Traffic signal data transmission method and traffic signal control system

Abstract

The invention discloses a traffic signal data transmission method and a traffic signal control system, and belongs to the technical field of traffic signal control. According to the technical scheme,the traffic signal control system comprises a traffic annunciator, a traffic flow monitoring module, a wireless communication unit, a traffic flow proportion presetting module and a base station center, and the output end of the traffic flow monitoring module is connected with the input end of the wireless communication unit. With the arrangement of a traffic flow analysis system, a traffic flow proportion presetting module and a signal lamp intelligent adjusting system, during system runtime, the transverse and longitudinal traffic flow proportions of a crossroad can be well calculated in real time, when the traffic flow proportions are approximately equal, the traffic signals can be switched according to a preset mode, and the system can adjust the switching time of the transverse traffic light and the longitudinal traffic light in real time when the difference between the transverse traffic flow proportion and the longitudinal traffic flow proportion is larger, thereby well deploying the switching of the traffic signal device in real time according to the traffic conditions, and improving the real-time performance and robustness of traffic deployment.

Description

technical field [0001] The invention belongs to the technical field of traffic signal control, and more specifically relates to a traffic signal data transmission method and a traffic signal control system. Background technique [0002] Where traffic separation cannot be achieved at road intersections, a traffic direction measure used to assign rights of way to traffic flow in time. The role of traffic signals is to scientifically allocate the right of way of vehicles and pedestrians on the road, so that they can pass smoothly in an orderly manner. Traffic lights (traffic lights) are light and color signals that alternate at a specified time, and are set at intersections or other special locations. A traffic control facility used to assign the right of way to vehicle drivers and pedestrians, and to control their behavior and turning. Use red, yellow, green three-color lights or supplemented by sound to instruct vehicles and pedestrians to stop, pay attention and move forwar...
