Design scheme for existing road jam dredging and smoothness system of urban center district

Abstract

The invention discloses a design scheme for an existing road dredging and smoothness system of an urban center district, belongs to the field of road traffic engineering, and is an innovative scheme for the existing necessary intersection of the urban center district to realize interchange and road network dredging and smoothness. The system consists of elements including a small overpass, a pedestrian non-motor vehicle shallow culvert, a motor vehicle multifunctional multi-path shallow transfer culvert, a grade crossing turning ramp and the like; according to each differential element of the existing engineering environment of a construction field road network, various intersection road network forms can be assembled through optimizing. The small overpass can guide traffic flow to efficiently go in different spaces; the left turning (or back turning in the middle of the path) of a vehicle on the intersection is finished via the motor vehicle multifunctional multi-path shallow transfer culvert; the pedestrian non-motor vehicle shallow culvert isolates the contact of people and vehicles, and therefore, people can conveniently and safely go through the shallow culvert; the grade crossing turning ramp provides an innovative approach for the reform and upgrade of a traffic way. A scheme is characterized in that modular and componentized design construction is highlighted, and a better, faster and more economic construction feature is specific so as to be favorable for popularization.

Description

Technical field: [0001] This scheme is suitable for the construction and renovation of necessary road intersections in the existing urban center area to achieve interchange, road network to achieve orderly traffic, clear and smooth traffic control, and optimize the planning, design, and construction of new road networks in new urban areas. It belongs to the road field of traffic engineering. Background technique: [0002] At present, the increasing traffic congestion in domestic cities has become normalized. It has greatly slowed down the rhythm and efficiency of the orderly operation of the society, caused an immeasurable consumption of relevant social resources, seriously restricted the development of society, and the problem of congestion needs to be solved urgently. However, the main shortcomings of the current traffic congestion control technology and the current situation are: [0003] 1) The old level crossing road network is still used in the road network in the ce...

AI Technical Summary

Problems solved by technology

[0003] 1) The road network in the central areas of each city still uses the old level crossing road network, and many of the congestion control measures adopted are also in the mode of road level crossing with little innovation, and it is difficult to see results in congestion control

[0004] 2) Occasional small-scale overpass schemes fail to fully integrate with the existing common urban road conditions and field constraints. The large volume and random number of floors, and the scale of the scheme exceed the original control boundary or space of the site, causing land acquisition and demolition and related industries. The problem of resistance and barriers is not practical

[0005] 3) The vast majority of designs are only in the nature of framework or conceived schemes, and the realized technology and construction design are insufficiently considered, and the construction, materials and methods that meet the requirements of fast, efficient and economical are not clear, and the incomplete and insufficient design restricts the construction decisions of relevant parties and implement using

[0006] 4) The way and difficulty for pedestrians and non-motorized vehicles to travel on the overpass and under the deep culvert remain, and there is a lack of transformative technical countermeasures; pedestrians and non-motorized vehicles compete with motorized vehicles at level crossings, seriously affecting normal traffic

[0007] 5) The complex traffic reality needs to focus not only on a certain intersection management office, but also on the basis of this point to look at the relevant road line, and then focus on the whole area of ​​the city or a comprehensive road network system management plan to have practical value. and technology to be corrected and established

[0008] 6) The old technology is rarely involved and innovated in the treatment of intersections and roads that are suitable for the existing narrow space and environmental constraints of the city, and the unblocked traffic control of the road network, and the practical projects of systematic transformation are even rarer.
