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。
Urban traffic signal control is an extremely important part of urban traffic management. From the very first simple mechanical signaling devices to today’s widespread use of systems engineering theory and computer technology, during which one has experienced a simple to complex, from low to high development process. This paper reviews the systematic modeling methods, the evolution and evolution of control schemes in this process, and introduces some traffic control systems that have been recognized by the world. For example, TRANSYT, SIGOP, SCOOT, SCATS and so on. At the same time, some predecessors’ theoretical exploration has also been introduced and evaluated. On this basis, we put forward our views on the development direction of our country in this area.
