Description

Full three-dimensional urban road system and transportation method using the system

The present invention relates to an urban road system and a transportation method using the system, and in particular, to a three-dimensional urban road system that saves land and a transportation method using the system. It belongs to the field of urban road construction. Background technique

With the improvement of people's living standards, cars have become more and more important means of transportation. However, the increasing number of cars has brought serious traffic problems to urban traffic. The current transportation system is mainly composed of expressways, trunk roads, branch roads, and branch roads (community roads). In order to alleviate traffic jams, it is mainly to establish interchange bridges, increase ring expressways, and add ramps. These methods will occupy a lot of space. Land, for some large cities, the land occupation area of its traffic roads is close to the national regulations. With the development of car family, the improvements made on the existing transportation mode alone cannot meet the serious problems brought by the increasing number of cars. Traffic problems.

Patent No. 93119501. 2, discloses a three-dimensional urban traffic system. The invention clarifies a modern urban road system: all roads form a grid system, preferably orthogonal or non-orthogonal, to distinguish the city In many blocks, or in many communities and factories, all the grid-forming roads are all one-way streets. The basic principle of the same-direction one-way street design is that the forward roads are a retrograde road, alternately arranged, and the cross-directional one-way streets are designed with each other. A single-lane road in a certain direction is all erected by a single-story overpass to form a higher-level interchange system, or it is erected across parts to form undulating waves. All roads are completely closed. A separate roadway can be opened on the side of the road (can be parallel to the elevated road to cross the ground one-level single-way road, or one level can be dug down). It can be used under the elevated single-way road or on the community road. The railway or tram is in principle connected with the ground. One-way streets in the same direction on the first floor are in the same direction and are close together (leave a safety barrier or separate them from the sidewalk) Intersecting single-lane roads are connected by semi-arc overpasses, which are used for vehicle turning, convergence and diversion. Generally, there are three lanes on a single-lane road, one is a left-turn lane, one is a passing lane, and one is a right-turn. Traffic lanes, roads in urban three-dimensional transportation systems, generally do not have signals, and are open at all times. The bus parking station is located on the side of the closed fence, and the fence opens a pedestrian crossing for getting on and off. The bus stops in front of the station. On the road.

This technical solution can save a lot of funds for overpasses, signal systems, and floor space. It is mainly designed based on the single-line principle, and the single-line surround spanning and turning principle. The problem is that it requires more bypass to reach the designated target. It is a waste of time and energy, it is extremely inconvenient to travel, and it is difficult to distinguish roads and occupy a lot of land. Patent No. 9810 ⁷² 7λ 0—A kind of traffic facility with a clear-cut intersection. A separation zone is set up around the post area. The separation zone has motor vehicle entrances and exits along different road directions. The inside of the separation zone is a detour when the vehicle goes straight or turns left. . Outside the barrier are motorways and sidewalks when turning right. Detour on the upper or lower detour of the underground bridge when a bicycle, a person goes straight or turns left. The invention is simple and economical, and reduces the intersection of motor vehicles and bicycles when crossing intersections.

Patent No. 97115611. 5 discloses a method for alleviating traffic congestion. The inner disc and the outer circle are formed by taking the center of the intersection as the center of the circle. Usually, the vehicle can travel around the inner disc. When the vehicle in the saturation boundary is saturated, Vehicles outside the line travel around the outer circle, allowing the vehicle to change its driving direction in the form of a circle, reducing traffic jams and speeding up traffic flow.

Patent No. 98117567. 8 discloses a design scheme of a building and traffic system for a city or a concentrated residential area or a highway. The building and traffic system connects the top of a building together and forms a highway. Underground roads and subways are constructed underground to connect them together, and the two types of roads can be connected to the surface road network or subway network at the same time. This combines the building with the road. In addition, overhead train passages can also be provided on the top side of the building. Compared with the existing building pattern, the invention can fully utilize the above-ground and underground space and save land resources. Its disadvantages are: high cost, poor operability, and the need to reconcile the urban landscape. Summary of the invention

The purpose of the present invention is to provide a three-dimensional urban road system, which uses less floor space, which completely separates motor vehicles from people and non-motor vehicles, improves the utilization rate of roads, and completely solves urban road traffic jams, Difficult parking and traffic zoning issues.

Another object of the present invention is to provide a traffic method using the above system. This method eliminates traffic signal lights in urban road traffic, changes all expressways and trunk roads in the existing urban traffic road classification to expressways, and can realize vehicles. Fast and efficient operation.

In order to achieve the above objective, the technical solution adopted by the present invention is:

A full three-dimensional urban road system, which includes a motor vehicle lane and a non-motor vehicle lane, the transportation system is a layered structure, and the first layer is a ground motor vehicle lane, and a sidewalk or a non-motor vehicle lane is provided on the ground floor of the ground motor vehicle lane; The sidewalk is set up correspondingly to the ground motorway; or the sidewalk is not set up corresponding to the ground motorway, or it is set up at another place on the sidewalk layer that does not correspond to the ground motorway.

