Design of Illegal Occupation Inspection Facilities for Expressway Emergency

Expressway emergency lane is specially used for vehicles dealing with engineering rescue, medical rescue and other emergency services, any social vehicles are prohibited to enter or stay in the lane. However, the Expressway emergency lanes in China are occupied frequently, which makes it easy to cause delaying in emergency situations and results in serious consequences. Therefore, based on RFID technology, a testing facility for illegal occupation of emergency lane was designed. At the entrance of the toll station, the vehicle information is bound to the electronic tag ID and then distributed to the owner. In the detection area, a communication mechanism is established between the electronic tag, the microcomputer station and the signal lamp induction system by using the RFID technology. By receiving and launching signals, it's easy to detect illegal occupations of vehicles in the emergency lane and to remind the vehicle to leave quickly. At last, the feasibility analysis of the testing facilities shows that the facilities can quickly and accurately detect the vehicles that illegally occupy the emergency lane, and its detection accuracy and power supply capacity meet with the expected requirements. The research of this paper is of great significance to the management of China's expressway emergency lane.
