Description
Technical field
The present invention relates to road sign or the technical fields of traffic signal devices, and in particular to a kind of reduction apparatus for roadway,
IPC code is E01F9/047.
Background technique
In recent years, with Chinese society expanding economy, road quality classification is constantly promoted, and city private car quantity surges, city
Traffic accident on city's road also becomes increasingly conspicuous.On many urban roads in China, mainly due to motor vehicle, non-motor vehicle, row
People mixes that row is serious, and the awareness of safety of pedestrian and driver are poor in addition, causes that branch and community, there are serious friendships on school periphery
Logical security risk.In order to reduce the motor vehicle speed of community's road and its peripheral path, the more and more places in China are used
Similar Hesperian traffic calming measure.
Measure one of of the deceleration strip as limiting vehicle vertical travel speed, now common deceleration strip are in mound shape, are broken
Face pattern has 4 kinds: sine curve, arc-shaped, parabola and fold-line-shaped, positioned in street center or being extended to entire street width
Region；Deceleration strip 6-10cm high, is configured at a distance of 100-150m, alternate to cause vision attention with yellow black；Slow down
Band generallys use rubber material, is fixed on road surface by steel nail.Deceleration strip is realized by influencing the driving psychology of driver
Slow down.When vehicle passes through deceleration strip with higher speed, violent vibration can be passed to via vehicle body and seat from tire and be driven
People is sailed, vertical curve can produce the acceleration of a vertical direction, generate strong physiological stimulation (including vibratory stimulation and view
Feel stimulation) and Psychological stimulation.Physiological stimulation promotes driver to generate strong sticky feeling, and Psychological stimulation is then deepened
The dangerous doubt of driver further reduced driver to the sense of security of road environment.Under normal conditions, driver thinks
Non-comfort is bigger, and vehicle safety is smaller, i.e., the sense of security is smaller.Therefore, the setting of deceleration strip can reduce driver's row
The desired value of the vehicle sense of security and riding comfort promotes driver's selection when observing the alternate appearance of deceleration strip yellow black
Lower desired speed.Under desired speed guidance, driver will actively drive vehicle and be approached and led to lower running speed
Cross deceleration strip.
Deceleration strip played an important role containment traffic accident, also achieve in the industry at home in recent years very
Big approval.But since deceleration strip impersonalityization designs and proves, higher level has not yet been reached in comfortable this respect.Specifically
For, because the space on existing deceleration strip protrusion road surface is excessively high (6-10cm), the steel nail on deceleration strip is really up to the mark, and vehicle is from deceleration strip
When crossing, vibration causes certain impact, certain damage can be caused to vehicle compared with strong, not to driver and passenger's bring
Comfort sense is excessively strong.
Currently, requirement of the road user to deceleration strip is no longer limited in this lowest level of safety, but increasingly
Concern uses the comfort of deceleration strip.Therefore, how deceleration strip is improved in terms of comfort, being allowed to more hommization is
The problem of a urgent need is researched and solved.
Summary of the invention
The present invention provides a kind of flexible energy-absorption type deceleration strip, is examined with solving conventional deceleration strip in design comfort aspect
Consider less, cause to cause certain harm to vehicle when automobile passes through deceleration strip, gives driver and passenger's bring sticky feeling mistake
In strong problem.The present invention also provides a kind of flexible energy-absorption type deceleration strip construction technologies, to solve the peace of existing deceleration strip
The problem of dress method cannot be matched with this flexibility energy-absorption type deceleration strip.
