The invention discloses an intelligent traffic system, which reduces traffic jam, environmental pollution, accident rate and the load of drivers and achieves the aims of ensuring security, improving efficiency and environment and saving energy resources. The technical scheme is that the invention adopts the intelligent traffic system which is formed by a road system composed of a lead-in lane and a totally-closed lane, a GPS positioning system, a 3G or 4G communication system, a control system and automatic travel vehicles. After using the intelligent traffic system, the driver can give up autonomic driving and uses automatic driving controlled by the system to reach the destination. The intelligent traffic system uses advanced information technology, data communication transmission technology, global positioning technology, geographic information system technology, electric control technology and computer processing technology, is a novel transportation system integrating informatization, intelligent and socialization and makes traffic infrastructure exert the largest efficacy.
