Description

Three-dimensional, ground, and circular intersection traffic lanes

technical field

The invention relates to a traffic lane at a three-dimensional, ground and circular intersection, which belongs to the field of urban public traffic road construction.

Background technique

In cities, various forms of overpasses are currently used to solve the traffic jam problem at intersections, but they have the following disadvantages: 1. There are many intersections; 2. The detour route is long/3, and multiple lanes are mixed on the bridge , often cause traffic accidents due to the rushing of the driver, especially the rushing of the car; 4, the cost is also high. The reason is that the designers neglected the coordinated construction of the overpass, the ground, and the circular lane, and underestimated the huge multi-channel diversion effect of the ground and the circular lane; Faster, fewer accidents, and low construction costs, but too much emphasis has been placed on the construction of multi-lane roads with mixed traffic of multi-grade vehicles, which increases the chance of accidents and increases construction costs.

Contents of the invention

The object of the present invention is to provide a three-dimensional, ground and circular intersection traffic lane with fast vehicle speed, safe driving, less detours and many driving routes for drivers to choose.

The present invention is characterized in that it contains left, straight and right single-lane overpasses that separate forward and reverse, mutually orthogonal single lanes that separate forward and reverse on the ground, double lanes on the left and right on the ground, and both forward and right on the ground. The straight-through single-lane that separates from the reverse direction connects and connects with the central circular lane that communicates with the left and right dual-lane on the ground via the radial two-way lane. The left and right double lanes on the ground are one-way driving.

The left and right double lanes on the ground are two-way driving. The left, straight, and right single-lane overpasses separated along the ground and reversed, the straight single lanes separated by the retrograde, the double lanes left and right on the ground, and the central circular lane all communicate with a peripheral large circular lane. The forward and reverse traffic bridges of the left or right single-lane overpass are respectively higher than the straight single-lane overpass. The forward and reverse traffic bridges of the left or right single-lane overpass are respectively lower than the straight single-lane overpass. The central roundabout where the central circular lane is located is provided with left and right lanes that are separated from forward and reverse traffic and run through the central roundabout. The central circular lane is sequentially provided with non-motorized lanes, motorized lanes and small lanes from outside to inside. The left and right double lanes on the ground are left and right single lanes on the ground.

In order to describe the present invention in detail below in conjunction with embodiment, now the accompanying drawing name and the numbering brief introduction that this application document uses are as follows:

Description of drawings

Figure 1: Plane design of traffic lanes at intersections in Yuquanying, Beijing, where three-dimensional, ground, and circular traffic interact.

Detailed ways

Example:

Please see Figure 1. Yuquanying Roundabout, with a diameter of 400 meters, is the only flat roundabout on Beijing's Third Ring Road, the South Gate of Beijing, and the starting point of National Highway 106. It was completed in 1989. According to reports, in 1996, there were 80,000 motor vehicles passing through daily, and the traffic jam was the most in Beijing. Every day, 6-8 traffic policemen were required to work overtime in the morning and evening to clear the traffic, so as to solve the disputes between non-motor vehicles, motor vehicles, heavy-duty vehicles and small vehicles. However, traffic accidents such as scraping and overtaking still occur frequently. Even building an overpass bridge with the highest performance in China still cannot solve the problems of low vehicle speed, many detours and crossing of motor vehicles and bicycles when turning left.

Please refer to Fig. 1 for the technical scheme proposed by the present invention. It contains left, straight and right single-lane overpasses 1, 2 and 3 separated along and reversed, mutually orthogonal single-lane 4 separated along the ground and reversed, double-lane 5 left and right on the ground and both parallel to the ground , the straight-through single lane 4 of retrograde separation is connected and the central circular lane 7 that is communicated with the left and right dual lanes 5 on the ground through the radial two-way lane 6. According to the specific situation of the Yuquanying roundabout, it has the following characteristics: 1. The outer large ring road 8 is the original one, and there is no need to set up another; 2. The left and right overpasses 1 and 3 that are separated from the forward and reverse directions are only set in the central roundabout. The south end, and the left and right overpasses 1 and 3 going forward are the lowest positions in each overpass in space so as to reduce the cost, and the left and right overpasses 1 and 3 of the retrograde are the highest, which are higher than the straight overpasses 2 separated by the forward and retrograde. It is also conducive to reducing the cost. These overpasses all are single-lane so that speed-up is suitable for trolley to pass through. 3. The left and right dual lanes 5 on the ground are only set at the northern end of the central roundabout to make up for the lack of left and right overpasses 1 and 3; while at the southern end of the central roundabout, only forward left and right single lanes 10 are provided. , its retrograde lane can be replaced by left and right retrograde overpasses 1,3 to reduce the cost. The ground left and right double lanes 5 can be unidirectional or bi-directional, and in this example, the left is forward and the left is reversed. 4. At the northern end of the central roundabout, a one-way lane crossing through the central roundabout to the left and reverse to the right is built on the ground to make up for the lack of left and right overpasses 1 and 3 at the northern end of the central roundabout and the ground only has the right Insufficiency of double lanes with forward traffic and reverse traffic on the left. 5. On the central roundabout, non-motorized lanes, motorized lanes and small lanes are divided from inside to outside to avoid overtaking and grabbing the road, and all of them are connected with the single lane 4, which is perpendicular to each other on the ground, so as to facilitate heavy-duty vehicles on the bridge. Go north-south and east-west. 6. The radial two-way driving lane 6 of the central roundabout communicates with the left and right dual lanes 5 on the ground, so as to facilitate access to various public transport stations in the big roundabout, and can also be used as a diagonal lane between north and south and east and west.

Thus it can be seen that the present invention has the following advantages: 1. Three-dimensional, ground and circular lanes intersect, which is convenient for the diversion of non-motor vehicles, motor vehicles, heavy-duty vehicles and dollies; Single lanes account for the vast majority, and even double lanes run in the same direction, which is conducive to increasing the speed of vehicles, and also prevents the occurrence of traffic accidents caused by overtaking on the road; , Reversed separation, no crossing between each other, avoiding detours, and less running; 4, The design scheme of the ground lanes is connected by circular, orthogonal, and oblique lanes, which can neither detour nor separate traffic and separate lanes for bicycles , which is conducive to increasing the speed of vehicles, and is also conducive to connecting with various bus stations all over the Dahuan Island, which is convenient for pedestrians to travel and transfer.

In a word, the present invention achieves less crossings, less detours, faster vehicle speed, more driving lanes to choose from, and low cost.
