The longitudinal road (1) and the transverse road (2) are respectively provided with an obstacle-free return elbow on the ground of the intersection. By adopting the measures, the barrier-free full intercommunication of vehicles at the crossroad and barrier-free road crossing of pedestrians are realized. The traffic bottlenecks that pedestrians pass the road without obstacles on the same ground plane of the crossroad and left-turning vehicles pass the crossroad without obstacles and are unblocked are broken through.

Description

A single-layer barrier-free full-interchange interchange system at a crossroad

technical field

It involves barrier-free and fully interoperable traffic facilities at urban road intersections.

Background technique

The use of automobiles in road traffic operation is increasing day by day, but the existing road traffic facilities can not keep up with the development needs, which makes the urban road traffic not smooth and the vehicles are congested, causing inconvenience to citizens and even many safety hazards. From the very beginning, the current road traffic facilities have been troubled by many problems, such as vehicles competing with pedestrians, vehicles intersecting with vehicles, setting traffic lights to wait for traffic restrictions, and many other problems. Usually only a single span bridge or tunnel is used to alleviate traffic congestion; or the use of "big ears" turning ramps or multi-layer overpasses takes up a lot of land and investment; what's more, it is helpless to set traffic lights at intersections to limit traffic, resulting in Vehicles in all directions stop and congest the red light restricted area, so that the vicious cycle of "congestion-release-congestion" is intensified, which greatly reduces the efficiency of road traffic. Or the use of pedestrian bridges or pedestrian underpasses is equivalent to falsehood, setting up artificial barriers for pedestrians to cross the road, or ignoring the basic rights of pedestrians to cross the road due to the great advantages of automobiles in modern road traffic operations, resulting in "intestinal obstruction" or "intestinal obstruction". Chinese-style crossing the road" and other congestion phenomena. The root of solving the problem of urban road traffic congestion is to give priority to people-oriented road traffic to facilitate pedestrian travel, reduce car usage; make road traffic facilities barrier-free, and improve vehicle traffic efficiency.

Contents of the invention

The technical problem to be solved by the present invention is to design a single-layer barrier-free all-interchange system at urban road crossroads, without underground tunnels, ground turning ramps, pedestrian bridges or pedestrian tunnels, zebra crossings, and traffic lights , Pedestrians cross the road safely and conveniently through the barrier-free pedestrian passage on the ground level of the intersection, reducing the number of cars used; The elevated turning ramp combination is omni-directional barrier-free turning, reducing traffic congestion and improving traffic efficiency. Only using the ground at the intersection and adding a three-dimensional layer can realize the all-round barrier-free passage of pedestrians and vehicles, reduce the level of the interchange, save the floor area and investment, and break through the barrier-free crossing of pedestrians on the same ground level at the intersection and the left-turning vehicles. Barrier-free traffic bottlenecks at intersections.

In order to solve the problems in the above-mentioned urban road traffic, the present invention designs such a single-layer barrier-free full-interchange interchange system at crossroads, which includes longitudinal roads and transverse roads, and the longitudinal roads and transverse roads intersect to form cross sections, and the There are sidewalks on both sides of the longitudinal road and the transverse road, and the sidewalks are intersected by two barrier-free pedestrian passages on the transverse road on the ground level of the intersection; For straight-going vehicles barrier-free passage; the M-shaped supine-span bridge is set on the horizontal road in the center of the cross road for the non-barrier-free passage of straight-going vehicles and to ensure that pedestrians can cross the road without barriers. The M-shaped supine-span bridge replaces the underground tunnel and makes the function Diversification; the rhombus-shaped elevated turning ramp assembly is arranged on the upper layer of the cross center road surface for all-round barrier-free passage of turning vehicles. The rhombus-shaped elevated turning ramp combination can ensure barrier-free and full intercommunication of vehicles at intersections only by combining with arc-shaped span bridges. The rhombus-shaped elevated turning ramp assembly, the arc span bridge and the M-shaped upward span bridge are all mosaic combinations at the same three-dimensional level at the crossroads. The longitudinal road and the transverse road are provided with barrier-free turns on the ground of the intersection respectively.

Adopting the above-mentioned single-layer barrier-free full-interchange interchange system at crossroads can realize safe, convenient and all-round barrier-free crossing for pedestrians on the same ground level at the crossroads, paving the way for urban citizens to choose public bicycles for green cycling. Reduce the use of cars; the vertical and horizontal spans are all within the span of the arc-shaped span bridge, reducing the area occupied by conventional intersections by 25-50%; vehicles can pass through the intersections in all directions, reducing traffic congestion and improving traffic efficiency several times. Only using the ground and adding a three-dimensional layer at the intersection can realize the all-round barrier-free passage of pedestrians and vehicles, and reduce the level of interchanges to save floor space and investment. The above-mentioned technical measures have realized the barrier-free full intercommunication of vehicles at the intersection and the barrier-free crossing of pedestrians, breaking through the traffic bottlenecks of pedestrians crossing the road on the same ground level at the intersection and left-turning vehicles at the intersection without barriers. It embodies the new concept of humanistic transportation that puts people first and harmoniously blends pedestrians and vehicles.

detailed description

As shown in Figure 6, the longitudinal road 1 and the transverse road 2 intersect to form a cross road section, and both sides of the longitudinal road 1 and the transverse road 2 are provided with sidewalks 6, and between the sidewalks 6 on both sides of the road is a motor vehicle lane (two-way in the figure). Ten lanes, which can also indicate the increase or decrease of the traffic lane), the sidewalk 6 passes through four pedestrian roundabouts 7 on the same ground level at the intersection and intersects with two barrier-free pedestrian passages 8 on the transverse road 2, and the pedestrian passage 8 turns around 2 u Arranged side by side on the outer ground plane, passing under two identical arc-shaped approach bridges 4a extending from both ends of the M-shaped overhanging bridge 4. It is the same width as the sidewalk 6, for pedestrians to cross the road without barriers in all directions on the ground level of the intersection.

The arc span bridge 3 set on the longitudinal road 1 is a two-way four-lane bridge with a limited traffic height of 4.3m (different height limits can be set depending on the road conditions). Pass the M-shaped upward-span bridge 4, and set up a barrier-free turning back 1u, a horizontal barrier-free sidewalk 6 and a bus stop 9, and the turning back 1u is set on the ground plane outside the horizontal sidewalk 6 at the crossroads (the ground level can be arbitrarily lowered according to the road conditions) Set the required height for restricted traffic), the height limit is 3.5m (the height limit can be set differently depending on the road conditions), and the arc-shaped span bridge 3 access and uphill sections have a standard gradient of 8/100.
