1. Business requirements
With the improvement of people’s living standards, the number of motor vehicles in the city has gradually increased, and congestion has become more and more serious, especially in road and bridge toll sections, where “intestinal obstruction” often occurs, which directly increases residents’ travel time and costs, and reduces work. Efficiency and urban vitality are greatly reduced, and the quality of life of residents also declines. Traffic congestion will not only lead to the decline of various economic and social functions, but also cause the continuous deterioration of the urban living environment, becoming a “urban ailment” that hinders development.
The establishment of an urban road and bridge non-stop toll collection system can realize automatic identification, automatic deduction, and automatic release of vehicles, which greatly reduces the workload of personnel and improves work efficiency.At the same time, the establishment of an urban road and bridge non-stop toll system also has the following significance: through the use of advancedRFIDElectronic tag technology strengthens the supervision and management of toll vehicles, effectively prevents and combats evasion of vehicle tolls, alleviates traffic congestion, gives full play to the capacity of roads and bridges, improves the use efficiency of transportation resources, and fair charging burden, to meet the needs of society .
Second, the system architecture
The architecture of the urban road and bridge non-stop toll collection system is shown in Figure 3A, which is mainly composed of an electronic toll collection on-board unit (OBU), an electronic toll roadside unit (RSU), and system application software.
By pre-issued and installed on the vehicle, Dingshi “ETC-O2 electronic toll on-board unit”, when passing through the automatic toll lane of the toll station, the Dingshi “ETC-R2 electronic toll roadside unit” automatically obtains vehicle information, and Compare with the vehicle information database in the system, automatically deduct fees and lift the rod to release eligible vehicles, and intercept, alarm, and register unqualified vehicles. The system application software performs statistics, analysis, and summary of all data, and provides automated levy inspection management methods for management units.
Three, application process
Application process of urban road and bridge toll collection system
Fourth, the software module
The urban road and bridge non-stop toll collection system includes electronic label issuance system, parameter management system, business report management system, real-time lane monitoring system, suspicious vehicle inspection system, background database system, and external information orientation platform. The expansion of the system includes providing information access interfaces for other functional departments and authorized users to realize resource sharing. By adopting a system architecture based on the B/S model and using a “zero” software deployment method, all the management functions of the general control center are realized in the desktop browser of the remote control center.
Five, system characteristics
1. Minimize the traffic delay caused by the charging process and improve the charging efficiency.
2. Highly automated operation to ensure accurate charging and prevent arbitrary charging and private fraud.
3. Reliable crossing control to ensure vehicle safety.
4. Easy to operate, maintain and expand.
