Municipal crossroads structure

Abstract

Disclosed is a municipal crossroads structure, wherein a first artery (1) and a second artery (2) form a central platform (3) at an intersection, the first artery (1) is provided with a low tunnel (4) passing underneath the central platform (3), a cross turning tunnel (5) is diverged from the low tunnel (4), and a height of the two types of tunnels enabling vehicles to pass therethrough is no less than 2 meters and no more than 3 meters. The first artery (1) is separated by the low tunnels (4) into two ground surface lanes (7, 8) which are intended for travel in opposite directions and can be used by large vehicles, the two ground surface lanes (7, 8) are connected on the central platform (3) to form U-turn lanes (9, 10), and the U-turn lanes (9, 10) are located on left and right sides of a straight-on lane of the second artery (2) on the central platform (3). The municipal crossroads structure uses the low tunnels (4), the cross turning tunnels (5) and the central platform (3) to enable split-flow for small and large vehicles and vehicles travelling in different directions, such that a large number of small vehicles can travel without being caught in a traffic jam, and traffic is smooth across the whole crossroads.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a municipal road structure, and particularly to a municipal crossroads structure.BACKGROUND OF THE INVENTION[0002]The best traffic is reflected by smooth traffic at an intersection. At present, municipal crossroads mainly employ road structures such as planar crossing, roundabout, viaduct, multi-layer interchange or high headroom tunnels. However, these current road structures have their respective drawbacks and cannot effectively solve traffic jam issue of a city. For example, on crossroads employing planar crossing, traffic lights need to be used to control the passing of vehicles in turn, gather vehicles up and then release them, as a result that traffic jam probably occurs at the crossroads. Furthermore, drivers' rush to pass the crossroads during a green light duration or run the red light to save time is likely to cause accidents such as rear-end collision or turn collision and thereby cause serious losses such as pe...

AI Technical Summary

Benefits of technology

The present invention provides a crossroads structure that can solve traffic jams. The structure has a central platform and low tunnels that help direct traffic flow and avoid large vehicles from slowing down the traffic speed. The low tunnels are no more than 3 meters high, reducing construction workload and costs. The crossroads structure occupies less land resources and is easy to spread to most high-traffic flow crossings of the whole city, thereby solving the bottleneck effect and enabling the traffic of the whole city to become smoother. In an improved solution, the low tunnels have a shallow depth, reducing the cutting of soil and mud, and a raised rainwater isolating belt prevents water ponding and improves safety for vehicle travel.

Problems solved by technology

The crossroads structure can substantially reduce stay time of vehicles at the crossroads, requires small investment of funds, and exhibits small engineering workload and short construction duration.
