基于交通流量自适应控制的路口子系统

Intersection Subsystem Based on Adaptive Traffic Flow Control

在经济快速发展、道路建设不足等多重压力下,城市交通负担越来越重.在现有的资源条件下,如何提高道路资源的利用效率和道路的通行效率是缓解交通问题的重要途径.本文以设计一种基于交通流量自适应控制的路口子系统为目标,首先分析、研究了交通管控系统的相关算法和相关信息系统的现状,在综合现有系统的基础上,设计了一个交通管控系统的体系结构,系统包括路口子系统、区域中心和信息与控制中心等3部分.通过路口子系统实现交通流数据的实时采集和路口本地的智能控制;设计并实现了路口子系统的检测方案,路口子系统的数据采集和本地的智能控制是云数据存储,以及实时的交通信息平台发布的关键,同时对于实现多个路口的协调管控具有重要的意义.

Under the pressure of rapid economic development and insufficient road construction,the urban traffic burden becomes increasingly heavier.Under the existing resource conditions,how to improve the utilization efficiency and traffic efficiency of roads is an important way to alleviate traffic problems.In this study,with an intelligent signal intersection based on a traffic flow control subsystem as the goal,we firstly analyze the related algorithms of the traffic control system and the present situation of the information system.Based on the existing system,we design the architecture of the traffic control system,comprising the intersection subsystem,regional center,as well as information and control center.The intersection subsystem realizes the real-time acquisition of traffic flow data and the local intelligent control of the intersection.The detection scheme of the intersection subsystem is designed and implemented.The data acquisition and local intelligent control of the intersection subsystem are the keys to cloud data storage and real-time release from the traffic information platform,and it is of great significance to the coordinated control of multiple intersections.
