Emergency vehicle intelligent traffic control system and method based on DSRC

Abstract

The invention provides an emergency vehicle intelligent traffic control system and method based on DSRC. The system comprises a signal lamp, a signal controller and a road side unit RSU connected in order, and an onboard unit OBU performing DSRC communication with the RSU; the OBU is used for collecting states of an emergency vehicle and a non-emergency vehicle in real time and transmitting the states to the RSU; the signal controller transmits a real-time state of the signal lamp to the RSU and receives a signal lamp phase control instruction and controls the signal lamp to make the corresponding action; the RSU is used for receiving signal lamp real-time phase information sent by the signal controller and the real-time state information of the vehicle sent by the OBU, and executing the corresponding signal lamp operation mode according to the above information and the control algorithm. Through the system provided by the invention, the signal lamp can be controlled to operate different modes according to the vehicle data, thereby enabling the emergency vehicle to quickly pass the intersection and guaranteeing the security of the non-emergency vehicle.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic, in particular to a DSRC-based emergency vehicle intelligent traffic control system and method. Background technique [0002] In urban traffic control, emergency vehicles such as ambulances, fire trucks, and police cars need to minimize their travel time and improve emergency response speed when performing designated tasks. If there is a red light in front of the emergency vehicle, it may cause the emergency vehicle to be unable to pass through the intersection quickly, thus affecting the execution of the task. Traffic regulations stipulate that when performing tasks, they can run a red light on the premise of ensuring driving safety, but there will be certain risks in running a red light. An emergency vehicle running a red light may cause vehicles in the orthogonal direction to brake not in time, resulting in accidents. Therefore, it is of great significance to study the safe and eff...
