Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] A kind of single intersection signal timing method based on cooperative game theory cost apportionment method provided by the present invention comprises the following steps:

[0030] 1) Using the cost apportionment model in cooperative game theory to model and analyze single intersections, a single intersection signal timing model is obtained, including cost characteristic functions and cost apportionment functions.

[0031] The present invention regards the signal timing of the four phases of a single intersection as a cooperative game process in which four participants (each participant corresponds to a phase of a single intersection) participate, and adopts the cost sharing model in the cooperative game theory to Modeling and analysis of single intersections. Specifically, the following steps are included:

[0032] 1.1) Define the cost ch...

Abstract

The invention relates to a single-intersection signal timing method based on a cooperative game theory cost distribution method, and the method is characterized in that the method comprises the following steps: 1), carrying out the modeling analysis of a single intersection through employing a cost distribution model in the cooperative game theory, and obtaining a single-intersection signal timingmodel which comprises a cost feature function and a cost distribution function; 2), obtaining the calculation parameters of all phases of the single intersection through a vehicle-road cooperation system, wherein the calculation parameters comprise the queuing length of each phase in a former period, the vehicle entry rate and leaving rate of a current period, and a total signal lamp period of the intersection; 3), calculating and obtaining the green-light distributed time duration of each phase according to the obtained calculation parameters of each phase of the intersection and the signaltiming model. The method can be widely used in the field of signal timing of the single intersection.

Description

technical field [0001] The present invention relates to single intersection signal timing technology in traffic road network, in particular to a single intersection signal timing method based on cooperative game theory cost allocation method, the method uses game theory to analyze single intersection signal in traffic road network Carry out modeling to form a new single intersection signal timing scheme. Background technique [0002] In the current traffic road network, the signal timing of single intersections is the most basic and important research direction of traffic road network optimization. A suitable model for single intersections is established through various technologies, and the green light time of each phase Carrying out optimal control to achieve the optimal scheme of each traffic flow at the intersection has very important practical significance for improving urban road traffic congestion, improving road capacity, and reducing traffic accidents. [0003] Bas...
