Motor vehicle stream-oriented intersection traffic pre-signal control method

Abstract

The invention discloses a motor vehicle stream-oriented intersection traffic pre-signal control method and relates to an intersection traffic signal control method. The invention aims to solve the problems that the intersection traffic capacity is reduced and motor vehicles are jammed due to the fact that the distance between a pre-signal stop line and a main stop line is determined according to subjective experiences and the timing plane of a pre-signal and a main signal cannot be regulated according to dynamic changes of traffic flow by adopting a traditional intersection traffic pre-signal control method. The motor vehicle stream-oriented intersection traffic pre-signal control method comprises the following steps of: performing intersection entrance lane organization and signal control facility layout; performing static traffic data acquisition according to the signal control facility layout finished in the step I; enabling an intersection to adopt a four-phase signal control method, and enabling the pre-signal and the main signal to be same in phase and phase sequence setting; and performing coordination control of the main signal and the pre-signal by utilizing a signal control facility in the step I and static traffic data in the step II according to the four-phase signal control method in the step III. The motor vehicle stream-oriented intersection traffic pre-signal control method disclosed by the invention can be widely applied to intersections to perform traffic signal control.

Description

Technical field [0001] The invention relates to a traffic signal control method at a cross intersection. Background technique [0002] At present, the traffic congestion in major cities in my country is gradually deteriorating, and the number of oversaturated intersections is increasing, which seriously hinders the social and economic development. The main reason for the oversaturation phenomenon at intersections is that the arriving traffic flow is greater than the capacity of the intersection, so increasing the capacity of the intersection has become an important means to solve traffic congestion. The traffic capacity of an intersection is closely related to the lane organization and signal timing plan. The pre-signal control method controls the flow of motor vehicles by adding a stop line and a set of signal lights after the stop line at each entrance direction of the intersection. The organization and signal timing plan improve the traffic capacity of intersections, which ca...

Problems solved by technology

[0004] In order to solve the problem that the existing intersection traffic pre-signal control method determines the distance between the pre-signal stop line and the main stop line based on subjective experience, and the timing scheme of the pre-signal and main signal cannot be adjusted according to the dynamic change of traffic flow, As a result, the traffic capacity of the intersection is reduced and the problem of motor vehicle congestion is caused. A traffic pre-signal control method at the intersection oriented to motor vehicle flow is provided.
