Abstract

The invention discloses a herringbone type full-pass crossroad with few lane changes, which avoids line intersection caused by left-turn of vehicles by replacing left-turn in a turning mode of turning around and turning right. Compared with the mode that the vehicle turns right and then turns around to replace left turning, the vehicle does not need to change lanes after turning around and then turning right, and the passing efficiency is higher. According to the theory, the herringbone type small lane changing full-pass crossroad is designed and optimized for multiple times.

Description

Herringbone type less lane changing all-pass crossroad

Technical Field

The invention relates to the technical field of traffic road structures, in particular to a herringbone type full-traffic crossroad with few lane changes.

Background

With the rapid development of the urbanization process, the problem of urban road congestion always puzzles people, and congestion causes a large amount of gasoline resource waste and consumes a large amount of time cost. The common mode at present is traffic lights, and the mode of large-scale overpasses and roundabouts relieves road congestion. Due to the traffic light mode requiring vehicles to wait, a lot of congestion and even traffic paralysis can occur during rush hour. The large overpass needs to occupy a large amount of land, has high manufacturing cost, is easy to miss, and the like, and is rarely used for urban roads with small soil and small gold. The roundabout road also needs to occupy a large amount of land and the automobiles need to exit the roundabout through lane changing in the roundabout, so that traffic paralysis is caused because congested vehicles cannot exit through lane changing when the traffic flow is overlarge. There is therefore a need for a new design that addresses the above problems.

Disclosure of Invention

The invention aims to solve the problems that traffic lights need to wait, a large overpass occupies a large area and has high cost, and vehicles on a roundabout road need to change lanes frequently and the like. A herringbone small-lane-changing all-pass crossroad is provided.

In order to solve the problems, the technical scheme provided by the invention is as follows: a herringbone type small lane changing full-pass crossroad. As shown in figure 1, the herringbone type lane-changing all-pass intersection consists of main lanes (1 to 24 lanes) in the east-west-south direction, right-turn lanes (25 to 28 channels), left-turn channels (29 to 32 channels); an arch bridge deck. The

main lanes

5, 11, 17 and 23 are left-turn or U-turn lanes;

lanes

6, 12, 18 and 24 are straight or right-turn lanes; the arched bridge deck is positioned at the intersection of the south-north road surface and the east-west road surface, a channel is reserved for opening design at the middle position of the intersection of the arched bridge deck and the road surface, and vehicles in 4 lanes and 16 lanes can pass through the arched bridge deck; the lane 29 of the left turn passes through the arched bridge from the lane 16 to be connected with the lane 19, the lane 30 is connected with the arched bridge deck by the lane 1 and the lane 22 by the arc-shaped slope, the lane 31 passes through the arched bridge from the lane 4 to be connected with the lane 7, and the lane 32 is connected with the arched bridge deck by the arc-shaped slope 10 and the lane 13;

the vehicle is driven straight: the vehicle travels from a straight or right-turn lane. Taking a 6-lane vehicle as an example, the vehicle enters a 6-lane vehicle and travels forwards to enter a 13-lane vehicle to finish straight traveling; the same principle is applied to 12-lane, 18-lane and 24-lane vehicles.

And (3) turning the vehicle right: the vehicle travels from a straight or right-turn lane. Taking a 6-lane vehicle as an example, the vehicle enters 26 lanes from the 6 lanes and then enters 7 lanes to complete right turn; the same principle is applied to 12-lane, 18-lane and 24-lane vehicles.

Turning left of the vehicle: the left turn is replaced by the right turn after turning around. The vehicle travels from a left turn or a turn around lane. The 5-lane vehicle goes straight into the 15 lanes through the arch bridge, turns around and enters the 16 lanes, then passes through the arch bridge and enters the 19 lanes through the right-turn lane 29 to complete left turn, and the 17-lane vehicle is similar to the vehicle. The vehicle with 11 lanes goes straight into 21 lanes, turns around and then enters 22 lanes, and then enters 1 lane through the right-turn lane 30 to complete left turn, and the vehicle with 23 lanes similarly.

Turning the vehicle around: the vehicle runs from a left-turn or turning lane, taking a 5-lane vehicle as an example, the vehicle enters a 15 lane from the 5 lane through an arch bridge, enters a 16 lane after turning around, and enters an 18 lane through lane changing to complete turning around. The same applies to 11-lane, 17-lane and 23-lane vehicles.

The invention has the following advantages: 1. traffic lights do not need to be arranged at the crossroad, so that the time for waiting the traffic lights is saved, and the passing efficiency is improved; 2. the invention can finish straight running, left-turning and right-turning running under the condition of not changing lanes. The vehicles turn around or enter the next crossroad to change the driving lane according to the actual requirement, and then the lane change in the same direction is needed. In one complete driving, most of the operations of straight running, left turning and right turning are carried out, the turning operation is less needed, even if the turning operation is needed or the lane change operation is needed, the lane change in the same direction has slight influence on the normally running vehicle, and the passing speed is hardly influenced; 3. the invention has simple design and convenient construction, the construction cost and the occupied land area are far smaller than those of a large-scale overpass, and the invention is suitable for the construction of urban roads and other roads. 4. The road redundancy is large, the condition of road congestion and paralysis can not occur under the condition that the traffic flow is increased rapidly on the commute or holiday, and the traffic police are not required to command and dredge the traffic on site. When the traffic flow is large, the traditional traffic light intersection can cause traffic paralysis because the jammed vehicles cannot move forward or cannot move backward when driving to the middle of the road, and when the other lanes have green lights, the middle lanes of the intersection cannot pass through because the vehicles occupy the middle lanes of the intersection. If the vehicles are blocked in the roundabout road, the vehicles cannot drive out of the roundabout to cause traffic paralysis, and the traffic can be dredged only by manually dredging the vehicles by traffic police on site in the two conditions. Even if the intersection is blocked due to the congestion of the road in front, vehicles do not need to cross run, running routes in all directions are independent, and the running of the vehicles in other directions cannot be influenced under the condition that one intersection is blocked. After the congested road is dredged, the vehicles blocked at the intersection can automatically drive away from the intersection, the condition that the road is knotted and paralyzed can not occur, and the traffic police can not command and dredge the traffic on site. 5. The expansibility is strong, and independent straight lanes such as a left-turn or turning lane and a right-turn or straight lane can be added according to actual needs to improve the traffic efficiency of the crossroad.
