Monitoring System Design, Based On The Traffic Conditions Of The Intelligent Transportation System

Public transport has a large capacity, high efficiency, low cost, save energy and reduce pollution. With economic development and the accelerated process of urbanization, urban traffic congestion, people are becoming increasingly prominent travel inconvenience, a serious impact on urban development and people's living standards. Priority to the development of urban public transport is to improve the transport efficiency of resource use, an important means to ease traffic congestion. Research shows that building an advanced public transportation system, the use of information technology tools to improve public transport operations production management level, for improving the efficiency of urban public transport operations and service quality, reduce management costs, improve public transport market share, development of urban public transport is of great significance. Intelligent transportation system (APTS) is a computer communications, and many other modern high technology, system integration, is the twenty-first century transport system, an important development direction.With the rapid development of urban construction, urban road traffic conditions in real time monitoring has become a major event in the city emergency management and one of the key. At present, real-time road traffic monitoring system, basically sentinel surveillance system. Density of monitoring points and deployment of the deployment location, limiting the scope of monitoring. At the same time, sentinel surveillance means the city can not meet the full range of real-time monitoring of road traffic needs.In this paper, intelligent transportation system based on road traffic conditions of urban real-time monitoring method is to collect public transport vehicles through real-time location and speed data, analysis, public transportation vehicles in the intersection between any two average speed to determine the section method of road traffic conditions. As long as the path to cover public transportation network, can achieve real-time road traffic monitoring. Since driving the bus line is fixed, and the basic coverage of the city's main traffic roads, so intelligent transportation system based on urban road traffic monitoring method can be achieved on the main road round the city' s real-time traffic monitoring. Meanwhile, the public transportation network and traffic demand distribution of significant correspondence between the road with heavy traffic (most is also the focus of monitoring road traffic) and bus lines is relatively large, intelligent transportation system based on road traffic conditions of urban real-time monitoring method access to monitoring data and more accurate.Intelligent transportation system based on urban road traffic conditions based on real-time monitoring method, the paper from the system architecture, data acquisition and processing, network topology, etc., described the public transportation system based on intelligent traffic monitoring system. Meanwhile, the paper also critical subsystem data acquisition subsystem designed in detail, including vehicle intelligent terminal design, database structure, data transmission norms.
