Abstract

In order to resolve the problem of traffic congestion the present invention provides an intersection vehicles and pedestrians underground stream-splitting system. Said system is characterized by that under the ground surface two layers of vehicles left-turn underground lanes and pedestrian subway. The left-turn vehicle can be gone into the left-turn underground lane along the downwards ramp of bridge approach of intersection, when it is run to exit, said left-turn vehicle can be run along the upwards ramp bridge approach and gone onto ground surface.

Description

The underground separate system of intersection vehicle and pedestrian

Technical field the utility model is a kind of intersection vehicle and the underground separate system of pedestrian.

Background technology

Be the transport solution congestion problems, usually need to build a large amount of overpass bridges, but build overpass bridge take spatial surface big, consume constructional materialss such as a large amount of cement, steel, it is many to drop into construction fund, and also very serious to the destruction of appearance of the city integrated environment etc.At present, cross traffic facilities can be divided into following a few class substantially: 1. full face of land plane.2. full-overpass type.3. half grade separation type.Though these facilities are still being brought into play huge effect in actual life, along with the development and the progress of society, various vehicles are on the increase all deficiencies and the drawback that shows above means of transportation.At first, whole plane type crossing mainly is made up of forbidden red light, fair row green light and is being controlled traffic.Because when vehicle turns left, have a strong impact on the current of opposite through vehicles, so a lot of crossing has increased turn left fair row and forbidden lamp again.Though solved of the influence of left-hand rotation car like this, but each travel direction all increased the waiting time of twice to other through vehicles.The whole plane type also comprises the carousel-type crossing that does not have traffic lights control, and the crossing of this type of free adjustment at random in more than the vehicle and the stream of people, is the multiple point of traffic accident.Second kind is full-overpass type, and this seemingly embodies a kind of sign of transportation modernization.But it except needs take wide surface area, drop into a large amount of construction funds, consume outside the constructional materialss such as a large amount of cement, steel, for the big and medium-sized cities that taken on a certain scale, particularly for city with a long history, time-honoured, the style and features in overpass bridge outward appearance and city is very inharmonious, and the many building operations difficulty around the construction overpass bridge also will be removed sometimes are big, the cycle long, cost is very high.The third is half grade separation type, and it comprises by the face of land and overhead, the face of land and the semi-underground craspedodrome overpass bridge that do not intersect.The bridge on the ring of Beijing three for example.No matter be full-overpass bridge or half overpass bridge; though played very positive effect aspect crowded at transport solution; because they all need long access bridge, left-hand rotation bridge toward contact the needs great circle that makes a circulation to the right, so these two kinds of bridges also are huge to environment damage and to the consumption of resource.The main line resemble Chang'an street for example, if overpass bridge is on the ground all built at each crossing, the result is unthinkable.

Summary of the invention

The present invention proposes a brand-new solution: the underground separate system of intersection vehicle and pedestrian.

The present invention addresses the above problem the technical scheme of being taked: it is genuine that two-layer vehicle left-hand rotation is set below the face of land, and the walkway.Left turning vehicle will comprise when kart and bicycle will walk to the crossing that also the road travels earlier to the line that turns left, enter genuine inlet then, turn left along descending access bridge admission passage.Arrive ground along the upward slope access bridge when walking to outlet.This system need not wait for promptly left turning vehicle can directly to pass through, even also more convenient than keeping straight on.So the crossing on ground just has only keep straight on fair row and forbidden two states, makes the vehicle of all directions and pedestrian all reduce by 2/3 stand-by period.In addition, left-hand rotation climb and fall access bridge is designed to the shifting stage be made up of member, the row as the celebration activity of reviewing troops in case of necessity can be lifted its lower end with ground with power-equipment and be flushed, the cancellation fair row state that turns left.This system has also designed the walkway parallel with bicycle, guardrail is arranged to guarantee safety between sidewalk and the cycleway.The walkway also can add escalator, avoids the stream of people's crowding phenomenon that causes because of the width restriction.Intersection in the middle of the two-layer up and down sidewalk also is provided with lower channel, and the pedestrian can select outlet and whereabouts arbitrarily.The intersection of closing on of two-layer up and down automobile passage and cycleway is provided with interconnection, as the escape way of the traffic accident that meets accident.

The invention has the beneficial effects as follows: 1. floor space is little, frugally table space.2. owing to rely on the support of native stone around the underground passage need not column; The access bridge member is short, so will save constructional materialss such as cement, steel in a large number.3. overall cost and duration are approximately 1/2 of the full-overpass type in ground.4. system is built in underground anti-seismic performance and will improves greatly.5. vehicle and pedestrian's stand-by period can shorten 2/3, can effectively reduce the pollution to air of energy consumption and exhaust emissions.6. system is built in underground urban environment and the monolithic architecture style and features of not influencing.7. after setting up the underground separate system of this intersection vehicle comprehensively, also can reduce because prevent congested in traffic phenomenon vehicle supervision department and have to set up many one-way roads and no left turn crossing, cause the time that Vehicle By-pass brings and the waste of the energy.It is the effective way of alleviating the such arterial traffic crowded state in Chang'an street for example.
