Intelligent Traffic Management System For The City

In the recent years our country's vehicle holds assumed the geometric series to grow, municipal transportation demand is also along with sharp growth. But at present, the rate of our city transportation infrastructure rise has not been able to meet the transportation need which grows day by day. Traffic jam, the road network use factor is low, the traffic accident increases, the environmental pollution intensifies and so on to become the serious problem which our country municipal transportation faces. The domestic and foreign practices proof, the effective method of solving the municipal transportation question is to raise the traffic control level on the existing traffic infrastructure foundation to achieve fundamentally the goal of solving the question.The Advanced Traffic Management System is one of ITS important subsystems. It applies the transportation information gathering technology, data communication synthesis, transmission technology, electronic control technology and computer processing technology to the traffic control system and the vehicles, to enhance the existing road network use factor, to reduce the road traffic crowded degree and the traffic accident formation rate, to reduce a journey's time is due to the traffic congestion, the accident and so on, and to reduce the oil consumption and the exhaust emission and so on. At present, according to the transportation infrastructure construction situation and the vehicle holds growth condition in the future several, the only way is through the science control method and the management method to alleviate the transportation demand pressure which the vehicles increase creates.The Intelligent Traffic Management System applies precisely the high tech and the high level technology application to enhance the working efficiency of the traffic control system, and to achieve the goal of changing the municipal transportation chaotic aspect. This thesis discusses the composition of ITS and ATMS, also describes the present situation and tendency of ITS and ATMS development in the domestic and foreign, unifies Wuhan the situation to plan and to construct the Intelligent Traffic Management System of Wuhan.At present, the City Intelligent Traffic Management system is the main method of solving our country municipal transportation question, carries on integrated the control and the management to the traffic operation and the facility in the scientific method. This thesis has done the quite comprehensive research to the city intelligence traffic control system, has made the thorough analysis to each subsystem. It mainlyintroduces the transportation detector performance and these technology optimum composition principles;and introduces the intelligence supervisory system composition and the primary control method;and has designed the emergency response system composition and the subsystems function, and mainly introduce the detailed analysis and the research to the most superior-path algorithm and the GPS vehicles locating system. Finally after understanding the city Intelligent Traffic Management System composition and the principle of work, and the domestic ATMS development condition, unifies the Wuhan transportation present situation and the transportation intellectualization technical level, it proposes the Wuhan intelligent traffic management system embryonic form.
