Abstract

The present invention is suitable for the intelligent traffic technology field, and provides a system and method for priority pass of an emergency vehicle based on the V2X technology. The system comprises a location unit arranged on an emergency vehicle, a road side unit arranged at the side of a crossing and a traffic light control unit. The location unit is configured to obtain the position of the emergency vehicle on time and send the position of the emergency vehicle to the road side unit when the emergency vehicle accesses a vehicle and road wireless communication range; the road side unit is configured to determine the lane where the emergency vehicle is located and the position of the lane, generate the control instruction of the traffic light and transmit the control instruction to the traffic light unit according to the current position of the emergency vehicle; and the traffic light control unit is configured to control the state of the traffic light of the lane where the emergency vehicle is located based on the control instruction. The scheme of the priority pass of the emergency vehicle provided by the embodiment of the invention is designed based on the current position of the emergency vehicle, and the design idea is simple so as to have high practicality.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a V2X technology-based emergency vehicle priority passage system and method. Background technique [0002] Ambulances, fire trucks and other emergency vehicles are important tools for dealing with emergencies. During the implementation of emergency rescue, they are often restricted by traffic flow and signal lights at intersections, resulting in delays in rescue and even safety accidents. Therefore, it is of great significance to study the priority traffic control of emergency vehicles at intersections and improve their traffic efficiency and safety. [0003] At present, there has been an intersection emergency vehicle priority system constructed using wireless communication technology, which can effectively improve the efficiency of emergency vehicles, but the existing emergency vehicle priority system design is more complicated, such as the priori...
