Multi-scene vehicle priority adaptive traffic signal control system and its working method

Abstract

The invention relates to the technical field of traffic signal control and discloses a multi-scene vehicle priority adaptive traffic signal control system and a working method thereof. The system creates bus priority control suitable for multiple scenarios (including bus lanes and mixed lanes), not only ensures bus priority to the utmost extent in the event of normal traffic flow at an intersection, but also avoids deteriorated traffic circulation at the intersection due to the bus priority, ultimately improves the operational efficiency of the entire traffic, and has high economic and socialbenefits. In addition, special vehicle priority control can be carried out for the occurrence of special vehicles at the target intersection, the absolute priority can be given to the special vehicles, and the demand of the special vehicles for passing through the target intersection without stop can be satisfied as much as possible so as to achieve timely special treatment for special cases.

Description

technical field [0001] The invention relates to the technical field of traffic signal control, in particular to a multi-scenario vehicle priority adaptive traffic signal control system and a working method thereof. Background technique [0002] Traffic signal control is one of the important methods for urban traffic organization optimization. The existing traffic signal control methods for buses passing through intersections are mainly divided into passive priority control, active priority control and adaptive priority control. Among them, the passive priority control is mainly based on historical data such as passenger travel patterns, bus departure frequency, and driving speed, in the traffic signal control scheme (i.e., the signal configuration executed by the intersection signal machine) executed by the intersection and designed offline. time scheme, including signal cycle, green signal ratio and phase sequence optimization, etc.) to give priority to buses, thereby reduc...
