Abstract

The invention discloses a coordination control method and system for a main-branch path mixing area. The method comprises the steps that the main-branch path mixing area is divided into a plurality of sub-areas; for each sub-area, moving amount between actual intersections and set ideal intersections in the sub-area is obtained based on each ideal intersection separation distance in a plurality of set ideal intersection separation distances, and the best period of the sub-area and the best phase difference of all the intersections in the sub-area are determined based on the moving amount; for each intersection in each sub-area, the intersection predicted saturability of each scheme of a plurality of preset split schemes used in the next period is calculated, and the split scheme corresponding to intersection predicted saturability with the minimum value is determined to be the best split scheme of the intersection. The coordination control method and system for the main-branch path mixing area reduce algorithmic complexity, reduce systemic input quantity, and can conduct coordination control on the area dynamically in real time.

Description

technical field [0001] The invention relates to the field of traffic management and control, in particular to a coordinated control method and system for mixed areas of main and branch roads. Background technique [0002] With the rapid development of the economy, the number of vehicles in our country is extremely inflated. Under the condition that the road area does not expand accordingly, the serious traffic jam has become one of the biggest problems in all urban management, and has increasingly become an important factor hindering urban development. Designing a reasonable regional coordinated control scheme is the most important way and approach to solve road traffic congestion and optimize traffic distribution. [0003] At present, the more successful and widely used regional control systems in foreign countries include the scheme-selective SCATS system, the fixed off-line control system TRANSYT, and the scheme-generating SCOOT system. However, the SCACT system does not...
