信號交叉口不對稱交通流的優(yōu)化控制方法研究
[Abstract]:In recent years, urban road network traffic problems occur frequently, the research on traffic management and control of intersections has been paid more and more attention. When the intersection signal control scheme does not coordinate with the traffic flow, the traffic load will be uneven and the efficiency of space-time resource utilization will be low, which will affect the overall traffic benefit of the intersection. In this paper, a real-time optimal adaptive signal control method is proposed based on the asymmetry of traffic flow arrival in signalized intersection and the spatial design of intersection. Firstly, several typical urban road signalized intersections are selected, and their spatio-temporal resource allocation methods are investigated, and the adaptability of the signal control scheme of the intersection is analyzed and the problem diagnosis is made. Based on the data obtained from field investigation, with the help of VISSIM simulation and taking vehicle delay as the evaluation index, the influence of the change of traffic flow asymmetry on the effect of intersection signal control scheme is analyzed. The optimal threshold of asymmetric traffic flow in symmetric release scheme is defined. Then, the operational characteristics of asymmetrical traffic flow at signalized intersection are analyzed in depth, and the existing traffic organization schemes considering asymmetrical traffic flow are summarized in detail, and the unresolved problems in this respect are pointed out. Then, considering the asymmetrical traffic flow operation characteristics of signalized intersection, in order to maximize the utilization of the spatial resources of the intersection, this paper sets the left-turn-pending area and the direct-pending area of each inlet road at the same time, and on the basis of this space design, An adaptive signal control method based on rule and optimization model is proposed. Finally, from the angle of space-time resource utilization and operation efficiency of intersection, we select the utilization ratio of space-time resource, intersection saturation, vehicle delay, average queue length and parking rate as the evaluation index. The analytic hierarchy process (AHP) is used to construct the evaluation system of the comprehensive operation benefit of intersections. Taking the intersection of Hongqi Street-Huaihe Road in Harbin as an example, with the help of VISSIM simulation, this paper compares and analyzes the methods of space-time resource arrangement at the intersection and the advantages and disadvantages of the optimization design scheme proposed in this paper, and finds that the comprehensive operation benefit of the optimized intersection is improved after optimization. All the indexes have been improved to some extent, thus validating the correctness and effectiveness of the method.
