from a tollgate existing this side of the traffic jam area and writes a jam evading flag in an IC card inserted into on-vehicle equipment 14 of the vehicle 12 through an exit lane control device 24. When the vehicle 12 entering the toll road 30 from a reentry-enabled tollgate exceeding the jam section is detected and the jam evading flag is read out from the IC card 10, the read flag is updates as a jam discount flag through an entrance lane control device 22. When the vehicle trying to leave the toll road 30 from a tollgate ahead of the reentry-enabled tollgate is detected and the jam discount flag is read out from the IC card 10, a discount charge is applied to the vehicle 12.
