一、引言 在城市智能交通控制系统中,经常存在着在一个控制系统中各控制设备通讯协议互不兼容的问题,且各厂家通讯协议互不开放,这样,由于各项设备的通讯协议的不兼容,给系统集成造成困难。 智能交通控制系统是一个具有随机性、模糊性和不确定性的复杂系统。交通控制是通过信号控制器来实施的。在交通控制系统中,一般来说,交通信号控制器可以完成三方面的任务:一是按照给定
I. INTRODUCTION In the urban intelligent traffic control system, there often exist problems that the communication protocols of each control device in one control system are incompatible with each other, and the communication protocol of each manufacturer is not open to each other. In this way, since the communication protocol of each device is not Compatible, causing difficulties for system integration. Intelligent traffic control system is a complex system with randomness, fuzziness and uncertainty. Traffic control is implemented by the signal controller. In traffic control system, in general, traffic signal controller can accomplish three tasks: First, according to given
