Abstract

The invention discloses a single-intersection signal timing method based on sequential gaming, and the method is characterized in that the method comprises the following steps: 1), building an infinite sequential gaming model for representing the timing moment of each phase signal of a single intersection, and determining a revenue function and a discount factor of the model; 2), obtaining a revenue function calculation parameter of each phase of the single intersection in a current period and a queuing length of each phase in a former period through a vehicle-road cooperation system, whereinthe revenue function calculation parameter and the queuing length are used for the gaming calculation of a sequential model; 3), taking each phase of the single intersection as a participant of the infinite sequential gaming model for sequential gaming, and calculating and obtaining the passing time distributed to each phase of the single intersection in a current period according to an obtained sequential gaming equilibrium solution and the duration of a period of the single intersection. The method can be widely used in the field of single intersection signal timing.

Description

technical field

[0001] The invention relates to a signal timing technology for a single intersection in a traffic road network, in particular to a signal timing method for a single intersection based on sequential games. Background technique

[0002] In the urban traffic system, signal timing at intersections is the basis for solving traffic jams. Through reasonable signal timing, coordination and optimization, the fluency and safety of urban arterial traffic can be effectively improved, and urban traffic pressure can be greatly relieved. However, in practice, many urban intersections only use the simplest timing method, and there is still a lot of room for improvement in efficiency.

[0003] Based on this, it is of great economic and theoretical value to study signal timing technology at single intersections. Judging from the current popular methods, they can be roughly divided into the following categories:

[0004] 1. Webster timing method.

[0005] Webster's timing m...
