Description
Technical field
The invention belongs to the traffic safety technology field, be specifically related to a kind of spontaneous session lamp method to set up that is used to reduce speedway rear-end collision and reduction speedway rear-end collision intensity of setting about from driver's visual perception characteristic.
Background technology
Vehicle rear-end collision is important accident pattern with collision fixture accident.2010, be informed of a case altogether 3906164 of road traffic accidents of the whole nation.Wherein, the death toll that speedway has an accident, causes goes up 5.2%, 4% on year-on-year basis respectively.See from the deadly accident that speedway takes place, the 40.3%th, trail the collision accident, the 21.9%th, collision fixture accident, and in the majority with dilly and truck rear-end collision.At present; The major measure of China's Highway Control spacing is for to be provided with one group of space confirmation sign at every about 10km; This indicates that one group is formed by 5, and putting in order of they is followed successively by the distance marker of rear end collision, space confirmation and 0m, 50m, 100m, and the plate face is rectangle.This kind space confirmation sign is used to remind the driver that front and back car spacing is carried out understanding to a certain degree.This kind method can be reminded spacing to the driver, but can not guarantee the control vehicle of driver's active and the spacing of front truck, does not reach the spacing control effect of expection.So, be necessary to find out from the purpose of control vehicle on highway front-and-rear vehicle distance and reach the method for driver's ACTIVE CONTROL and front truck spacing of making.
Front-and-rear vehicle distance is the important factor in order of driver's forward direction collision prevention.Traffic flow theory research shows that the driver is relevant with driver's reaction, front-and-rear vehicle distance with car collision prevention behavior, a high proportion of rear-end collision and with the collision accident explanation of building, the driver possibly exist perception, the misjudgment of reaction mistake and spacing.Visual information is the important foundation in the perception and the understanding world.In vehicularized today, the driver in its information of obtaining, is visual information as one type of important crowd more than 80%.The driver mainly obtains traffic environment information through vision, then its danger is judged, makes a strategic decision, is taken action.The relevant authority's report of the U.S. points out, 90% accident is that the mistake by the people causes; Have 80% above accident and motor vehicle driving relating to persons at least in China.
Therefore; Visual information from the driver; The visual information influence factor of research driver spacing perception in the turnpike driving process; Analyze visual signature, vehicle operating characteristic, the perception spacing-actual spacing difference characteristic of driver in the turnpike driving process; Explore and propose based on driver's visual information help improving the scientific and reasonable method that the perception spacing is induced, to avoiding vehicle on highway to knock into the back and collide the fixture accident, it is significant to improve express way driving safety.
Summary of the invention
The technical problem that the present invention will solve is: a kind of spontaneous session lamp method to set up that is used to reduce the speedway rear-end collision is provided.
The present invention solves the problems of the technologies described above the technical scheme of being taked to be: a kind of spontaneous session lamp method to set up that is used to reduce the speedway rear-end collision, and it is characterized in that: it may further comprise the steps:
