Method and device for traffic phase adjustment based on road traffic state

Abstract

The embodiment of the invention provides a method and a device for traffic phase adjustment based on a road traffic state. Vehicle passing data at upstream and downstream intersections in a road section are acquired; according to identifiers of N passing vehicles and the time for passing across the upstream and downstream intersections, the parking times of the N passing vehicles are determined; according to the parking times of the N passing vehicles, the passing state in the road section is determined; and when the passing state in the road section is determined to be a congestion state, the traffic phase of the upstream and downstream intersections in the road section is adjusted according to the parking times of the N passing vehicles. As the passing state in the road section is determined according to the vehicle passing data at the upstream and downstream intersections in the road section acquired in real time, on one hand, the test cost is reduced, and on the other hand, the passing state in the road section is determined more comprehensively and objectively. When the traffic state in the road section is poor, the problem existing in the traffic phase of the upstream and downstream intersections in the road section can be timely determined, adjustment can be carried out, and congestion in the road section can be effectively alleviated.

Description

technical field [0001] The embodiments of the present invention relate to the field of intelligent traffic control, in particular to a traffic phase adjustment method and device based on road traffic status. Background technique [0002] With the mature development of arterial coordination technology and its application in the field of urban road traffic signal control, more and more urban main roads apply coordination control technology, hoping that as many vehicles as possible can pass through each intersection without stopping on a green light. Theoretically, arterial coordinated control technology is a means that can reduce the number of stops and effectively alleviate road congestion. However, after the implementation of arterial coordination, an objective evaluation method is needed, which can reflect the traffic status of the coordinated road section in real time and provide a comprehensive analysis of the coordination scheme. Make adjustments. For the evaluation met...