Further, the above-mentioned transportation system may also have a sidewalk or a non-motorized vehicle lane above the ground motorized vehicle lane; wherein the sidewalk is provided correspondingly to the ground motorized vehicle lane, and a lateral passage is provided between the sidewalks or non-motorized vehicle lanes provided on both sides; or The ground motorway is not set up correspondingly, or it is set up with the ground machine The moving lanes do not correspond to other places on the sidewalk level.

What is explained here is that sidewalks can be used for walking or non-motorized lanes. Alternatively, the sidewalk is divided into walking paths and non-motorized lanes.

Motorways include expressways and branch roads. Separate overpasses are set at the intersections of expressways. The overpasses use branch roads to complete the function of ramps.

-Or set the sidewalk above part of the branch road as a circular passage or an overhead square. Alternatively, a ring road is provided at the intersection of the branch road, and the ring road may be a single line in the counterclockwise direction when passing on the right side.

In addition, all of the ground motor vehicle lanes can be set as expressways, and separate overpasses can be set at the intersections of the expressways.

At least one U-turn road is provided between the intersections of the two expressways or a U-turn road is provided under the separate overpass; it is preferable to set one U-turn road between the two intersections of the expressway.

Between each two parallel expressways, a ramp for the expressway and a passage to the community road may be provided.

The first floor of the buildings on both sides of the road is used for parking, greening and driving-related facilities. It can also be used as an overhead layer for vehicles to detour in emergency situations; the sidewalk layer located on the upper part of the motorway is directly adjacent to it. The upper floor is connected or disconnected.

U-turn roads are set at city boundaries and near the T-junctions in some sections of the city; or, a dedicated ramp is provided to solve the problem of left-turns; or, left-turn separate overpasses are alternately set up at the T-junctions of expressways; or, Set T-junctions on a single branch road.

In addition, the above-mentioned ground motorway may be partly set as an elevated road or an underpass; the sidewalk may be partly set up where the ground floor does not conflict with the motorway.

The invention also relates to a traffic method using the above-mentioned three-dimensional urban road system, wherein the motor vehicle lane includes an expressway and a branch road, the expressway is provided with a separate overpass at the intersection, the expressway is straight and turns along the driving direction to the passing side , Use the branch road to complete the function of the ramp; or, the branch road is only allowed to go straight or turn in the driving direction to the passing side. In this way, no semaphore lights are set at the expressway intersection, people and vehicles are separated, and the speed of passing is greatly improved. Although some roads need to be bypassed in this way, the travel time will be greatly reduced due to the smoothness of the overall road.

The above expressway is going straight or turning in the direction of travel, which means that for countries or regions designated as left-hand traffic, you can only turn left in the direction of travel; while in countries or regions designated as right-hand traffic, follow The direction can only turn right.

Intersections of branch roads and branch roads can only allow right turns or be managed in a conventional manner.

Due to the adoption of the above technical solution, all the main roads are changed to expressways, the density of expressways is increased, and traditional ramps are cancelled. The branch roads are used to complete the functions of the ramps, and at the same time, the opposite side turn to the road passing side is cancelled. Interchanges no longer appear on the road. As a result of this design, people and cars are completely separated, On the one hand, a large amount of road area is saved, and on the other hand, all interchanges of motorway intersections or collision-free traffic are realized, forming a criss-crossing collision-free traffic system throughout the city.

The invention is described in detail below with reference to the drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

The full three-dimensional urban road system of the present invention includes a motor vehicle lane 1 and a non-motor vehicle lane 2, the transportation system is a layered structure, and the first floor is a ground motor lane 1, and a sidewalk is provided on the ground floor of the ground motor lane 1 Or a non-motorized lane; where a sidewalk is set up corresponding to a ground motorized lane; or a sidewalk is not set up corresponding to a ground motorized lane, or it is located elsewhere on the sidewalk layer that does not correspond to a ground motorized lane (not shown in the figure).

In addition, a sidewalk 1 or a non-motorized lane 2 may also be provided above the ground motorized lane; see FIG. 1 and FIG. 2, the full three-dimensional urban road system of the present invention, the sidewalk also functions as a non-motorized lane, the traffic The motorway 1 on the first level of the system is set on the ground of the city, and a layer of sidewalk 2 is provided at an appropriate height above the motorway. Departments set sidewalk layers 3 and 4 of appropriate width respectively, and can also set up two structures at the same time in the same city's transportation system.

When a first sidewalk layer 3 and a second sidewalk layer 4 are respectively provided on the upper sides of both sides of the motorway 1, a lateral passage 5 is provided between the sidewalks 3 and 4 on both sides (see FIG. 3). A guardrail 14 is provided on at least one side of the sidewalk layer 3 or 4. Ring roads or overhead squares are set up on the sidewalks at some intersections of the branch roads.

