Abstract

The invention discloses a control method of single intersection signal adaptation. A single intersection signal adaptation control model based on smallest delay time is firstly established, and then improved harmony searching algorithm solving is put forward. The control method comprises specific steps of (1) establishing single intersection signal adaptation control model; (2) initializing algorithm parameters; (3) generating a new timing scheme; (4) using the improved harmony searching algorithm to dynamically update the harmony memory library probability, the fine tuning disturbance rate and adjustment step length; (5) updating a harmony memory library; (7) judging whether the biggest iteration times is met; and (7) obtaining the optimal harmony to serve as a green light timing scheme corresponding to the intersection. According to the invention, a single intersection adaptive timing scheme can be effectively solved; and the method is suitable for an optimization problem of the single intersection signal adaptation.

Description

technical field

[0001] The invention relates to the field of traffic signal adaptive control, in particular to a signal adaptive control method at a single intersection. Background technique

[0002] Single intersection signal adaptive control is the most basic control form in traffic adaptive control. In order to solve complex regional traffic adaptive control problems, it is necessary to start with single intersection signal adaptive control, in order to solve complex regional adaptive control. Control problems provide the basis for research. The core of adaptive signal control at single intersections lies in the dynamic generation of traffic signal timing schemes.

[0003] The existing technology is mainly to determine a fixed timing scheme for a single intersection through experience, and it is difficult to dynamically change the traffic control scheme according to different traffic conditions. Contents of the invention

[0004] In order to solve the shortcomings of ...
