Chain type feedback multi-intersection signal lamp decision-making system and method based on in-out road condition information

Abstract

The invention discloses a chain type feedback multi-intersection signal lamp decision-making system and method based on in-out road condition information. The system comprises intersection signal lamp decision-making devices applied to a plurality of intersections of a to-be-decided area and based on in-out road condition information, wherein the plurality of intersection signal lamp decision-making devices based on the in-out road condition information are used for training the to-be-decided intersections to which the intersection signal lamp decision-making devices are applied. According to the method, intersection signal lamp decision-making devices based on in-out road condition information of an intersection are arranged for a plurality of to-be-decided intersections; and according to the intersection signal lamp decision-making devices for the to-be-decided intersection based on the intersection in-out road condition information, after sand table simulation data training is carried out on the to-be-decided intersection, the phase and phase timing are decided. According to the invention, the global coordination control of signal lamps at multiple intersections can be completed on the basis of intelligent control of a single intersection only by locally adding and collecting the information of the in-out road conditions, complex and poor-effect global training is not needed, and the problem of regional traffic congestion is relieved.

Description

technical field [0001] The invention belongs to the field of traffic control, and more specifically relates to a chain feedback multi-intersection signal light decision-making system and method for entering and exiting road condition information based on entering and exiting road condition information. Background technique [0002] Traffic signal control is the most widely distributed and most frequently used traffic control measure, and intelligent control of signal lights is one of the effective means to solve traffic problems. However, traffic problems are usually not caused by a single local intersection, but by a continuous road or an area containing multiple intersections. Therefore, the global coordinated control of signal lights at multiple intersections must be considered in order to improve regional traffic conditions. [0003] For the intelligent control of signal lights at single intersections, many attempts have been made, especially after the introduction of de...

[0005] Aiming at the above defects or improvement needs of the prior art, the present invention provides a system and method for chained feedback multi-intersection signal light decision-making based on the information of entering and exiting road conditions. It is used in the training of a single intersection signal light decision-making device, and adjusts the state and reward of the algorithm, taking the exit vehicle overflow into account, so as to achieve better training completion, so that the trained intelligent agent can observe the impact of the control strategy of this intersection on the adjacent The impact of intersections, so as to realize the coordinated control of adjacent intersections, and then through the continuous adaptation and adjustment of two adjacent intersections, the overall coordinated control can be adaptively realized, thus solving the complex structure, difficult training and deployment of multi-intersection decision-making systems.