Alternatively, when the first sidewalk 3 and the second sidewalk 4 are not set corresponding to the ground motorway 1, it may be The sidewalk 2 is installed elsewhere on the sidewalk layer that does not correspond to the ground lane (the structure shown in the figure is omitted). Motorway 1 includes expressway 6 and branch roads 7, each branch road 7 is located between every two express roads 6 and is used as a ramp and access road to express road 6 (community road, in the figure) (Not shown).

Separate overpass 9 is set at the intersection 8 of expressway 6 and expressway 6, and motorway 1 uses branch road 7 to complete the function of the overpass ramp. The distance between the branch road 7 and the expressway 6 is preferably L / 2 to reduce land occupation. Branch roads also serve as ramps for expressways.

Referring to FIG. 4, at least one U-turn road 10 may be provided on the expressway 6 between two or more intersections. The number of U-turn roads 10 can also be set according to the length of the road between intersections and the actual needs to reduce the detour distance. In addition, there are 9 separate overpasses at 8 intersections, and U-turn roads (not shown in the figure) can also be set under the overpass 9.

The first floor of the building 19 on both sides of the road 6 or 7 is an overhead layer 11, and an overhead layer 11 is formed between the ground and the first floor slab 12. The overhead layer 11 of the building can be used for parking, greening and driving-related facilities construction. Can be used for vehicle detours in emergency situations. When the sidewalk layer 3 or 4 is close to the building, the sidewalk layer 3 or 4 is directly connected with the floor slab 12 on the upper part of the overhead layer 11, which not only facilitates pedestrian travel, but also saves the side fence.

The first floor of the city's buildings can also be all overhead floors, which are used for parking, greening, improving urban ventilation, and alleviating the urban heat island phenomenon.

T-junctions will appear at the boundaries of the city and in some parts of the city, such as tracks and rivers. U-turn roads 99 (Figure 5) are located near the T-junctions to solve the problem of left turns; or, Dedicated ramps to solve the problem of left turns; or, separate left-turn separate overpasses 15 (see Figure 6) at T-junctions on expressways; or set T-junctions on branch roads to avoid T-junctions on expressways. The branch road is single line to complete the function of the expressway ramp (see upper part of Figure 1).

Referring to FIG. 7, it is also possible to set all ground motorway 1 as expressway 6 and set up a separate overpass 9 at the intersection 8 of expressway 6 and expressway 6.

Generally, the vertical and horizontal directions of the branch road 7 are orthogonal (see FIG. 1), or a ring road 71 (see FIG. 8) is added at the intersection, and the ring road 71 passes on the right side. Can be a single line counterclockwise.

The traffic method of the three-dimensional urban road system is as follows: Refer to Figs. 1 and 4. If a motor vehicle starts from point A to reach point B, since all expressways 6 do not have a left turn, motor vehicles can be at the intersection of expressway 6. 81, that is, turn right at point E, via the EL line of expressway 6, turn right at branch 16 (L) to branch road 7, to the intersection of expressway 6 and branch road 7 (at N) , Turn right at intersection 17, follow expressway 6 straight to intersection 83 (0) at expressway 6, then turn right again, and finally go straight to point B, Each route is denoted as AC- DELM- N-0-PB. With this route, the LM-N on the branch road 7 functions as a ramp. Or follow the A-C-DMN-0-B route to point B. Other feasible routes include but are not limited to AC-DEFK-LEP-B, A-CDE-F-G-HIJQ-B, etc. At this time, the corresponding part on the branch road 7 functions as a ramp. As shown in FIG. 4, the motor vehicle may also make a U-turn '10 U-turn between FG of Expressway 6, turn right at points E and P, and then go straight to point B. There is no need to set traffic dispatch lights on expressways, and the speed of vehicles is greatly increased.

If the motor vehicle starts from point A and wants to reach point τ opposite point B, in addition to the above driving route, it only needs to make a U-turn at the U-turn lane 10 set at X shown in Fig. 4 or a U-turn at an overpass 9 Turn around and go straight to point Z. Any two points between other urban roads can follow the above method.

For countries on the left, just change the right turn to all left turns.

With the above-mentioned transportation system, under the premise of urban group planning, it simultaneously solves the problems of traffic jams, parking difficulties, and channelization of traffic, which can shorten travel time and prevent the quality of traffic from being affected by the expansion of the city.

According to a preliminary estimation, the system and method of the present invention can increase the car capacity of the city by 3 to 4 times and reduce the travel time to the same distance by 1 time on the premise of the existing road area. Road investment was doubled, and traffic management operating costs were reduced to one-third the usual.

The system and method of the present invention can be used for the construction of a new city, and can also be used as a target mode for road reconstruction in an old city. In the reconstruction of the old city, it is possible to build a new area adjacent to the old area in accordance with this patent, and gradually reduce the traffic volume in the old city area, and then gradually rebuild the roads in the old area according to the speed of the buildings.
