When a vehicle has reached an entry gate, toll information, such as the type of the vehicle, time and date, etc. are detected and printed on a passage coupon, which is automatically issued at a certain position corresponding to the type of vehicle to be taken by a driver. A highway toll is collected at an exit gate by reading the information on the passage coupon and calculating toll for the vehicle. The information printed on the passage coupon and the information relative to toll calculation are transmitted together with the information concerning the current state of running on the highway to a central control office. A passage coupon issuance unit disposed at the entry gate contains more passage coupons for regular sized vehicles than for other type of vehicles and issues them through passage coupon issuance ports. When a vehicle has entered the highway without a passage coupon being picked up by a driver on the vehicle, the passage coupon which was not picked up is retracted into the passage coupon issuance port. |
