According to the Ministry of Communications recently announced national highway network planning, from 2005 to 2030, the state will spend two trillion yuan, 5.1 million meters of new highway, so China's highway mileage of 8.5 million km. Highway traffic monitoring system as part of the intelligent transportation system, not only can improve the average speed of vehicles during peak periods, increase the amount of traffic during peak periods, to reduce the level of traffic congestion and vehicle delay time; also can greatly reduce traffic accidents and ensure traffic safety. fuel economy and reduce vehicle wear and shorten the transport time, reduce pollution, and to play a motorway fast, safe, comfortable and efficient role. Has a very significant economic, social and environmental benefits. Universal importance of engineering researchers at home and abroad. Actually involved in the project as the basis, on the basis of the traffic data of highway traffic monitoring system, you see a lot of literature, and learn from the previous description of highway traffic data, analysis, processing of successful experience in the research. A deep understanding of and derive the relationship between the basic parameters of the freeway traffic flow, set out to design a highway traffic monitoring system data warehouse and transportation information cube ROLAP model. From the time dimension, location dimension, dimension and on the natural environment, downstream traffic conditions dimension different angles, different sides of the traffic information data analysis. SQL Server 2005 Analysis Services analytical tools to slice, cut, drill and other operations, traffic information cube ROLAP from constraints found that the impact of vehicle speed and lane control program. Create data mining structures and data mining models use data mining tools in SQL Server 2005 Analysis Services data warehouse highway traffic monitoring system, the historical data collected in the actual system, comes with Analysis Services decision tree mining algorithm, constraints affect vehicle speed and lane control program were analyzed and constraints as well as the impact of vehicle speed and lane control program. Finally, according to the conclusions of the analysis, processing, combined with the standards and specifications of the vehicle speed limit of the natural environment, traffic control strategy panorama. So that highway traffic management personnel can use the traffic control strategies panorama, analysis of real-time traffic information collected on traffic information acquisition device, draw highway vehicle travel speed or driving control program, release the control program to the current analysis section of the intelligence The board, in order to achieve the purpose of the induction, management and control of the highway road vehicle.
