Interchange Crossroad with People Walking on Ground, Vehicles Traveling Above and Under Ground, and Only Vehicles on the Same Way Giving Way to One Another

Abstract

An interchange crossroad with people walking on ground and vehicles traveling above and under the ground is provided. In a basic type, four layers are comprised which are an overpass, a mezzanine, a ground plane and an underpass from up to down, the overpass and underpass respectively allow vehicles traveling longitudinally and vehicles traveling transversely to go straight and make a turn, only vehicles on the same road give way to one another under traffic lights, and the overpass and underpass are provided with lateral parking horizontal wing spans of adjustable lengths. In a reduced and flexible type, the four layers are reduced to three layers, only vehicles giving way to one another is achieved, all the vehicles are centralized on either the overpass or the underpass and commanded by traffic lights. The entire crossroad zone of the ground plane layer has no vehicle and is used exclusively for citizens.

DETAILED DESCRIPTION OF EMBODIMENTS

[0057] It is not limited to a typical orthogonal crossroad, and oblique crossing, multi-road crossing or the like may be included, which can be implemented flexibly.

[0058] Vehicles, pedestrians and bicycles are isolated from one another by a layered structure. The overpass layer of the basic type allows only vehicles traveling in a longitudinal direction to pass through, and allows only vehicles going straight and vehicles making a turn to give way to one another. Thus, the time of waiting for a red traffic light is greatly shortened, and the crossroad is unobstructed. For the same reason, the underpass layer of basic type allows only vehicles traveling in a transverse direction to pass through, and allows only vehicles going straight and vehicles making a turn to give way to one another. Thus, the time of waiting for a red traffic light is greatly shortened, and the crossroad is unobstructed.

[0059] Traffic rules are very simple and conventional, and are familiar to drivers. Moreover, the time of waiting for traffic lights is greatly shortened, and the cost and maintenance fees of the traffic lights are also greatly reduced.

[0060] Below, a specific technical construction of an interchange crossroad with people walking on the ground, vehicles traveling above and under the ground and only the vehicles on the same road giving way to one another, and a method of passing therethrough, which are provided by embodiments of the present invention, will be explained extendedly.

[0061] The technology that only the vehicles on the same road give way to one another in the present invention is used in combination with a technology of turning right, driving horizontally and making a U-turn. That is, a certain road adopts the technology that only the vehicles on the same road give way to one another, while another road intersecting with this road adopts the technology of turning right, driving horizontally and making a U-turn. In this case, the another road has no red traffic light, needs not to wait, and is completely unblocked; and the certain road adopting the technology that only the vehicles on the same road give way to one another is unblocked.

[0062] The so-called technology of turning right, driving horizontally and making a U-turn means that, the lateral horizontal wing span is lengthened, and a vehicle which wants to turn left does not turn left directly on the crossroad, but turns right first, travels horizontally, and makes a U-turn at the end of the wing to adjust to the right direction, and then goes downhill or uphill back to the ground to join the traffic flow on the main ramp of the overpass or underpass, passes through the crossroad and then returns to the ground, and travels out of the crossroad.

[0063] Whether or not to use the technology of turning right, driving horizontally and making a U-turn depends on the conditions and development intentions of various cases.

[0064] According to the interchange crossroad and the method of passing therethrough provided by the embodiment of the present invention, there is no need to use a cloverleaf-shaped road to carry out turning and diverging of vehicles, and the urban land can be greatly saved under the same traffic capacity. According to the interchange crossroad and the method of passing therethrough provided by the embodiment of the present invention, the rules based on which vehicles turn left and turn right are simple and can be easily grasped by drivers, and meanwhile, it is safer for the vehicles, and the traffic is more smooth. Moreover, the amount of engineering is relatively small, which facilitates the widespread use thereof.
