Overpass for city

Abstract

The present invention provides a three-layered overpass including one main path, one main bridge, four left turn lanes, four right turn lanes, four straight non-motored vehicle lanes, and four turn-back lanes. The four left turn lanes are joined into the separate straight lanes smoothly to complete direct left turn. The overpass has separate lanes in different directions without conflict and interweaving. It has very small covered area and low building cost, has only single lane and no complicated road mark, and has separate lanes for motor vehicles and non-motor vehicles. With turn back lanes in different directions can solve traffic jamming.

Description

Technical field: [0001] The invention relates to the field of transportation, in particular to a new type of urban highway overpass with novel and unique design, ingenious conception and connection with nature. Background technique: [0002] In view of the fact that in recent years, with the development of the automobile industry and the continuous improvement of people's living standards, automobiles have become an indispensable means of transportation for people to travel. Due to the rapid increase in the number of automobiles, urban traffic has brought great pressure, and traffic lights in cities have passed Many, narrow traffic roads, so the phenomenon of traffic jams is becoming more and more serious. Especially during morning and evening peak hours, urban traffic is in a state of paralysis, and crawling cars are everywhere in the streets and alleys, forming a creeping group that cannot be seen from head to tail. One of the main reasons is that there are no overpasses ...

Problems solved by technology

One of the main reasons is that there are no overpasses at many crossroads, and they are all controlled by traffic lights. However, the existing overpasses are generally backward in design and unreasonable in structure. The problem is that the left-turning vehicle detours a long way and intersects with one side of the straight-going vehicle to form an intersection point, which prevents the vehicles behind from driving. Because the turning vehicle interferes too much with the main line vehicles, the car cannot pass smoothly, and time and energy are wasted here. How many important things are delayed, coupled with the intermingling of motor vehicles and non-motor vehicles, resulting in chaotic situations and even traffic jams

ZL92105467 discloses a directional overpass, which is divided into five bridges and three bridges. Its advantage is that it occupies a small area and overcomes the shortcoming of turning left and going round the roundabout. The sharp left turn and the intersection with the right turn lane in the opposite direction have great interference, which makes the traffic not smooth, the speed is slow, and the driving safety is poor. In addition, due to the complex structure and the separation zone in the center, the construction investment is large

Application number is that the patent of 00105270.5 discloses a kind of high-speed direct steering type overpass, and its advantage is that the traffic in each direction is smooth in one way, and realizes the direct and fast left turning, but the floor area is large, the cost is high, and it does not solve the problem of motor vehicles and non-motor vehicles. The problem of separate driving of motor vehicles
