A traffic signal control game method and system for regional overflow prevention

Abstract

The invention discloses a regional anti-overflow traffic signal control game method and system. The method comprises the steps: acquirig a road segment attribute parameter and a node attribute parameter in a control region, determining a detection region on the control region, and enabling the road segment attribute parameter to comprise an associated traffic flow; acquiring vehicle data in two adjacent detection regions, comparing the vehicle data with a preset road segment overflow threshold value, and acquiring a road segment overflow state level soi at the current moment; according to theroad segment overflow state level soi, constructing an equilibrium target function based on the associated traffic flow, and obtaining a mixed integer linear programming model of a regional anti-overflow signal control strategy game; carrying out calculation according to the mixed integer linear programming model to obtain a passage right distribution strategy of each turning direction in an intersection, realizing a passage right distribution strategy through single-point and coordination signal control, and achieving anti-overflow control of regional traffic flow; self-adaptive control overoverflow prevention of regional signals is achieved, and the road network operation pressure is relieved.

Description

technical field [0001] The invention relates to the technical field of urban intelligent traffic control, in particular to a traffic signal control game method and system for regional overflow prevention. Background technique [0002] In recent years, the increase in the number of motor vehicles in cities has caused the existing urban road network to face huge operating pressure, especially in some road sections during peak hours due to improper signal control, resulting in too many vehicles stranded inside, resulting in the risk of overflow. If there is an overflow of vehicles inside the intersection, it will cause the loss of green lights and deadlocks at the intersection. If it is not handled in time, it will trigger a chain reaction in the adjacent area, leading to a domino-style collapse of the regional traffic system. At present, the most widely used regional traffic signal control systems in the world are the British TRANSYT system, the SCOOT system and the Australian...

Problems solved by technology

[0003] In solving the regional traffic signal control problem of the above systems and application methods, since the coordinated linkage control and the overflow control belong to two isolated systems, when the coordinated linkage control has overflow problems or risks, switch to the overflow control mode or perform simple overflow control Measures, there are overflow real-time control intersection isolation or experience control problems, it is difficult to obtain a balanced control plan from the overall level
