Description
Technical field
The present invention relates to road traffic field, be specifically related to cross-road passages for pedestrians and control method thereof that a kind of hommization high-level efficiency is current.
Background technology
Along with the theory of people-oriented sustainable development is rooted in the hearts of the people, pedestrian traffic, as the important component part of urban transportation, comes into one's own gradually.Cross-road passages for pedestrians are the important steps that connect whole pedestrian system, are the important channel that pedestrian jaywalks, and are also the main region that pedestrian and motor vehicle clash.In recent years, China big city is along with vehicle possess amount increases rapidly, traffic problems are more and more outstanding, and pedestrian and motor vehicle contradiction highlight, and occurred unique phenomenon of " Chinese style is gone across the road ", Chinese style is gone across the road and is referred to that everybody goes across the road and often ignore the existence of traffic lights, think that the law does not punish everybody, as long as psychology and behavior that the pugil people that gathers together enough just can go across the road, being on the rack of both having caused that pedestrian goes across the road is complete, make again motor-driven vehicle going difficulty, man-vehicle interface is more complicated.Simultaneously due to traffic lights setting and the wide reason of road, often occur that pedestrian cannot complete the disposable street of crossing in the signal period, particularly at large-scale signal cross crossing, cause pedestrian to expose to the open air for a long time in the middle of road, this not only serious impact vehicle current, also form great road safety hidden danger, how solving people's car contradiction has become very important problem simultaneously.
At present, cross in the facility of street and be mainly divided into two classes: a class is plane cross-road passages for pedestrians, as crossing, walker signal lamp etc.; Another kind of is three-dimensional cross-road passages for pedestrians, as overpass and underpass etc.Due to reasons such as construction costs and convenience degree, it is still general that plane is crossed street mode.Thereby how to solve conflicting of pedestrian and vehicle, ensureing the safety of pedestrian's street crossing, the design that does not affect again traffic efficiency Guo street facility is very necessary.But in traditional pedestrian facility crosses street planning and designs, put undue emphasis on the traffic efficiency of motor-driven traffic, to pedestrian, caused very large inconvenience, the waits for too long of pedestrian's street crossing, studies show that according to investigations on the one hand, and the domestic pedestrian's street crossing stand-by period generally surpasses 100s, what have has even surpassed 120s, considerably beyond the patient time of pedestrian, cause pedestrian to produce anxiety, increased the rate violating the regulations in street; Green light is not green on the other hand, and the not red phenomenon of red light is also very outstanding, even if show green light, right-hand rotation vehicle is not controlled by traffic lights to cause it often to clash with pedestrian, increase pedestrian's street crossing risk.
The blank the earliest of center safety island appears at Britain, and crossroad, 6 in incity, police office, Liverpool in 1862 is provided with pedestrains safety area.1903, the father William Yi Nuo of traffic safety is in write < < traffic rules > >, for the first time " safety area " called to " center safety island " (pedestrian refuge), from then on, " center safety island " promoted widely and used all over the world.Center safety island is set on road, becomes and internationally generally adopt and confirm as safe auxiliary pedestrian's street crossing measure.Some developed countries have formed comparatively perfect achievement arranging of pedestrian center safety island, as the < < pedestrian safety devices of the U.S. designs > >, Zelanian < < sneakernet circuit planning and facilities design guide > >, the pedestrian center safety island of Britain arranges standard, Germany < < walking facilities design guide rule > >, the facilities design planning guide rule > > of < < People's Bank of China of Australia etc. the setting of centering heart safety island have given detailed standards and design standard.China starts late in this respect, and minority provinces and cities have also attempted dissimilar People's Bank of China's center safety island design.Wherein main design specifications has < < Code for planning design of transport on urban road > >, < < arterial street, Shanghai City cross-road passages for pedestrians planning and design guide rule > >, the planning of < < urban road pedestrian crossing facilities and the design specifications > > of Hangzhou, but simple requirement has been done in the basic setup that is only centering heart safety island.The center safety island form of the intersection that current China is main has three kinds: 1) the center safety island of floor line form; 2) fence type center safety island; 3) desk-top center safety island.These center safety islands have only been considered to provide a region of temporarily stopping to pedestrian, to pedestrian's the traffic capacity and safety, vehicle current and the form arranging and position and auxiliary facility inconsiderate, cause its security effectiveness low, service efficiency is not high, and has a strong impact on original traffic efficiency.
In order to ensure pedestrian's safety and the traffic capacity of road, the research for pedestrian's street crossing both at home and abroad also has a lot.In the research of stand-by period of pedestrian's street crossing, find, Chinese pedestrian is 90s the maximum endurable stand-by period, but pedestrian is only 50s in the stood time of middle center safety island; Preventing that pedestrians disobeying traffic rule from crossing in the measure in street research and finding, effective method is countdown and city assistant policeman; At the parting of the ways in the arranging of cross-road passages for pedestrians, find that right-hand rotation canalization facility can reduce conflicting of right-hand rotation car and pedestrian, the safety of increase pedestrian's street crossing.
Disorder, the long period signal of signalized crossing and pedestrians disobeying traffic rule are crossed street three and have been formed a vicious cycle, cause crossroad access chaotic.Thereby in the planning and design of the center safety island of vehicle flowrate and the larger crossroad of flow of the people, need to solve rational pedestrian within the scope of the stand-by period, pedestrian can safety the street problem of crossing fast, simultaneously again can support vehicles traffic efficiency at the parting of the ways.
