Efficient traffic signal lamp control system and control method

Abstract

The invention discloses an efficient traffic signal lamp control system and control method, and the system comprises a traffic signal lamp which is used for outputting a traffic indication signal; a control device which is used for controlling the traffic indication state of each traffic signal lamp; a traffic flow detection device which is used for detecting and outputting the number value of vehicles to pass in each road or each lane in each direction; a data processing device which is used for receiving the number value, calculating the time ratio required by all vehicles on the current passable and impassable lanes to pass through the intersection based on the duration required by each vehicle to pass through the intersection, and dividing the passing duration for each road or each lane, and the control device is in signal connection with the data processing device. The traffic control signal is output based on the divided traffic duration, and the indication state of the traffic signal lamp is reasonably allocated by monitoring the number of the vehicles on the roads or lanes in all directions of the intersection and the required traffic time, so that the average waiting duration of the vehicles to pass on the roads or lanes in all directions is shortened, and the problem of road congestion is relieved.

Description

technical field [0001] The invention relates to the technical field of traffic lights, more specifically, it relates to an efficient traffic signal light control system and control method. Background technique [0002] A traffic signal light is an indicating device arranged at a road intersection for coordinating the passage of vehicles and pedestrians. Usually traffic lights are divided into three indication states of red, yellow and green. Vehicles and pedestrians pass through the intersection in an orderly manner following the rules of going on green lights and stopping on red lights. In the current traffic lights, the switching time between different indication states is usually fixed, such as the time for alternating traffic lights. [0003] Although the above setting method is simple, there are obvious deficiencies in practice. For example, the traffic flow in each direction of the intersection may be different at different time periods. For example, the traffic flow ...

Problems solved by technology

[0004] Aiming at the problem that the switching time between the indication states of traffic signal lights is fixed in practice and cannot be adjusted according to changes in road traffic flow, resulting in road congestion, which is not conducive to the travel of vehicles and pedestrians, the first purpose of the present invention is to propose an efficient traffic signal light control System, which can automatically adjust the switching interval between the indication states of traffic lights according to the traffic volume of roads in all directions at the intersection, so as to ensure the smoothness of the intersection
