Abstract
The invention provides a self-illumination road lamp setting method for reducing the rear-end accidents on an expressway. The method comprises the following steps of: 1) setting self-illumination road lamps according to a gradual-change edge rate designing mode on the lane of the road section with high risk or good chance of rear-end accidents on the expressway; and 2) selecting an OLED (organic light emitting diode) illumination device with adjustable illumination brightness for the illumination device of the self-illumination road lamp. According to the invention, the gradual-change edge rate designing mode is specifically designed, and sensitive edge rate self-illumination road lamps are arranged on the lane entering the road section with high risk of rear-end accidents on the expressway based on the visual perception edge rate of a driver, so that the subjective edge rate perception of the driver is improved, the speed perception is enhanced, the speed expectation is reduced, and the driver controls the driving speed of the vehicle of the driver and keeps the driving speed to reduce the rear-end accidents on the expressway, thereby comprehensively improving the driving safety on the road section with high risk or good chance of rear-end accidents on the expressway.
Description
Technical field
The invention belongs to traffic safety technology field, be specifically related to a kind of set about from driver's Visual Perception Characteristics for reducing speedway rear-end collision and reducing the spontaneous session lamp method to set up of speedway rear-end collision intensity.
Background technology
Vehicle rear-end collision and collision fixture accident are important accident patterns.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 respectively 5.2%, 4% on year-on-year basis.The lethal accident occurring from speedway, the 40.3%th, trail 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 speedway control spacing is for to arrange one group of space confirmation mark at every about 10km, this mark one group forms 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 plate face is rectangle.This kind of space confirmation mark is used for reminding driver to carry out understanding to a certain degree to front and back car spacing.This kind of method can be reminded spacing to driver, but can not ensure the control vehicle of driver's active and the spacing of front truck, do not reach the spacing control effect of expection.So, be necessary to find out and reach the method that makes driver's ACTIVE CONTROL and front truck spacing from controlling the object of vehicle on highway front-and-rear vehicle distance.
Front-and-rear vehicle distance is the important factor in order of driver's forward direction collision prevention.Traffic flow theory research shows, 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, driver may exist perception, the misjudgment of reaction mistake and spacing.Visual information is the important foundation in perception and the understanding world.In vehicularized today, driver, as an important class crowd, in its information of obtaining, more than 80% is visual information.Driver mainly obtains traffic environment information by vision, then to its danger judge, decision-making, action.The relevant authority's report of the U.S. points out, 90% accident is to be caused by people's mistake; Have 80% above accident and motor vehicle driving relating to persons at least in China.
Therefore, from driver's visual information, the visual information influence factor of research driver spacing perception in turnpike driving process, analyze visual signature, vehicle operating feature, the perception spacing-actual spacing difference characteristic of driver in turnpike driving process, explore and propose the scientific and reasonable method that is conducive to improve the induction of perception spacing based on Driver Vision information, to avoiding vehicle on highway to knock into the back and colliding fixture accident, improve express way driving safety significant.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of for reducing the spontaneous session lamp method to set up of speedway rear-end collision.
