Problems solved by technology

[0003] In the related technology, in the control of signal lights, a variety of signal control schemes are pre-stored in the signal machine at the intersection. Each signal control scheme corresponds to a time period, and the signal lights are controlled according to the matching signal control scheme within the corresponding time period. Taking into account the actual situation of the current traffic flow, resulting in unreasonable control of the traffic flow, causing traffic congestion, etc.

Abstract

The invention discloses a traffic scheme control method and device, and relates to the technical field of intelligent traffic, and the method comprises the steps: obtaining the green light waste time of each lane in each flow direction of a traffic intersection in the green light passing time; obtaining the class saturation of each lane, and obtaining the class saturation of each flow direction according to the class saturation of each lane; obtaining the class saturation of the current control scheme by combining the class saturation of each stage flow direction in the current control scheme; calculating the class saturation of each candidate control scheme; determining a target control scheme corresponding to the minimum class saturation according to the class saturation of each candidate control scheme, comparing the class saturation of the current control scheme with the minimum class saturation, and if the class saturation of the current control scheme is greater than the minimum class saturation, controlling the signal control machine to control the next passing period of the traffic intersection according to the target control scheme. Therefore, the reasonability of the adopted signal control scheme is ensured, and the traffic smoothness is improved.

Description

technical field [0001] The present application relates to the field of intelligent transportation technology in data processing technology, and in particular designs a traffic scheme control method and device. Background technique [0002] With the increase of vehicles owned by users, the smooth flow of traffic has become the primary problem to be solved. Usually, the traffic light signal control of the signal machine is used to control the passage of vehicles to adjust the pressure of traffic. [0003] In related technologies, in the control of signal lights, a variety of signal control schemes are pre-stored in the intersection signal machine, each signal control scheme corresponds to a time period, and the signal lights are controlled according to the matching signal control scheme within the corresponding time period. Taking into account the actual situation of the current traffic flow, resulting in unreasonable control of the traffic flow, causing traffic congestion and...
