Problems solved by technology

However, most of the existing research on regional traffic signal control systems only focuses on the control algorithm, ignoring the software performance of the control system itself. Moreover, due to commercial and other factors, they are relatively closed, and often can only be connected to the manufacturer's own signal control equipment. Affects real regional traffic signal control effects

Abstract

The invention provides a traffic signal control system building method based on stream computing and a control system. The method comprises: building a software development environment of a data access module used for receiving, caching, and forwarding traffic signal data to a distributed stream computing system via a data acquisition module and designing the data access module; building a software environment of the distributed stream computing system used for receiving and processing the traffic signal data; designing a topology of the distributed stream computing system; and submitting JAR packets to each node of the distributed stream computing system according to the topology. According to the method, the distributed and open type traffic signal control system with low delay and high fault tolerance can be realized.

Description

technical field [0001] The invention belongs to the field of distributed control, and in particular relates to a method for building a traffic signal control system based on flow calculation and a control system. Background technique [0002] The urban traffic system is a natural complex open giant system, and the emerging traffic flow has many complex characteristics such as uncertainty, time-varying, hysteresis, etc., which makes the traffic system control research face great challenges. As one of the important development directions to alleviate urban traffic congestion, regional traffic signal control aims to use vehicle detectors to perceive regional traffic conditions, and through a series of calculations, analysis and decision-making of regional traffic signal control algorithms, and finally through networked roads The signal machine changes the operation of signal lights to realize the intervention and control of regional traffic. [0003] Since the first centralize...
