The non-stop toll collection system (also known as the Electronic Toll Collection System, ETC system for short) uses Automatic Vehicle Identification (AVI) technology to complete the wireless data communication between the vehicle and the toll station for automatic vehicle identification and related toll collection. For data exchange, toll data is processed through a computer network to realize a fully electronic toll collection system for automatic non-stop toll collection.
Through the special microwave short-range communication between the on-board electronic tag installed on the vehicle windshield and the microwave antenna on the ETC lane of the toll station, the computer networking technology is used for background settlement processing with the bank, so that the vehicle does not need to pass the road and bridge toll station. The purpose of paying road and bridge tolls when parking. ETC is an electronic automatic toll collection system for highways, bridges and tunnels that is being developed and promoted internationally. This technology has a long history of development abroad, and the electronic toll collection systems in many countries and regions such as the United States and Europe have been partially networked and gradually formed economies of scale. Our country’s highway network toll collection, which uses IC cards and magnetic cards as media and adopts manual toll collection methods, is undoubtedly also affected by this trend.
The non-stop toll collection technology is particularly suitable for use in highways or bridges and tunnels with heavy traffic. The non-stop toll collection system under the traditional lane isolation measures is usually called the single-lane non-stop toll collection system, and the non-stop toll collection system under the free traffic flow under the condition of no lane isolation is usually called the free flow non-stop toll collection system. The implementation of non-stop toll collection allows vehicles to pass through at high speeds (tens of kilometers or even more than 100 kilometers), which can greatly increase the capacity of highways; the trend toward electronic toll collection on highways can reduce the cost of toll management and improve the operating efficiency of vehicles; At the same time, the noise level and exhaust emissions of the toll gate can be greatly reduced. As traffic capacity has been greatly improved, the scale of toll stations can be reduced, and infrastructure and management costs can be saved. In addition, the non-stop toll collection system is not only an advanced toll technology for cities, it is also a practical and effective traffic management method that regulates traffic flow through economic levers. For bridges and tunnels with heavy traffic, the non-stop toll collection system can avoid the many weaknesses of the monthly ticket system and manual toll collection, and effectively improve the fund recovery capacity of these municipal facilities.
