Transport hub system for concurrent free flow of sixteen directions at crossroad

Abstract

The invention discloses a transport hub system for concurrent free flow of sixteen directions at a crossroad, which is composed of a concave lane and an arch bridge form effective height for car running, and four left change lanes are arranged at the bottom of an approach bridge of the arch bridge and at the corner of a pier, thereby really realizing the concurrent free flow of the sixteen directions at the cross road, greatly increasing the car running speed, basically solving the traffic bottleneck problem, effectively reducing the vertical height and the span of 50 percent of bridge climbing and the depth of the concave lane down grading, saving land use without affecting city appearance and scenic visual field, maintaining the coordination and elegance of the surrounding environment, and providing a good development platform for the prosperity of the city; and the adoption of guard rail web strips, pedestrian overpasses or tunnels and nonmotorized vehicle lanes and the implementation of man and car separation basically avoid the occurrence of tragic accidents that a man is hit by a car, the occurrence probability of the traffic accidents is greatly reduced. The system of the invention is widely applicable to the construction of traffic road junctions, in particular to the reformation and reconstruction of the cross roads in old cities and inner cities of a metropolis.

Description

technical field

[0001] The invention relates to a tunnel-concave bridge of a traffic hub system at an urban crossroad, belonging to the field of municipal traffic road construction. Background technique

[0002] At present, with the acceleration of the global urbanization process and the popularization of vehicles, using cars instead of walking has improved the speed and efficiency of modern people's work, and cities generally have several or more than a dozen overpasses, which is very important for the transportation of the entire city. Undoubtedly, it is a drop in the bucket, the bottlenecks at the intersections in front of it - the red lights have blocked the winding car queues, the serious traffic jam situation in the metropolis has reached the point where it is necessary to implement comprehensive renovation (technical transformation) at the intersections, especially in Beijing In modern metropolises such as Guangzhou, Shanghai, Shenzhen, etc., where traffic and people ...
