Pedestrian and vehicle separation non-blockage transition region road network

Abstract

The invention discloses a pedestrian and vehicle separation non-blockage transition region road network. The road network comprises more than two same pedestrian and vehicle separation non-blockage transition unit road networks, wherein each pedestrian and vehicle separation non-blockage transition unit road network consists of a cross interchange road, a connected ramp, a main walk way, a flying overpass, a flying tunnel, an upper-pass approach, an upper pass channel, an underpass approach and an underpass channel. The road network has novel concept and scientific structure, has the characteristics of no signal light instruction, no pedestrian or vehicle crossing conflict, no same plane traffic conflict, bridge concealment, instant non-blockage traffic, passing efficiency improvement, accident avoidance, actual floor area reduction, less influence to peripheral urban view, construction cost reduction, construction period shortening and the like, is suitable for road planning construction of urban cities, old urban road reformation and urban road planning construction and reformation, and has wide market application prospect and excellent economical and social benefits.

Description

technical field [0001] The invention belongs to the field of urban road traffic. Background technique [0002] Traffic congestion is a worldwide traffic problem. An important reason for traffic congestion is that the signal light command mechanism of the red light stop and green light at the level intersection has the disadvantage of "one-way driving and three-way parking", which directly leads to a serious decline in the actual traffic capacity of the road. This is because under the command of the traffic light signal, traffic in one direction of the level intersection is at the cost of prohibiting traffic in the other three directions. In this way, the actual continuous traffic capacity of the road is also reduced by at least 75% in the reciprocating stagnation. %. That is, under the command of traffic lights, the actual continuous traffic capacity of the roads at each intersection is only 1 / 4 of the designed traffic capacity of the road, that is, the original design of ...

AI Technical Summary

Problems solved by technology

However, while traditional overpass bridges are three-dimensionally dredging traffic flow without stagnation, there are inevitably problems such as large bridge body affecting cityscape and large area, high construction cost and long construction period. Therefore, it is difficult to popularize at urban crossroads. application

It is shown that a well-functioning overpass costs hundreds of millions of yuan, and the high cost makes people dare not care about it; the bridge-building land of over one hundred acres at every turn makes people look at the bridge; it is a pity that the land in the overpass has not been fully and effectively used; the huge bridge The overall structure is difficult to integrate with the surrounding buildings and landscapes, especially in the reconstruction of old cities, which may constitute damage to the surrounding ancient buildings or natural landscapes

Therefore, it can only make people sigh and feel helpless
