Embodiment Construction

[0044] The premise of line coordinated control is that the running cycle of each intersection within the coordinated control range is the same. Therefore, the green signal ratio optimization method proposed in this method uses the green signal ratio optimization principle under the induction control mode, and performs green signal ratio optimization in a certain fixed period. Signal ratio optimization.

[0045] In the online coordinated control mode, the coordinated phase refers to the operation time of this phase in a certain intersection to participate in the calculation of the phase difference in the line coordinated control. The non-coordinated phase refers to all other phases in the intersection except the coordinated phase, and the coordinated phase is run at the reference intersection. After the phase, coordinate intersection i at a specified time t i To run the coordinated phase of intersection i, the specified time t i The determination method is as follows:

Abstract

The invention discloses a traffic signal coordination control method for urban road, belonging to the intelligent traffic signal system control technology field. The intersection signal coordination control optimization method based on inductive control model comprises the steps as follows: combining with the flexibility character of the inductive control and the line coordination control principle, providing the intersection signal coordination control optimization method based on inductive control model, giving the corresponding switching method and optimization method. The method can respond the vehicle arriving information of each phase of each crossing, determine the phase switching method according to the coordination phase working time, non-coordination phase working time and phase difference; the method is used for coordination control for the urban road, compared with the conventional green wave band control, the green time is saved, the vehicle queuing length is reduced and the road capacity is improved.

Description

technical field [0001] The invention provides a traffic signal coordination control method for urban roads, which belongs to the technical field of intelligent traffic signal system control. Background technique [0002] Urban traffic signal induction control is a very important traffic signal control mode. In the unsaturated state of traffic flow, for a single intersection, when induction control is adopted, when there is a vehicle passing demand in a certain direction, it is a green light, and there is no vehicle passing demand. That is to say, it becomes a red light, as if the signal light has "long eyes". Therefore, induction control is widely researched and applied in small and medium-sized cities at home and abroad at present. However, induction control also has considerable disadvantages. It is only suitable for signal control at a single intersection with a small traffic flow, and lacks interaction between upstream and downstream intersections, making it impossible t...
