Miniature anti-clogging fast passing bridge

Abstract

The invention discloses a miniature anti-clogging fast passing bridge, which comprises a first-layer pavement (1) and a second-layer deck (2) erected right above a crossing, wherein the first-layer pavement (1) is provided with a two-way motor vehicle linear driving passage (11) and a non-motor vehicle passage (12); the second-layer deck (2) is provided with motor vehicle leftward turning, rightward turning and turn-around passages (21), (22) and (23); signal lamps in linkage control are arranged on the first-layer pavement (1) and the second-layer deck (2). The non-motor vehicles, pedestrians, straight driving vehicles, leftward turning vehicles, turn-around vehicles and rightward turning vehicles are in the passing path space separation, so that the vehicle and pedestrian passing rate iseffectively improved. The miniature anti-clogging fast passing bridge has the advantages that the occupied area is small; the structure is simple; an approach bridge is short; the engineering investment is low; the bridge is suitable for being used in crossings of middle-sized and small cities.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a miniature anti-clogging fast-passing bridge. Background technique [0002] With the popularity of family cars in China, traffic jams have become a norm, especially in urban core areas. Intersections are very congested during rush hour, and vehicle traffic is very slow. Through the observation and analysis of traffic conditions at the intersection, the key points that affect the speed of vehicles and pedestrians passing through the intersection are found: [0003] One is the traffic conflict between the left-turning motor vehicle and the opposite straight-going motor vehicle [0004] The second is the traffic conflict between non-motor vehicles and motor vehicles turning left [0005] The third is the traffic conflict between right-turning motor vehicles and non-motor vehicles and pedestrians [0006] Fourth, traffic conflicts between U-turn motor vehicles and oncoming motor vehicles ...

AI Technical Summary

Problems solved by technology

[0003] One is the traffic conflict between the left-turning motor vehicle and the opposite straight-going motor vehicle

[0004] The second is the traffic conflict between non-motor vehicles and motor vehicles turning left

[0005] The third is the traffic conflict between right-turning motor vehicles and non-motor vehicles and pedestrians

[0006] Fourth, traffic conflicts between U-turn motor vehicles and oncoming motor vehicles

[0007] These four traffic conflicts have directly caused slow or even blocked intersections.

[0008] There are two main modes of traffic control at urban intersections. One is the intersection where turning left and going straight pass at the same time. In this way, various traffic conflicts and contradictions are prominent, and it is easy to form traffic jams; the other is time-sharing control for turning left and going straight. Passing through the intersection, this method solves the first and fourth conflicts above, and the anti-blocking ability has been improved to a certain extent, but because it adopts time-sharing control, the waiting time of vehicles passing is artificially lengthened, and the passing efficiency is very low

Intuitively, the best way to solve intersection traffic is to build an interchange bridge. However, due to its large area, complex structure, multiple levels, long auxiliary roads, and large project investment, the scope of application is limited to the surrounding areas and cities of large and medium-sized cities. Larger street intersections, and at the same time cause varying degrees of inconvenience to pedestrians and non-motorized vehicles

The existing traffic control at intersections has been developed to time-sharing control, and there is no way to improve traffic efficiency and safety; however, if you want to build an overpass in the city center, you will face demolition and high investment, and the demand contradiction is prominent. Therefore, a new type of traffic control is needed Improve the traffic efficiency of the current intersection without demolition
