Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, the structural representation of the traffic crossing in the present invention is provided, the traffic crossing shown is provided with the signal light 3 that controls the passage of vehicles, the motor vehicle travels on the carriageway 2, and the front end of each crossing is all provided with a camera 1, The camera 1 is used to capture the vehicles passing through the intersection. The camera 1 is installed on the support 4. According to the requirements of traffic regulations, it is necessary to collect the frontal photos of the driver. Therefore, the number of cameras 1 is at least two, one facing forward and one facing Rear. The shown bracket 4 is also provided with a speedometer 7 and a supplementary light 8, so as to realize the speed measurement of the past measurement and the illumination when the light is i...

Abstract

The invention relates to a traffic signal control method for convenient emergency vehicle passing. The method comprises: (a), a license plate number is collected and issued; (b), whether a vehicle passes through an intersection is determined; (c), a lane where the vehicle is located is determined; (d), a current signal lamp state is determined; and (e), changing for a go-ahead signal is carried out as soon as possible. According to the invention, the license plate number of the emergency vehicle needing the priority of going ahead is issued to a signal lamp controller of a traffic intersection; when the emergency vehicle is identified to pass through the intersection by the image shot by the camera, the vehicle is allowed to pass through the intersection. Therefore, the traditional releasing way that all signal lamps are changed into green lights on the route needed by the emergency vehicle is changed; and while the emergency vehicle is released in priority, the influence on the existing traffic order is minimized. The beneficial effects are obvious; and the method is suitable for popularization and promotion.

Description

technical field [0001] The invention relates to a traffic signal control method for emergency vehicles to pass, more specifically, to a traffic signal control method for emergency vehicles to pass through as soon as possible when a vehicle is detected passing through an intersection. 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 bus lane or during rush hour, 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 re...
