摘　　要：交叉路口智能交通监控系统是解决交叉路口交通瓶颈的重要手段.本文首先研究了城市交通智能监控系统网络架构,重点探讨了路口级交通监测与控制平台建设,提出了基于CAN总线的交叉路口交通监控系统的设计与实现方案,结合MSP430单片机完成CAN节点模块硬件设计和软件开发,并对CAN总线上层传输协议进行了开发.通过所构建的最小CAN总线实验系统,验证了基于CAN总线的数据传输及通信协议的可行性、实时性和可靠性.Crossroad intelligent traffic monitoring system is an important measure to solve the bottleneck of crossroad traffic. Firstly, the frame of intelligent traffic monitoring system is set up in this paper, and the crossroad supervising and control system is exactly researched. The monitoring system of crossroad traffic is designed reasonably based on Controller Area Network （CAN）. The design of hardware and software is accomplished on MSP430 SCM, and the communication protocols of CAN＇s transport layer are programmed. At last, a smallest CAN system is constructed, the experiment results of which validated that the system based on CAN is feasible, real-time, effective and dependable.
