Problems solved by technology

[0003] The purpose of the present invention is to aim at the defect of existing urban road traffic structure, thereby provide a kind of flexible, applicable, the split type intercommunication common overpass structure that is used for urban road intersection, is exactly by the design to the traveling route of each direction, combines The special left-turn short road on the ground between the two bridges forms a traffic route network of split interchange overpasses to realize the smooth passage of vehicles traveling in all directions at the intersection

Embodiment 1

[0019] Such as figure 1 The structure shown is a split interchange structure based on a cross-shaped cross structure, including a split one-way common overpass and a cross-shaped intersection formed by two general roads. The split one-way common The overpass is placed above the vertical general road and connects with the horizontal general road.

[0020] Wherein, the split type one-way ordinary overpass is composed of two parallel one-way ordinary overpasses, and the two one-way ordinary overpasses are respectively connected with two one-way lanes of a horizontal general road.

[0021] The two ordinary overpasses have an appropriate distance to move longitudinally from the center line of the horizontal ordinary road to both sides, thereby forming a dedicated left-turning site symmetrical to the center line of the intersecting road. Wherein, the split unidirectional ordinary overpass includes two parallel ordinary overpasses, such as image 3 As shown, the driving directions on two...

Embodiment 2

[0035] Since in the left-turning area in the first embodiment, left-turning vehicles in various directions will be intertwined and knotted in this area, and this situation is suitable for situations with a small traffic volume.

[0036] If the traffic volume in the left-turning area is large, then the left-turning vehicles in the above-mentioned embodiment will be blocked. Therefore, as an improvement of the above-mentioned embodiment, the interweaving area can be lengthened, such as figure 2 As shown, the above-mentioned problems can be solved, or a roundabout is provided at the connection position of the split-type interchange ordinary overpass and the ordinary road, which can alleviate the above-mentioned problem.

[0037] The split type interchange structure of the present invention is formed by two parallel ordinary overpasses, combined with four dedicated left-turn lanes on the ground between the two bridges, and other combined routes; it realizes that vehicles traveling in ea...

Abstract

The invention relates to a split type interchange common overpass structure. A crossroad structure is used as the establishment foundation of the split type interchange common overpass structure. The split type interchange common overpass structure comprises two split type parallel one-way common overpasses and a crossroad, wherein the crossroad is composed of a longitudinal common road and a transverse common road. The split type one-way common overpasses are arranged above the longitudinal common road or the transverse common road. The two parallel one-way common overpasses are connected with two one-way lanes of the transverse common road or the longitudinal common road. A left-turn dedicated site is arranged between the two common overpasses, wherein the left-turn dedicated site is formed in the manner that lanes of the transverse common road or the longitudinal common road connected with the two common overpasses are longitudinally or transversely moved from the center line of the transverse common road or the longitudinal common road to the two sides by an appropriate distance, and the left-turn dedicated site is symmetrical about the central lines of the intersecting roads. The split type interchange common overpass structure achieves that traveling vehicles in all directions of the crossroad travel in own lanes and smoothly pass the crossroad. The split type interchange common overpass structure has the adjusting and guiding functions and achieve infinite circulation of vehicles travelling in the overpass area.

Description

Technical field [0001] The invention relates to an urban traffic road structure, in particular to a split-type interchange structure based on a cross-shaped cross structure. Background technique [0002] At present, in order to solve the urban traffic congestion, a variety of solutions have emerged, roughly in the following situations. The first is that the number of crossing bridges to be built is many, and the erection is relatively high, so that the slope is longer or the slope is larger, the area is wide, and the investment is large, which is unrealistic. The second type is to use a longer viaduct or pull-down trough. Although it is not too high, it only relieves local traffic congestion. The third is to drive by restricted numbers, but as the number of vehicles continues to increase, restricted numbers cannot ultimately solve urban traffic congestion. The last one is the construction of subway or light rail, but it can only solve the general direction of unblocking, but ca...
