城市交通协调控制综述

城市交通信号控制是城市交通管理的一个极为重要的环节.从最初简单的机械信号装置到今天广泛应用系统工程理论和计算机技术,其间经历了一个从简单到复杂、从低级到高级的发展过程.本文对这一过程中系统的模型化方法,控制方案的演变、进化等进行了历史回顾;介绍了一些已得到世人公认的交通控制系统.例如,TRANSYT,SIGOP,SCOOT,SCATS等.同时,对前人在理论上的一些探索也进行了介绍和评价.在此基础上,对我国在这一领域的发展方向,提出了看法.

A Review of Coordinated Urban Traffic Control

The signalling of urban traffic is a very important part of urban traffic management. Ittakes people quite a long time to reach today's system engineering and computer based efficientsignal control system from the early safty oriented signal control. The evolution of modellingtechniques and control software during this process is reviewed in the paper, with particularcomments on some of the well-known systems like TRANSYT, SIGOP and SCATS. Based onthis review the authors' personal view on the further research directions in this field for Chinais given.
