Description

Single-layer barrier-free full interchange system at crossroad

Technical Field

Relates to a barrier-free full-intercommunication traffic facility at a plane crossing intersection of an urban road.

Background

The automobile usage amount is increased day by day in the road traffic operation, and the existing road traffic facilities can not meet the development requirements, so that the urban road traffic is blocked, and the inconvenience of the citizens going out or a plurality of potential safety hazards are caused. The existing road traffic facilities can not get rid of various problems such as the lane conflict between vehicles and pedestrians, the cross driving between vehicles, the waiting restriction of traffic lights and the like from the beginning. Only a single bridge or tunnel is usually used to alleviate the traffic congestion problem; or a big ear turning ramp or a multi-layer multi-element overpass is adopted, and a large amount of land occupation and investment are occupied; furthermore, traffic lights are arranged at the intersection to be restricted, so that vehicles in all directions stop and jam in a red light restricted area, the vicious cycle state of 'jam-release-jam' is aggravated, and the road traffic efficiency is greatly reduced. Or dummy pedestrian overpasses or pedestrian underpasses are adopted to set artificial obstacles for pedestrians to cross roads, or the basic rights of pedestrians to cross roads are neglected due to the great advantages of automobiles in modern road traffic operation, so that the congestion phenomena of intestinal obstruction, chinese type road crossing and the like can be caused. The method is mainly used for solving the problem of urban road traffic jam, and aims to give priority to road traffic and human-oriented convenience for pedestrians to go out and reduce the use amount of automobiles; the road traffic facilities are accessible, and the vehicle passing efficiency is improved.

Disclosure of Invention

The invention aims to solve the technical problem that a crossroad single-layer barrier-free full interchange system is designed at a plane crossing crossroad of an urban road, underground passages, ground turning ramps, pedestrian overpasses or pedestrian tunnels, zebra stripes and traffic lights are not arranged, pedestrians can safely, conveniently and omnidirectionally pass through the barrier-free pedestrian passages on the ground plane of the crossroad, and the use amount of automobiles is reduced; vehicles pass through the arc-shaped road-crossing bridge and the M-shaped upward-crossing bridge at the crossroad, are in barrier-free cross straight running and pass through the rhombus-shaped overhead turning ramp assembly in an all-round barrier-free turning mode, so that traffic jam is reduced, and the passing efficiency is improved. The method has the advantages that the method can realize the all-round barrier-free passing of pedestrians and vehicles only by adding a three-dimensional layer on the ground at the crossroad, reduces the grade separation layers, saves the occupied area and the investment, and breaks through the traffic bottleneck that pedestrians can pass the road on the same ground plane of the crossroad without barriers and left-turning vehicles can pass the crossroad without interweaving in a single layer and without barriers and can be unblocked at the crossroad.

In order to solve the problems in urban road traffic, the invention designs a single-layer barrier-free full interchange system at a crossroad, which comprises a longitudinal road and a transverse road, wherein the longitudinal road and the transverse road are crossed into a crossroad section, sidewalks are arranged on two sides of the longitudinal road and the transverse road, the sidewalks on two sides of the transverse road directly run straight on a crossroad ground plane without barriers to cross a road, and the sidewalks are intersected and communicated through two barrier-free pedestrian passages on the transverse road ground plane on the crossroad ground plane; the barrier-free pedestrian passage is arranged on the road surface under the M-shaped overhead bridge approach arch and is used for pedestrians to pass through the road without barriers at the crossroad; the M-shaped overhead bridge is arranged on an overhead arc-shaped cross road on a central ground plane transverse road of the cross road, so that straight-going vehicles can pass through without barriers, and the bridge approach arch ensures that pedestrians pass through the road without barriers; the arc-shaped cross-road bridge is arranged on the upper layer of a longitudinal road of a cross center road surface and is used for straight-going vehicles to pass through without barriers; the combination of the M-shaped ascending and descending bridge and the arc-shaped road-crossing bridge on the ground solves the problems that straight vehicles at the crossroad have no obstacle and vehicles turn back to turn back have no obstacle, and breaks through the trouble that pedestrians pass the road on the same ground plane of the crossroad without obstacle; the rhombus-shaped elevated turning ramp assembly is arranged on the upper layer of a cross center road surface for left-and-right turning vehicles to pass through without interweaving, all-round and barrier, overcomes the defect of outer winding land, reduces the grade of the flyover, saves the occupied area and investment, and breaks through the traffic bottleneck that the same three-dimensional grade single-layer flyover above the crossroad turns left without interweaving and barrier. The rhombus-shaped elevated turning ramp assembly is only combined with the arc-shaped road-crossing bridge to ensure that vehicles at the crossroad have no barriers and are communicated with each other completely. The rhombus-shaped elevated turning ramp assembly, the M-shaped overhead bridge and the arc-shaped road bridge are all combined in an embedded manner at the same three-dimensional level of the crossroad, and the longitudinal and transverse spans are all within the span of the arc-shaped road bridge. The longitudinal road and the transverse road are respectively provided with an accessible turn back on the ground of the crossroad, or can be used as an underground square vehicle access of the crossroad center, and the crossroad pedestrian rotary island is an underground square pedestrian elevator safety exit.

By adopting the single-layer barrier-free full-interchange system at the crossroad, pedestrians can safely, conveniently and omnidirectionally pass through the road without barriers on the same ground plane of the crossroad, a green channel is really laid for urban citizens to select public bicycles to ride in a green manner, and the using amount of automobiles is reduced; the longitudinal and transverse spans are all within the span of the arc-shaped bridge span, and the floor area of the conventional intersection is reduced by 25-50%; vehicles pass through the crossroad in an all-around barrier-free mode, traffic jam is reduced, and passing efficiency is improved by multiple times. Only one three-dimensional layer is added on the ground at the crossroad, so that the pedestrian and the vehicle can pass through the crossroad in an all-round and barrier-free way, the interchange layers are reduced, and the occupied area and the investment are saved. The technical measures realize the non-interweaving, non-obstacle and full intercommunication of the vehicles and the pedestrians at the crossroad, and break through the traffic bottleneck that the pedestrians pass the road on the same ground plane of the crossroad without obstacles and the left-turning vehicles pass the crossroad without obstacles and are unblocked. Embodies the new concept of human-oriented pedestrian and vehicle harmonious intersection. The method can be widely applied to the reconstruction of crossroads and the construction of busy intersection traffic hubs in urban centers. The urban traffic jam treatment method is environment-friendly, efficient and unique in urban aesthetic impression, and can effectively treat chronic traffic jam.
