Rotary intersection traffic structure

Abstract

The invention relates to the technical field of road intersection design and provides a rotary intersection traffic structure. The rotary intersection traffic structure comprises four main roads whichare correspondingly positioned in four different directions; each main road comprises an entrance lane for vehicles to run in and an exit lane for the vehicles to leave away; the entrance lane of anymain road is provided with a corresponding first right turning passage; the entrance lanes of the main roads communicate with the exit lanes of the adjacent main roads through the first right turningpassages; an entrance lane of any main road is also provided with a corresponding second right turning passage; the second right turning passages communicate with the corresponding first right turning passages of the entrance lanes of the adjacent main roads; and the second right turning passages also communicate with the corresponding second right turning passages of the entrance lanes of the adjacent main roads. According to the rotary intersection traffic structure, as interleaving conflict points are fixed in positions of entrances and exits, the running distances of straight-going vehicles and left turning vehicles within a rotary road are reduced, the traffic capacity of a rotary intersection can be improved, and the vehicle passing efficiency can be enhanced.

Description

technical field [0001] The invention relates to the technical field of road intersection design, in particular to a roundabout traffic structure. Background technique [0002] In densely populated cities, traffic jams and traffic accidents have become bottlenecks that plague urban development, and most of the traffic jams and traffic accidents are at intersections, especially during rush hour, when intersections are blocked and deadlocked. Greatly reduced road capacity. [0003] At present, the usual practice is: to avoid conflicts by building overpasses at intersections or viaducts on main roads to run through the city; to improve traffic performance by establishing underground passages to separate motor vehicles, non-motor vehicles, and pedestrians. [0004] Although the above method alleviates the traffic pressure to a certain extent, there are still many problems: the way of building the bridge occupies a large area, requires a lot of manpower and material resources, an...

Problems solved by technology

[0005] The purpose of the present invention is to provide a traffic structure at a roundabout that can effectively improve the traffic efficiency of motor vehicles at the intersection, so as to solve the problem of long construction period and large capital investment caused by the existing way of building bridges or adopting the way of building underground passages. question
