Unblocked overpass at intersection

Abstract

The invention provides an unblocked overpass at an intersection. The unblocked overpass comprises straight-driving lanes, turning lanes and pedestrian subways, wherein the straight-driving lanes are located at the middle parts of roads, each turning lane comprises a straight-driving section, a right-turn section, a right-turn and straight-driving section, a left-turn and U-turn section and a left-turn and straight-driving section, all the sections are successively connected, the straight-driving section is located at the right side of the part of any straight-driving lane before the intersection, the right-turn and straight-driving section is located at the right side of another straight-driving lane at the driving direction of the right-turn and straight-driving section, the starting end of the left-turn and straight-driving section is positioned between the another straight-driving lane and the straight-driving section of the another straight-driving lane, and guard bars are arranged at two sides of each of the straight-driving lanes and the turning lanes. The unblocked overpass provided by the invention has the following advantages: the overall structure of the overpass is more reasonable and more modularized, the overpass has better adaptive capacity, the situation of cutting-in of vehicles on the overpass is avoided, mobility of vehicles in a city is improved, and traffic jam is avoided.

Description

technical field [0001] The invention relates to the traffic field, in particular to an unimpeded overpass at a crossroad. Background technique [0002] Modern urban traffic often relies on traffic lights to achieve management. Generally speaking, traffic lights play a very good role in helping the orderly form of vehicles at intersections. However, with the acceleration of urbanization, more and more people are flowing into cities. Thereby increased the burden of traffic, traditional traffic lights when running into traffic flow is bigger, help little to the running of using vehicle, the time of traffic lights alternation is not well grasped, still can cause congestion. [0003] The inventor once applied for an invention patent with the patent number ZL200910312299.3 in 2009, in which the background technology also introduced the defects of the existing crossroads, but the patent did not grasp some details enough, and the structure was optimized , the overall design is rela...

[0002] Modern urban traffic often relies on traffic lights to achieve management. Generally speaking, traffic lights play a very good role in helping the orderly form of vehicles at intersections. However, with the acceleration of urbanization, more and more people are flowing into cities. Thereby increasing the traffic burden, the traditional traffic lights are not very helpful to the driving of vehicles when the traffic flow is large, and the timing of the traffic lights is not well grasped, which will still cause congestion

[0003] The inventor once applied for an invention patent with the patent number ZL200910312299.3 in 2009, in which the background technology also introduced the defects of the existing crossroads, but the patent did not grasp some details enough, and the structure was optimized , the overall design is relatively complicated, and it is easy for two vehicles in different directions to appear on the same road at the same time on the viaduct. Sometimes, it is easy to compete with the straight vehicle in the other direction. At this time, the vehicles need to give way to each other, and the part of giving in will cause the vehicles behind the giving vehicle to also stop. Once the traffic flow is large enough, there will be The congestion of the overpass, once the overpass is congested, it will be more troublesome to untangle
