Abstract

On the basis of an existing intersection, one longitudinal or transverse main lane is excavated through an overhead road or an underpass to form a double-layer intersection. An upper layer and a lower layer respectively allow vehicles and pedestrians in the transverse and longitudinal directions to pass; the height of left-turning and right-turning lanes on the upper layer accords with that of an intersection on the upper layer; left-turning and right-turning lanes on the lower layer and an intersection on the lower layer are on the same level; in order to save the floor area of the left-turning and right-turning lanes, the opposite left-turning and right-turning lanes are connected and then ascend or descend to be combined with the main lane; traffic signal lamps and pedestrian signal lamps indicative of straight-going and left-turning are respectively arranged on the upper layer and the lower layer, and pedestrian stairs are arranged at four corners of the intersections respectively to connect the intersections on the upper and lower layers and are used by the pedestrians; the pedestrians go across a crosswalk in parallel to the vehicles on the upper layer or the lower layer.

Description

Half grade separation double-layer cross crossing

Technical field

The present invention relates to the road traffic field, especially the overpass bridge field in the urban traffic.

Background technology

Along with the continuous lifting of people's living standard, automobile has been the vehicles indispensable in the daily life, and along with the continuous increase of automobile quantity, the traffic pressure of urban road, especially crossroad etc. have the traffic main artery of traffic lights more serious.Existing crossroad is not that the overpass bridge that traffic lights are exactly full intercommunication is set, traffic lights cause traffic congestion easily, long by the time, waste the precious time and the energy, and the overpass bridge of full intercommunication no doubt can pass through the crossing fast, but general floor space is big, the cost height, and the overpass bridge of building full intercommunication in each crossroad obviously is unrealistic.The present invention combines the advantage of intercommunicated overpass and lamp control crossroad, realizes that on the basis of few land occupation resource vehicle and pedestrains safety ground pass through the crossroad fast.The present invention takes full advantage of the soil of existing crossroad, has solved this difficult problem dexterously.

Summary of the invention

On existing basis, crossroad, utilize overhead or down wear wherein vertical or horizontal A-road of excavation, make it become double-deck crossroad.Top one deck and following one deck are born the current of horizontal and vertical automobile and pedestrian respectively, the left-hand rotation on upper strata is consistent with the crossing height on upper strata with right-turn lane, the left-hand rotation of lower floor and right-turn lane then with lower floor's same level in crossing, for the floor space of changing trains or buses about saving, in opposite directions left-hand rotation with climbing or descending and A-road merge again after right-turn lane is connected.Existing crossroad is that four direction all is equipped with traffic lights, and the present invention is divided into two four traffic lights, and one deck and following one deck arrange traffic lights and the walker signal lamp of keeping straight on and turning left respectively in the above.Existing pedestrian's zebra stripes all are " well " font and are drawn in the crossroad, and the present invention is divided into anyhow each two to it to be drawn in crossroad up and down, and need not pass through major trunk roads, only need pass through left turn lane and get final product.At crossing four jiaos pedestrian's stair are set respectively and connect two-layer crossing up and down, for pedestrian's use, allow the pedestrian on the upper strata or lower floor's zebra stripes parallel with automobile go across the road.Respectively having 30 seconds with the transit time at each crossing, original lamp control crossing is example, four direction is respectively wanted 120 seconds by the circulation in a crossing, each direction must wait after current 30 seconds again can pass through afterwards in 90 seconds again, and the pedestrian must wait 90 seconds more too and just can pass through again after current 30 seconds.And the present invention was example in 120 seconds with a circulation equally, was similarly in turn left (in opposite directions) under 30 seconds the situation, then all can be used for keeping straight in all the other 90 seconds, and the transit time of craspedodrome is 3 times of original transit time.The pedestrian is as the same, except the time of vehicle left-hand rotation in 30 seconds, all can pass through zebra stripes, and increase the handling capacity of crossroad so greatly in all the other 90 seconds.

Description of drawings

Accompanying drawing 1 is overhead crossing of the present invention plan view.

Accompanying drawing 2 is worn intersection plane figure under of the present invention.

Specific implementation method

On the basis at existing lamp control crossing, adopt method overhead or that excavation is worn down to build vertical or horizontal major trunk roads, two-layerly up and down be respectively the road that direction is intersected, original like this crossroad just becomes the lamp control crossing of a bilayer, left turn lane on the straight way in opposite directions link to each other with right-turn lane again through access bridge or under wear the ramp and be connected on its corresponding A-road, change trains or buses about bilevel respectively with bilevel A-road at same horizontal plane, two-layer traffic lights that arrange respectively up and down, and the pedestrian zebra stripes parallel with the craspedodrome road, build pedestrian's stair in four corners at crossing respectively and go across the road for the pedestrian by the crossing of upper strata (overhead) or lower floor (wearing down) is continuous.When supposing that craspedodrome signal lamp green light is bright (up and down two layers can be simultaneously, with the actual conditions adjustment), except bilevel left turning vehicle, all vehicles and pedestrian can normally pass through, and when left rotaring signal lamp green light is bright, then only allow the vehicle pass-through of (vehicle of right-hand rotation can determine whether to pass through by actual conditions), vehicle and the pedestrian of craspedodrome wait green light, successively circulation.

Claims

1. half grade separation double-layer cross crossing is characterized in that existing crossroad access signal lamp and pedestrian's zebra stripes are divided into two, one group of traffic lights is set separately at bilevel crossing, the vehicle and the pedestrian that control upper strata or lower floor respectively pass through, and two-layer crossroad arranges two zebra stripes parallel with major trunk roads respectively up and down.

2. four jiaos of two-layer crossing arranged pedestrian's stair connection two-layer crossing up and down about half grade separation double-layer cross crossing is characterized in that, went across the road for the pedestrian.

3. half grade separation double-layer cross crossing is characterized in that the left turn lane on upper strata is consistent with the crossing level height on upper strata with right-turn lane, the left turn lane of lower floor is consistent with the level height of lower floor with right-turn lane, and the left turn lane of levels and right-turn lane be not at same horizontal plane.
