1. Introduction to the system
The road and bridge electronic toll management system is specially designed to solve the problem of modern transportation, especially the highway toll. By adopting RFID technology, the road and bridge pass without parking, no cash, no manual intervention, automatic toll collection and accurate and reliable, thus reducing the car’s cost. Mechanical wear, fuel consumption and exhaust gas emissions speed up the passing speed of cars, improve the efficiency of roads and bridges, and minimize the possibility of missed collections.
Shantou’s road and bridge electronic toll collection system mainly uses radio frequency electronic tag identification technology, which firstly meets the inspection and management of annual tolls, and reserves information access ports for various management functions such as vehicle maintenance fee collection, annual inspection, and transportation management. And effectively prevent the use of fake cards and sets of cards to evade payment of annual pass tolls, and improve road capacity. The project was launched in November 2009 and passed the preliminary acceptance. There are 150,000 vehicles with electronic tags installed in Shantou City, and the tag recognition accuracy rate is 99.97%. This not only greatly improves the road capacity, but also greatly reduces the average passage time per vehicle in the lane. Vehicle exhaust emissions can realize automatic vehicle identification and efficient management, which is of great significance to further strengthen the management of annual tolls for road and bridge tolls, improve the traffic environment, and save energy and reduce emissions.
2. System composition
The system includes automobile electronic identification reading and writing system, lane control equipment, monitoring computer, and toll network system.
Three, work flow
When the vehicle passes the road and bridge lane and enters the communication area of the lane antenna, the electronic tag installed in the vehicle immediately sends vehicle information, driving record information and other information to the lane antenna. After the lane antenna receives the information, the information is transmitted to the transaction controller through the transaction controller. The lane control machine, after the information is processed by the lane control machine, the current driving record and other information are transmitted to the lane antenna in the reverse direction, and finally the electronic tag of the vehicle is written.
In this way, each toll station can calculate the toll receivable by obtaining the driving record of the vehicle, and then deduct the account from the bank account opened by the owner of the vehicle through the toll network to realize automatic charging.
Four, system advantages
Long-distance reading, high-speed acquisition of carsElectronic tagInformation, the accuracy rate is not less than 99.7%;
Innovative technology, comprehensively and effectively solve the interference problem of adjacent vehicles;
24 hours uninterrupted work without supervision;
The vehicle label has a unique anti-dismantling function, and can also be used in conjunction with an electronic license plate to ensure “one car, one card”;
Improved toll processing capacity and lane traffic rate, avoiding traffic congestion;
Automatic management around the clock, adapt to all kinds of bad weather.
5. System implementation benefits
First of all, the application of the road and bridge electronic toll management system can allow vehicles to pass through at high speed (the speed is kept at tens of kilometers per hour), which can greatly improve the traffic capacity of the road; at the same time, the electronic toll collection of roads can reduce the cost of toll management, which is beneficial to Improve the operating efficiency of vehicles, and can greatly reduce the noise level and exhaust emissions of toll gates. As the traffic capacity has been greatly improved, the scale of toll stations can be reduced, and infrastructure and management costs can be saved.
Secondly, the implementation of this project has established Shantou’sCar RFIDThe basic management platform: (1) All units and public parking lots can easily implement parking fee management; (2) The transportation department can implement blue-plate car inspections, vehicle anti-theft looting, traffic flow monitoring, etc.
In addition, the electronic 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 sections such as 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.
