Crossroad tunnel system and running method thereof

Abstract

The invention discloses a crossroad tunnel system which comprises an over-ground layer and a tunnel layer under the over-ground layer. Compared with the prior art, the system is characterized in that firstly, the east section and the west section of the tunnel layer do not need to be independently provided with U-turn lanes, so that the east-west length of a whole crossroad tunnel is small, land is saved, construction difficulty can be reduced, and therefore cost is lowered; secondly, outer lanes are adopted to the U-turn lanes of all the sections and are of a U shape, and therefore the turning radius of the U-turn lanes is increased, and turning of large passenger cars and the like is facilitated; thirdly, two inclined lanes are arranged from the over-ground layer into the tunnel layer at the east section and the west section, accidents or traffic jam caused when cars fight for entering the inclined lanes can be avoided, and when accidents happen in the inclined lanes, trailers can enter the tunnel conveniently for rescue. Accordingly, problems in the prior art are solved, running cars can run smoothly, traffic lights are not needed, and traffic jam at a crossroad can be effectively relieved.

Description

technical field [0001] The invention relates to the technical field of traffic, in particular to a crossroad tunnel system and a driving method thereof. Background technique [0002] With the development of society and economy, the number of domestic cars is increasing, and traffic jams are becoming more and more serious. People spend more and more time on the road. Car traffic speed, the general practice is to build various viaducts and overpasses at crossroads, or set up traffic lights, so that the vehicles that go straight, turn left, turn right and turn around can be diverted. At intersections with a large traffic flow, if traffic lights are not used, the overpasses to be built are often extremely complicated, and the vehicle detour method is also very complicated, causing many drivers to get lost as soon as they get on the overpass, and do not know how to get off; if traffic lights are set up, because Vehicles need to wait and stay, and intersections become congestion ...

AI Technical Summary

Problems solved by technology

For example: the Chinese patent No. 201110234955.X that the applicant previously applied for is an invention patent, which discloses a crossroad tunnel system and a method for using the system. Vehicles can move unimpeded without traffic lights, effectively alleviating traffic jams at crossroads; however, the shortcomings of this crossroad tunnel system are: 1. The east and west sections of the tunnel layer need to set up U-turn lanes separately, resulting in the entire crossroad tunnel 2. The two inner lanes of each section of the tunnel layer are U-turn lanes, resulting in a smaller turning radius of the U-turn lane, which is not conducive to large passenger cars and other U-turns; 3. In the east and west sections, enter from the ground floor In the tunnel layer, there is only one ramp, which can easily lead to accidents or traffic jams between vehicles of two lanes scrambling to enter the ramp, or when an accident occurs in the ramp (for example: a vehicle breaks down in the ramp and breaks down), it will cause a big traffic jam , and it is not convenient for trailers etc. to enter the rescue
