Three-special flyover

Abstract

The invention discloses a three-special flyover, which is used for urban road crossroads, has four directions of A, B, C and D, and comprises a pedestrian interchange, a non-motor vehicle interchange and a motor vehicle interchange, wherein the pedestrian interchange comprises two pedestrian cross roads, two pedestrian flyovers, and a ramp, the non-motor vehicle interchange comprises two high-span connecting bridges and ramps thereof and two half-cross platforms and ramps thereof, the motor vehicle interchange comprises two ground straight lanes, two high-span straight bridges and ramps thereof and one elliptical high-span turntable bridge and ramp thereof, the elliptical high-span turntable bridge surrounds the high-span straight bridges, the high-span connecting bridges and the pedestrian overpass cross the half-cross platforms and the ground straight lanes, the half-cross platform strides across the pedestrian cross road, the total structure floats up by 6.5 meters, the pedestrian and non-motor vehicle passing space is 2.5 meters, the motor vehicle passing space is 5.5 meters, the non-motor vehicle traveling is facilitated, environmental protection is achieved, zero crossing and zero mixed traveling among pedestrians, non-motor vehicles and motor vehicles are achieved, the lane is special, passing is safer, and passing efficiency is higher.

Description

technical field [0001] Embodiments of the present invention relate to an overpass, in particular to a three-special overpass in which a pedestrian overpass, a non-motor vehicle overpass and a motor vehicle overpass can operate safely at the same time. Background technique [0002] With the development of society, the number of social vehicles keeps increasing, and urban roads are overwhelmed. Especially during commuting time, urban roads run at full capacity, road vehicles are congested and disorderly, and urban parking spaces are scarce. Non-motor vehicles will travel more frequently, and special lanes should be provided for non-motor vehicles to prevent traffic accidents caused by vehicles crossing and mixing. [0003] There are three common ways to travel on urban roads: motor vehicles (including private cars, buses and trucks), non-motor vehicles (including human-powered bicycles, electric bicycles and electric motorcycles) and pedestrians. Currently, there are no non-mo...

AI Technical Summary

Problems solved by technology

[0003] There are three common ways to travel on urban roads: motor vehicles (including private cars, buses and trucks), non-motor vehicles (including human-powered bicycles, electric bicycles and electric motorcycles) and pedestrians. Currently, there are no non-motor vehicles at urban road intersections. Motor vehicle-only lanes and traffic lights are not set for non-motor vehicle-only passing time. There is a barrier between pedestrians and pedestrians. It is difficult to solve the problem of pedestrians, non-motor vehicles and motor vehicles passing quickly and safely at the same time. Most of the overpasses have Safety risks of driving at height

At intersections, in order to pursue travel efficiency, non-motorized vehicles, pedestrians, and motorized vehicles often intersect in disorder, causing traffic accidents to occur from time to time, and the sense of travel safety is very low
