Abstract

The invention relates to artificial intelligence, and provides an intersection traffic signal control method and device and a storage medium; the method comprises the steps: determining a signal control object sub-region of a target intersection, and obtaining the basic data information of the signal control object sub-region; dividing a traffic flow change period of the signal control object subarea into at least two optimization time steps, and determining a queuing balance coefficient of the signal control object subarea in each optimization time step under the initial signal timing information; optimizing the initial signal timing information in each optimization time step of the signal control object sub-region according to the queuing balance coefficient to obtain optimal signal timing information in each optimization time step of the signal control object sub-region; and carrying out traffic signal control on the signal control object subarea based on the optimal signal timing information in each optimized step length time. According to the technical scheme provided by the invention, the problem of low traffic release efficiency of an existing traffic signal control method can be solved.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a traffic signal control method, system, device and storage medium at an intersection. Background technique [0002] Traffic signal control is a key part of the dynamic management and control of urban road intersections. It plays a vital role in organizing, commanding, and controlling the direction and flow of traffic at intersections, maintaining traffic order, and ensuring traffic safety. The essence of signal control is to separate the conflicting traffic flow in the intersection from time to time, so that it can obtain the right of way in different signal phases, so as to ensure traffic order, efficiency and safety. However, when the clearance time ratio of a phase (that is, a signal indication state) is larger, it is more conducive to the passage of traffic flow that obtains the right of way in this phase, and at the same time, it is less conducive to the passage of ...
