A twist-shaped road network system with trunks mixed with right-hand and left-hand driving

Abstract

The invention discloses a twist-shaped road network system with trunks arranged in a mixed arrangement of driving on the right and on the left. A group of driving plane functional layers that are distributed in any order along the vertical space direction and are mutually forward and reverse driving directions. The driving plane functional layers include multiple intersecting two-way driving lanes, and the intersection of the two-way driving lanes is a road that only allows left turns or The intersection of right-turning roads and straight-going roads without conflict points, and the straight-going roads of two adjacent intersections in the same driving plane functional layer are in a cross distribution; the corresponding matching straight-going roads between two adjacent driving plane functional layers There is a jump lane corresponding to the driving direction between the lanes in the same direction between the roads. The invention allows the vehicle to run at high speed in the whole process without waiting for traffic lights, and allows the vehicle to go straight at a busy intersection and directly turn left and right without building an overpass.

Description

technical field [0001] The invention relates to a road network system, in particular to a twist-shaped road network system with trunks arranged in a mixed manner for driving on the right and on the left. Background technique [0002] With the development of the automobile industry and the increase of automobile penetration rate, urban road traffic congestion is becoming more and more serious. Even in cities that are not congested, the average speed of driving is also low. After analysis, the main causes of urban traffic congestion are as follows: [0003] 1. In a certain area of ​​the city, the road area ratio is constant, the population and the number of cars in the area continue to increase, and the urban road area per vehicle continues to decrease. When the number of cars owned exceeds the carrying capacity of the road, the urban road area per vehicle becomes smaller. The more traffic jams. [0004] 2. In today's cities, traffic lights are an effective way to maintain t...

Problems solved by technology

In addition, the traffic light intersection rate is low

[0005] 3. Existing urban overpasses have greatly improved the traffic speed and efficiency of vehicles. The construction of overpasses requires a certain amount of space, but there are many buildings in the bustling areas of the city. The closer to the roads and intersections, the taller and denser the buildings , which greatly limits the construction of overpasses, so many intersections in bustling cities cannot use overpasses to alleviate traffic congestion.

In addition, the large overpass bridges that have been built still show congestion, because the overpass bridges have not fundamentally effectively increased the average road area per vehicle
