Description
Technical field
The present invention relates to traffic safety technical field, a kind of expressway exit Downgrade Ramp inducible system is refered in particular to
Design method.
Background technology
Ring road is arranged to meet with other unicom road traffic demands in the case where ensureing the closed characteristic of highway
Interface channel is unique road that highway is converted to land-service road traffic.Expressway traffic safety is road traffic peace
A big problem in complete, however expressway exit ring road Frequent Accidents.
According to both at home and abroad to expressway traffic safety accident statistics research shows that：The accident quantity of exit ramp is public in high speed
Accounting in the whole traffic accidents quantity of road is about 40%, and the main forms of exit ramp accident are：It hits
Structure (about 50%), vehicle rear-end collision (about 20%), slide-out (about 20%).Vehicle becomes in highway main line track into subtracting
During speed is further separated into exit ramp, driver may be because not enough vision area visuals field and good induction information,
Vehicle need to carry out the complex operations such as changing Lane, deceleration shunting and weaving in short time, short distance, and in addition traffic flow is rushed
It is prominent detailed, speed dispersion is big, to increase the driving task of driver, it is higher in turn result in driver psychology load, moreover
Most of exit ramp is curved slope Combination Design, and bend and ramp illusion are serious, in addition undesirable induction information, and driver is easy
The decision to make mistake is done, the possibility of accident generation is considerably increased.Therefore, effective traffic engineering facilities induction information can
Moment reminds, is vigilant driver, ensures good rate controlling and enough induction informations, will be effectively improved existing expressway exit
The safe condition of ring road.
Expressway exit ring road inducing installation has certain Research foundation, the use of exit ramp chevron alignment sign and
Setting also has certain theoretical foundation.Mainly there is multiplelevel exit pre- in the design of existing expressway exit ring road traffic engineering facilities
Accuse mark, plus-minus Fast Moving Vehicle Lane pre-warning mark, confluence warning mark etc..And in ring road region, existing existing induction mark setting
Method is just started setting up from ring road minor radius, and the height of most of settings is small, in the form of a single, and visibility is poor, can not pierce
Swash Driver Vision and psychology, can only be found by driver in entrance ramp eloquence, especially at night, reflective function is poor,
Do not play inducing action, driver easily can not be depending on recognizing the approximate location of ring road mouth；Existing ring road region track edge line
For solid white line, setting effect is single, nighttime driving person can not well judge the position of exit ramp with it is linear；It is existing anti-
It hits bucket setting and is intended merely to the nose shunting of warning ring road region and easy collision prevention function.In addition, existing expressway ramp area
Domain retroreflective traffic safety devices setting shows slightly insufficient, is unfavorable for the safety traffic of vehicle.
Reflecting material and technology also reach its maturity simultaneously, and use of the reflex reflection technology on traffic affiliated facility is very
Generally, cost is gradually lowered.The maximum technical characterstic of reflex reflection is both the irradiation brightness for taking full advantage of automotive headlamp, is led to
The reflecting material crossed on traffic engineering facilities surface is reflective, and driver is made to perceive, and optimizes the visibility of driver, makes driver
Make correct decision.The design of expressway exit ring road inducible system considers that bend inducing installation setting principle, application are converse
Technology is penetrated, and from Driver Vision demand, the information combination of the setting more sizes of multifrequency and linear inducing installation, enriches outlet
Ring road visual environment, auxiliary driver correctly judges and control transport condition, effectively reduces expressway exit ring road traffic thing
Therefore probability of happening.It is largely all based on subtracting for speed control in domestic expressway exit ring road Improvement for traffic safety
The guardrail Anticollision Measures of fast measure and passive protection lack improvement principle of the systematicness from driver safety demand.
Therefore there is an urgent need for the visions and psychological needs according to driver, and active induction is blended with passive protection, makes full use of reflex reflection
Material technology, improves the vision visibility of driver, and the inductivity of Improving Expressway exit ramp ensures expressway exit
Ring road operation security.
Invention content
In view of the above problems, the present invention provides a kind of expressway exit Downgrade Ramp inducible system, it is public for high speed
Way outlet ring road bend with gradient illusion is serious, inductivity is poor, driver easily misses exit ramp, exit ramp speed is excessively high
Feature, by chevron alignment sign, the reflective aluminium sheet of yellow, reflector, Anti-collision barrel and the combination settings for vibrating graticule, by more
