Embodiment Construction
[0064] An overpass, in the case of vehicles traveling on the right, includes right-turn lanes A, B, C, and D on the ground layer outside the complete circular lane, a complete circular lane on the ground, arranged in a counterclockwise direction outside the complete circular lane and one end The four roads A, B, C, and D at different points on the periphery of the complete circular lane are directly connected respectively, and are composed of 8 kinds of underpassing lanes. , B to D down-travel lane, B turn left to under-travel lane, C to A down-travel lane, C left-turn under-travel lane, D to B under-travel lane, D left-turn under-travel lane to form, the above 8 kinds of down-travel The through lane undercuts in a full circular lane. The A, B, C, and D right-turn lanes on the ground floor are direct ramps, and the eight underpass lanes are semi-direct ramps. The headroom height of the eight kinds of underpassing lanes is 2.5 meters, and the longitudinal slope of the underpas...

The invention relates to an overpass and a traffic method. Under the condition that vehicles keep to the right, the overpass comprises a full annular traffic lane and eight kinds of down-penetrating lanes, four lanes of a lane A, a lane B, a lane C, a lane D are arranged on the exterior of the full annular traffic lane and one ends of the four lanes are directly connected with the different points of the periphery of the full annular traffic lane correspondingly. The eight kinds of down-penetrating lanes are composed of the A-to-C down-penetrating lane, the A left-turning down-penetrating lane, the B-to-D down-penetrating lane, the B left-turning down-penetrating lane, the C-to-A down-penetrating lane, the C left-turning down-penetrating lane, the D-to-A down-penetrating lane and the D left-turning down-penetrating lane. The eight kinds of down-traversing lanes penetrate down in the full annular traffic lane. The clearance height of the eight kinds of down-penetrating lanes is 2.5 meters. The traffic method of the overpass comprises the following steps that in the vehicles that prepare to pass through an intersection, the vehicles with the height of less than 2.0 meters run on the corresponding down-penetrating lanes and pass through the intersection, the rest of the vehicles run on the full annular traffic lane and pass through the intersection.
Description
technical field [0001] The invention relates to an overpass bridge and a traffic opening method. Background technique [0002] With the development of social economy, more and more vehicles appear in cities, including vehicles of different sizes, styles and models, and more and more urban overpasses appear in cities. There is a kind of overpass called cloverleaf overpass , Cloverleaf Interchange: A circular ramp is used for left turns, a direct-connected ramp is used for right turns, and a four-fork intercommunicating interchange in the shape of a cloverleaf. Although the cloverleaf-shaped overpass greatly facilitates traffic and improves traffic efficiency, its disadvantage is that it occupies a large area, which greatly affects its extensive use in the city center. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an overpass that has a lower height and a smaller area than the cloverleaf overpass, so that it can...
