Two-layer overpass with traffic light

Abstract

The invention discloses an overpass and a two-layer overpass with a traffic light. Traffic light control and a two-layer overpass are organically combined at a crossroad; straight lanes, u-turn lanesand left curves in four directions of the crossroad are selectively divided into a ground layer and a bridge deck layer; there are only two straight lanes, two u-turn lanes and two left curves in a crossing in each layer; and one straight lane, one u-turn lanes and one left curve share an exit lane in one direction; and therefore, the crossing in each layer only has two exit lanes; the crossing ineach layer has one set of traffic light control system; one traffic light period only needs one straight phase and one left turning phase to take turns; the area of the crossing in each layer is reduced; and the vehicle parking position moves forwards. The two-layer overpass with the traffic light is an overpass with the lowest layer and has the advantages of small floor space and low construction cost; an existing crossroad is easy to remodel; and the traffic congestion problem of the crossroad can be effectively solved.

Description

technical field [0001] The invention relates to an overpass, more specifically, the invention relates to a two-story overpass with a traffic light control system. Background technique [0002] At present, the traffic of vehicles and pedestrians at urban crossroads is generally controlled by signal lights or overpasses, but the effects are not very satisfactory. Crossroads are the bottleneck of the entire urban traffic. Using the control method of signal lights alone, the traffic capacity of crossroads is limited, resulting in long waiting times for vehicles and often causing urban road congestion. Although the way of overpass bridges can solve the traffic problem, most of the overpass bridges in China are three-story structures, and some even have four-story structures, which occupy a large amount of urban land, and the cost is also high, which affects the urban landscape. The two-story overpass with traffic lights proposed by the present invention has only one two-story br...
