Wireless traffic signal system and method thereof cooperated with vehicle tracks at intersections

Abstract

The invention relates to the technical field of traffic control, in particular to a wireless traffic signal system and a method thereof cooperated with vehicle tracks at intersections. The invention adopts a special short-range communication mechanism. The system comprises intersection transmitting equipment, vehicle receiving equipment, a singlechip, voice output equipment, GPS (Global Position System) equipment and a vehicle display. The singlechip carries out data fusion processing on real-time traffic information and the longitude and the latitude of vehicles to obtain information of traffic signal lamps on the vehicle tracks and outputs the information to the vehicle display. The method comprises the step that the singlechip carries out data fusion on information of an electronic map, a real-time traffic lamp signal, vehicle track positioning and traveling direction and displays the traffic signal on the electronic map when the vehicles enter the communication range of a special short-range communication technology. The invention can ensure that the traffic signal is transmitted to the vehicles through the system under the condition that a driver cannot clearly see the front signal lamps and thereby the driver can clearly know about the current contents displayed by the traffic signal lamps by using a display or voice prompt system.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a wireless traffic signal system and method for vehicle-road coordination at intersections. Background technique [0002] In order to strengthen road traffic management, reduce traffic accidents, and improve road use efficiency, traffic signal lights are usually set up at cross and T-shaped intersections. Traffic signal lights are divided into motor vehicle signal lights, lane signal lights, direction indicator lights, etc. Three colors of lights, yellow and green, are used to indicate whether all directions of the intersection can pass. Lane signal lights use signal lights composed of fork patterns and arrow patterns, and direction indicator lights indicate vehicles to pass in the indicated direction. [0003] When the driver passes the intersection, he should use the visual method to see clearly the status of the traffic lights ahead. When the sun is strong or in sever...

Problems solved by technology

[0004] The purpose of the present invention is to provide a wireless traffic signal system and method for vehicle-road coordination at an intersection, so as to overcome the shortcomings of the existing traffic signal system, so that when the vehicle is running, no matter what vehicle is blocking the front or the weather is abnormally bad Be able to get the signal of the traffic light ahead
