Phase sequence selection and scheme generation type traffic signal phase configuration method and system

Abstract

The invention provides a phase sequence selection and scheme generation type traffic signal phase configuration method and system. Basic information is configured; intersection signal basic phases andintersection signal phase sequences are configured on the basis of the configuration of the basic information; and intersection signal phase schemes can be configured with a scheduling-time period-scheme idea. According to the phase sequence selection and scheme generation type traffic signal phase configuration method and system, a traditional scheme-time period-scheduling signal scheme configuration mode is converted into the scheduling-time period-scheme mode; signal scheme period division and signal phase timing setting of each period are performed based on historical traffic flow data; and therefore, intersection signal scheme timing is effectively assisted, and the error of signal scheme configuration caused by traditional sample calculation and artificial experience modes can be avoided, and intersection traffic signal scheme configuration efficiency is improved.

Description

technical field [0001] The invention relates to a phase sequence selection and scheme generation type traffic signal phase configuration method and system. Background technique [0002] The intersection is the foundation of the urban road network and the "throat" of urban traffic. It is at the core of the urban road network system and is also the traffic bottleneck. The traffic signal control system is the main way of urban traffic control. Therefore, the intersection traffic signal control It is particularly important. Intelligent traffic signal control can effectively improve the efficiency of intersection traffic, alleviate traffic congestion, reduce exhaust emissions, and shorten travel delays. Traffic signal intelligent control requires the configuration of traffic signal characteristic parameters to realize the intersection traffic signal phase configuration. The traditional phase configuration is to collect the traffic flow data at the intersection by experienced pers...

Problems solved by technology

[0006] In this context, the present invention proposes a traffic signal phase configuration method and system based on phase sequence selection and scheme generation, which solves the problem in the prior art that the timing is completely manually set according to experience and lacks a supporting basis; When configuring the scheme, it is necessary to reset the phase sequence and phase of each scheme, and then distribute it to each time period and scheduling scheme. The configuration process is complicated and it is not convenient for subsequent adjustment of signal optimization schemes.
