Description
Technical field
The present invention relates to Urban Bridge traffic design technical field, it is specifically related to a kind of city crossing-fiver bridge traffic Landscape Design Method promoting the control of driver's speed, spacing holding capacity, thus realizing the unification of city crossing-fiver bridge coordination of landscape and bridge traffic safety benefit。
Background technology
On the crossing-fiver bridge of city, overspeed of vehicle is general, knocks into the back, collision safety guardrail Frequent Accidents。City crossing-fiver bridge is generally long, short then hundreds of meters, long then thousands of rice。On bridge, traffic safety facilities and view are generally not enough, and environment is dull, and object of reference is few；Driver lacks direction sense, sense of speed, causes general hypervelocity phenomenon。Vehicle travels on bridge, and road speed is high, and following distance is less, when current vehicle is because stopping in emergency or slowing down, very easily causes pursuit-type vehicle not dodge in time, thus causing group generation of car rear-end collision。The domestic statistics to city crossing-fiver bridge accident shows that hypervelocity is major accident reason, and knocking into the back and colliding roadside barrier is major accident form, accounts for total accident more than 60%。
Existing city crossing-fiver bridge landscape setting specific aim is not strong, it is necessary to for cause of accident and Crash characteristics design city crossing-fiver bridge view。View be viewpoint place finding and in brains formed comprehensive eye impression, the crossing-fiver bridge landscape design of existing city often rests on aesthstic aspect, is largely because the cognition to road landscape and only rests on the beautifying of road itself and attached structure thereof。In the planning and designing and evaluation of road landscape, should only not only focus in the aesthstic aspect of road landscape itself, and the functional study of the visually-perceptible aspect of the constitutive characteristic person of being used for of road landscape self should be added。Therefore necessary according to Crash characteristics (knock into the back, hit side wall) and cause of accident (hypervelocity), by promoting driver's identification ability to railing guardrail, front vehicles under different illumination environment, it is specially speed control, spacing holding capacity, to reach the unification of city crossing-fiver bridge coordination of landscape and safety。
Method for controlling driving speed based on edge rate is applied。Edge rate is considered as the very important visual factor affecting speed perception。Edge rate is people when moving, and in space, each point is through the relative velocity of vision periphery。Chinese scholars makes for promoting highway environment perception of velocity by what edge rate " unconscious " carried out speed controlling in traffic, Liu Bing is (Wuhan University of Technology's Master of engineering paper in Master's thesis " speed based on driver's visual perception controls and track keeps study mechanism ", 2008) draw when edge rate is less than 2Hz by psychophysical testing, or during more than 32Hz, driver there will be speed and underestimates, edge rate is when 4Hz～16Hz, speed is created and over-evaluates by experimenter, and wherein edge rate is that 12Hz over-evaluates and reaches more than 30%。
The color impact on traffic safety。Color bleeding is to each corner of road traffic, and for driver, transport information has at least 80% from vision, and color is the easiest perception of vision (its priority level is more than shape, size, content), and directly affects safe driving。Current road mostly generally is Lycoperdon polymorphum Vitt or black, the nervous system of people is had calm effect by Lycoperdon polymorphum Vitt and black, but the Lycoperdon polymorphum Vitt road surface watching dullness for a long time attentively can make driver attention slow up, and brings out fatigue, even drowsy, make the dangerous increase of generation vehicle accident。The scenery of the environment of city crossing-fiver bridge periphery mostly is Lycoperdon polymorphum Vitt with light blue, the color and background contrast of guardrail is only small, so, on the one hand, guardrail can not play vision guide effect, and driver's sense of direction declines, on the other hand, when especially dim light under running at high speed, driver is likely to do not see guardrail or can not correctly judge that the position of guardrail makes distance perspective decline, and causes the generation of vehicle accident (particularly rear-end collision)。
Human eye is different to the sensitivity of different color under different illumination。Research shows that vision is to be completed by the joint activity of eyes, optic nerve and visual centre, and visual system major part is eyes, and eyes are the receptors of vision。It is that light arrives retina via pupil that people experiences the process of the stimulation of light, and the light experienced is conveyed to optic nerve by optic cells different in retina, and stimulation is sent to brain region of interest by optic nerve again。And the optic cell in retina mainly has two classes, one class is rod cell, one class is cone cell, wherein rod cell is distributed in amphiblestroid away from center, low level lighting is worked, act primarily as difference black and white effect, spectrum Green, blue portion is most sensitive, extremely weak stimulation is sensitive；And cone cell is more distributed in foveal region of retina place, high levels of illumination being worked, Main Function is difference color, to yellow in spectrum, red most sensitive, main identify locus and requires to see object observantly。In the crossing-fiver bridge of existing city, view kind is few, and density is low, and color arranges unalterable, very dull, it is not easy to causes driver excited, also easily brings out fatigue driving。
Summary of the invention
