Traffic priority control method for emergency vehicle

Abstract

The invention discloses a traffic priority control method for an emergency vehicle. A vehicle control mechanism, a vehicle identification mechanism, a jam computer, a radar transmitter and a traffic light manager are adopted, wherein the vehicle control mechanism is used for collecting license numbers of all vehicles on an urban road and corresponding vehicle position information; the vehicle identification mechanism comprises a first radar detector arranged in a detection area, a camera, first sending equipment and a first controller; the jam computer is used for searching a license number inthe detection area and corresponding vehicle position information to judge a jam situation; the radar transmitter is arranged in the emergency vehicle; the traffic light manager comprises a second radar detector, second sending equipment, a second controller, an automatic control mechanism and an emergency mechanism. According to the traffic priority control method for the emergency vehicle, an automatic-manual combined control system is arranged to make at least one emergency vehicle bedetained in the detection area have a traffic priority, so as to timely achieve functions of the emergencyvehicle, thereby alleviating the jam situation of the whole traffic.

Description

technical field [0001] The invention relates to the field of transportation, in particular to a method for controlling the priority passage of emergency vehicles. Background technique [0002] With the increasing number of motor vehicles in our country, traffic congestion has become a traffic problem faced by more and more cities. When a crisis situation occurs, emergency vehicles such as ambulances, fire engines, and engineering rescue vehicles need to pass in a timely and smooth manner to ensure the safety of people's lives and property to the greatest extent. However, when there is no special lane for emergency vehicles or during rush hours, it will seriously affect the passage of emergency vehicles; although emergency vehicles have the right not to be restricted by traffic lights, they still cannot quickly pass through intersections in case of traffic jams. Carry out patient rescue, fire extinguishing or engineering emergency operations in a timely manner. Contents of...
