Phase timing optimization method for regional control based on lane saturation

Abstract

The invention provides an area control phase timing optimization method based on lane saturation, which identifies congested road sections in the area, analyzes the associated road sections, namely adjacent signal-controlled intersections and the non-congested traffic direction of the signal-controlled intersection, that is, the control direction, and adjusts the phase timing To achieve the optimization of the regional signal scheme. According to the saturation of the road, the method of the invention identifies the control direction that can be coordinated and optimized to reduce the length of the green light, and then adjusts the green light duration of the overlapping phase by adding an overlapping phase / late opening and early closing phase, effectively adjusting the phase sequence And the method of optimizing the duration of green lights realizes the optimization of the traffic signal scheme at the intersection, thereby realizing the optimization of the traffic signal area, which greatly improves the efficiency of area optimization, and avoids the traditional optimization method that can only adjust the duration of green lights in each phase, and the inconsistent demand for green lights in the same stage. regional congestion problem.

Description

Technical field[0001]The present invention relates to a method of controlling phase transfer optimization method based on a regional control phase of a driveway saturation.Background technique[0002]With the continuous development of the economy, the urban scale continues to expand, the year-on-year growth of automobile insurance, the problem of urban road traffic congestion is becoming more serious, and intelligent traffic signal control is an important means of easeing urban traffic congestion and improving urban transportation system operation efficiency. one. At present, in the study of traffic control optimization management, in single point, trunk lines and areas, where regional traffic signal controls all traffic signals, with green time difference, green light time, signal cycle to optimize each intersection signal scheme, Realize the effect of regional optimization.[0003]Patent CN201410035986.6 proposes "A Active Urban Road Region Method Coordination Optimization Method", by...

Problems solved by technology

[0004] The purpose of the present invention is to provide a lane saturation-based regional control phase timing optimization method to solve the current stage traffic signal regional coordination optimization adjustment method existing in the prior art is relatively complicated, and due to the adjustment of the green light duration of other traffic phases , will lead to congestion in the rest of the road sections in the area, and at the same time, it can only solve the problem of optimizing the green light duration of the phase phase phase of the signal control scheme at each intersection
