Non-cross connection point of crossroad of Chinese knot road

Abstract

The invention discloses a non-cross connection point of crossroad of Chinese knot road. The connection point comprises a longitudinal road and a horizontal road, which are respectively equipped with motor vehicle lanes and non-motor vehicle lanes; the longitudinal road spans the horizontal road through a motor vehicle viaduct and two non-motor vehicle viaducts located at two sides of the motor vehicle viaduct; four right-turn bridges which stretch towards right corresponding to the straight vehicles are set up between the longitudinal motor vehicle lanes and the horizontal motor vehicle lanes; circular left-turn curved bridges which are respectively connected with four right-turn bridges are set up above the motor vehicle viaduct; four left-turn lanes which are connected with the horizontal non-motor vehicle lanes and does not affect the straight vehicles are arranged on the longitudinal non-motor vehicle lanes; four right-turn lanes which stretch towards right corresponding to the straight vehicles are set up between the longitudinal non-motor vehicle lanes and the horizontal non-motor vehicle lanes. The road structure provided by the invention can separate the motor vehicles from the non-motor vehicles synchronously without traffic light, thus, the non-cross connection point improves driving efficiency and safety, and overcomes many problems of the synchronous bypass road structure in prior art.

Description

technical field [0001] The invention relates to a road structure at a crossroad. Background technique [0002] At present, most of the traffic flow at intersections is realized through traffic lights. With the improvement of people's living standards, the number of vehicles is increasing, which brings traffic pressure to intersections. It is often necessary to wait for a long time at intersections during the peak period of vehicles. , brings inconvenience to people's travel, and because individual drivers have poor reaction, judgment ability and traffic awareness, they often run through red lights, which poses serious safety hazards. To solve the above problems, the invention patent No. 201110443530.X provides A continuous highway overpass structure is proposed. By setting the turning ramp, the vehicles with different steering directions will not interfere with each other, so that there will be no traffic lights at the intersection, the vehicles will be unimpeded, the road u...

[0002] At present, most of the traffic flow at intersections is realized through traffic lights. With the improvement of people's living standards, the number of vehicles is increasing, which brings traffic pressure to intersections. It is often necessary to wait for a long time at intersections during the peak period of vehicles. , brings inconvenience to people's travel, and because individual drivers have poor reaction, judgment ability and traffic awareness, they often run through red lights, which poses serious safety hazards. To solve the above problems, the invention patent No. 201110443530.X provides A continuous highway overpass structure is proposed. By setting the turning ramp, the vehicles with different steering directions will not interfere with each other, so that there will be no traffic lights at the intersection, the vehicles will be unimpeded, the road utilization rate will be improved, and the driving will be convenient and safe. Motor vehicle lanes and non-motor vehicle lanes are technically difficult and costly, and motor vehicles and non-motor vehicle shared lanes will inevitably interfere with each other, posing safety hazards. Therefore, it is impossible to realize the synchronous diversion of motor vehicles and non-motor vehicles

[0003] The invention patent with the patent number 201220481218.X provides a synchronous diversion intersection and T-shaped intersection road structure, which solves the above technical problems and realizes the synchronous diversion of motor vehicles and non-motor vehicles without traffic lights at intersections. The scheme realizes the left turn of the motor vehicle through the left turn bridge of the motor vehicle, and realizes the left turn and right turn of the non-motor vehicle through the circular lane of the non-motor vehicle, but due to the setting of the left-turn bridge, the non-motor vehicle lane of the transverse road must be lower than Motor vehicle lanes, which are easy to cause non-motor vehicle lanes to accumulate water in the rainy season, which is not conducive to the driving of non-motor vehicles; due to the small turning radius of the left-turn bridge, long and large vehicles cannot pass; the driving direction of the circular lane is clockwise , while the driving direction of the conventional round-the-island lane is counterclockwise, it is easy for the driver to make a mistake in judging the driving direction, causing the driver to drive in the opposite direction, and there are potential safety hazards
