The car of a normal travel, abrupt, the buzzer inside the car rings, the indication screen of windshield shows before, ahead produces traffic accident, decelerate goes slow, the attention is safe. The driver shifts to an earlier date decelerate, bypass accident area. Travel arrives next course, "Ahead is bent " , " the accident sends an area easily " , " speed limit 60 kilometers are horary " the road transportation information that waits for car ahead hints often to the driver through speech, character, and see the label of road side traffic that shows these information and alterable information board when, the driver is in into bamboo already bosom. Abrupt, car enters mist area, the vision of car identifies a system to show, apparent distance is less than 50 meters. The driver is not nervous, because, be based on intelligent highway magnetism the driveway of revulsive technology keeps auxiliary drive, offerred driveway for the driver the function such as early-warning of danger of driveway of guiding of line of sight, deviate. Enter the city zone, face have the way that block up, have the aid of enters the car of Internet to hold information system directly, in real time trends traffic is believed breath is how-to below, car is fast safety reachs destination.

The concept becomes reality eventually

Afore-mentioned one screen that attends to often be described with all sorts of forum, lecture in paper before, below the effort of our country researcher, had become reality. On the plenary meeting of world of traffic of the 14th intelligence that held at Beijing 2007, be in test site of traffic of highway of the Ministry of Communication, research center of technology of project of system of national intelligence traffic (center of abbreviation country ITS) the staff member revealed their research in respect of intelligent car route to the whole world achievement, the concept becomes reality eventually.

Mention intelligent traffic, cannot leave intelligent car way idea of this one core. The research forward position that system of intelligent car route is project of traffic of current world intelligence, car and automata domain, it with foundation of highway intelligence melt into, abide by road infrastructure and car to carry a system to coordinate cooperative concept, compositive application is contemporary the technical implementation car such as communication, information, automata, sensor is auxiliary drive those who reach specific requirement to fall is automatic drive, reduce the traffic accident that factitious element causes, the security that improves highway system and moving efficiency. National ITS center begins to undertake dogging study to its from 2000, already formed at present include intelligent highway porcelain revulsive, car keeps automatically safe and driveway control, auxiliary drive the achievement of whole set technology of the own intellectual property that waits for a technology.

In this one domain, national ITS center undertook a series of scientific research projects, include national science and technology to tackle key problem special subject " intelligent highway technology dogs " , country 863 tasks " structure of information of intelligent road system and environmental perception and reframe the technology studies " , " the road intelligence label that is based on car route to coordinate and perceptive technology research " , " be based on extensive to be in the road establishment of network technology and calamity information are collected and shirt-sleeve " , the Ministry of Communication western project of science and technology " development of revulsive and safe support system reachs new-style highway magnetism demonstrative application " . Additional, the center still was assumed " intelligent carriage system gets used to cruise to control systematic function oneself requirement and detect method " and " deviate of driveway of intelligent carriage system calls the police systematic performance demand and detect method " two occupation standard. In the meantime, be based on afore-mentioned research, the center was begun in Xinjiang " safety of the car that sweep snow is auxiliary drive demonstrative system " application sets an example.
