Since the implementation of the reform and opening up , China's gross national product , with the rapid development of the national economy sustained rapid growth, people's living standards continue to improve . In the process of economic development , the number of transport growth , no small pressure on road traffic . Today , road transport facilities more on the demands of economic development , the role of constraints on the development of the national economy , in the form of development \Increasingly serious traffic congestion, frequent occurrence of safety accidents , and how to resolve this issue , has formed a long-term problem of troubled . Highway monitoring system is part of the intelligent transport system , it gives a feasible solution for the problem . Expressway monitoring system at home and abroad , the paper outlines the status of the study , an analysis of the purpose and effect of the highway monitoring system ; conducted in-depth analysis of the needs of the highway monitoring , clear monitoring system of monitoring platform system and functional requirements ; during the monitoring system design , research system design principles , to monitor control strategy design ideas and generate implementation; highway monitoring system and carried out a detailed functional design , and architecture of the monitoring system design, network architecture design , software architecture design ; understanding of the composition and function of the monitoring system hardware , provides the basis for the design and development of the monitoring system . At the same time focused on the automatic incident detection algorithms for video surveillance . Finally, in the context of the highway , the use of computer vision technology and digital image processing technology research to explore some algorithms to detect moving vehicles , such as automatic detection of the projected movement of vehicles , incident detection , automatic tracking , the vehicle obstacle avoidance, speeding, lane changing , slow , stop , traffic jams and events such as the implementation of automatic and rapid detection , and the statistics of the traffic flow, average speed and other traffic parameters . Other similar monitoring system design experience for reference .
