Description
Technical field
The present invention relates to Design of Traffic Safety field, crossing, be specifically related to a kind of combination area of city and country traffic circle traffic safety devices and method for designing thereof.
Technical background
Section, crossing Frequent Accidents. Crossing be Vehicular turn intensively, be the battleground of various traffic flows. Vehicle probably mutually squeezes, touches, hits during by crossing, easily causes the generation of traffic congestion and traffic accident; In the ratio of the shared traffic accident in each section of whole nation statistics, near accident crossing and in region, crossing has accounted for 64% of total number of accident, and the positive accident bumping against accounts for 23%, and average every accident just has 0.39 people dead or severely injured; What bumped against side accounts for 46%, and average every accident just has 0.24 people dead or severely injured; Knock into the back bump against accounted for 12%, average every accident just has 0.42 people dead or severely injured; The accident casualties number of scraping is lower, and the accident casualties number bumping against on stationary object accounts for to such an extent that ratio is large. From analysis on accident cause, the accident ratio that the reason of automobile driver causes is 61%, and pedestrian's reason accounts for 21%, and the ratio that bicycle accounts for is 12%. The improper reaction of automobile overspeed and automobile driver is the main cause causing the accident, and pedestrian affects the also larger ratio of occupation ratio.
Highway crossing means of transportation imperfection, the environmental quality of low-light (level), causes highway multiple without letter control crossing accident. Because existing highway is used by pedestrian in a large number as villages and small towns internal passageway, but any pedestrian safety devices is not almost set, traffic control device also imperfection mostly, cause collision fixture and pedestrian accident multiple, there are some researches show, high 2.3 times than on urban road of the pedestrian's POD having an accident on ordinary highway, fatal accident rate is also high than wanting city. All highway crossings are all without road lighting, low visibility, and external research shows, evening, the death rate of accident in the situation that there is no illumination exceeded 3 times of left and right than daytime.
Method for controlling driving speed based on edge rate is applied. Edge rate is considered to affect the very important visual factor of speed perception. Edge rate is people while moving, and in space, each point is through the relative velocity at edge, the visual field. Chinese scholars is carried out making for promoting highway environment perception of velocity of speed control in traffic " unconscious " by edge rate, Liu Bing is (Wuhan University of Technology's Master of engineering paper in Master's thesis " speed of a motor vehicle control based on driver's visual perception and the research of lane keeping mechanism ", 2008) show that by psychophysical testing working as edge rate is less than 2Hz, or while being greater than 32Hz, driver there will be speed to underestimate, edge rate is in the time of 4Hz～16Hz, experimenter has produced and has over-evaluated speed, and wherein edge rate is that 12Hz over-evaluates and reaches more than 30%.
At existing combination area of city and country traffic circle traffic safety devices imperfection, under the environment of low-light (level), be difficult to ensure driver to barrier in traffic circle and street pedestrian accurately depending on recognizing.
Summary of the invention
