Crossroads fly-over crossing without red and green lamps

Abstract

The present invention relates to a viaduct bridge for crossroads. It is characterized by that said viaduct bridge has no need of traffic light signal to make traffic control. Said viaduct bridge has two-way straight-going lane bridge floor, on the two-way straight-going lane bridge floor respectively are set at least two lanes, on the outer lanes of two sides of the bridge floor respectively are set forked branch lane for going down from bridge floor and forked branch lane for going up bridge.

Description

technical field [0001] The invention relates to an interconnection design and arrangement of three-dimensional roads, in particular to a viaduct arranged at road intersections without traffic lights. Background technique [0002] With the rapid development of the economy, all kinds of vehicles are also increasing rapidly, which brings huge pressure to urban traffic. Traffic congestion, low efficiency, and frequent accidents have become hot issues in many urban traffic. How to solve the problems existing in urban traffic has become one of the hot spots that the society pays close attention to. For this reason, it is very common to build overpasses and viaducts at crossroads in large and medium-sized cities. Among them, the overpass bridge occupies a large area and engineering quantity, and the cost is high: although the existing viaduct covers an area and the engineering quantity is much smaller than the overpass bridge, and the cost is relatively low, it cannot completely ca...

Among them, the overpass bridge occupies a large area and engineering quantity, and the cost is high: although the existing viaduct covers an area and the engineering quantity is much smaller than the overpass bridge, and the cost is relatively low, it cannot completely cancel the traffic lights, especially the vehicle cannot be solved.
