With the rapid development of economy and society, Intelligent Transport Systems also known as the road traffic information communication system, based on systems engineering, electronics, communications, information, and other high-tech, and have penetrated into the new transportation system of aviation, shipping, rail transport sector. In this paper, there is the basic organizational framework for intelligent transportation, intelligent transportation network proposed model and its data storage structure, and the important influence on optimal path trajectory intelligent transportation planning. This paper analyze intersection road network in the distribution based on computer. Establish ITS can improve after the road network line capacity and service levels, improve environmental quality and improve energy efficiency. There are introduction and overview of the basic concepts of domestic and international development, and proposed disciplinary system model of intelligent transportation systems, and network services model hierarchical model, and a brief analysis a model of meaning. Finally, the system standardization issues and model of the role of standardization briefly introduced
