Traffic configuration structure of grade intersection

Abstract

The invention relates to a traffic configuration structure of a grade intersection, which comprises entrance lanes and exit lanes, wherein the entrance lanes comprise left turn lanes, straight lanes, specific traffic flow right turn lanes and conventional right turn lanes; the exit lanes comprise right exit lanes relative to the entrance lanes; the right exit lanes comprise right lanes, middle lanes and left lanes and are provided with specific lane ground points; division islands are further arranged between the straight lanes and the specific traffic flow right turn lanes; guide islands are further arranged between the specific traffic flow right turn lanes and the conventional right turn lanes; portal traffic sign board are erected at the opposite front ends of the division islands and the guide islands; the specific traffic flow right turn lanes are communicated with the specific lane ground points by guide lines. The structure has the advantages that diversion and right turn guide is timely and accurate; the problems that cars in the conventional right turn lanes cannot enter the specific lanes or are required to run in an interweaved manner even if the cars can enter the specific lanes are solved; the overall operating efficiency of the grade intersection is effectively improved.

Description

technical field [0001] The invention provides a traffic configuration structure of a level crossing, in particular, a traffic configuration structure of a level crossing in which controlled traffic diversion turns right to solve the interweaving of exit roads. Background technique [0002] At present, our country is in a period of rapid urbanization development. The scale of cities continues to expand, the number of cars increases rapidly, and the short-term, rapid and unbalanced growth of traffic demand not only promotes the rapid development of urban traffic, but also brings traffic congestion to cities. represent many issues. In recent years, traffic congestion has become the main bottleneck restricting the sustainable and intelligent development of cities in our country, which directly induces traffic problems that need to be solved urgently, such as the increase in traffic accident rate and the aggravation of environmental pollution. [0003] As the throat and hub of r...

AI Technical Summary

Problems solved by technology

Due to the insufficiency of traffic design and the inability of timely and accurate diversion information to allow drivers to make correct judgments in a short reaction time, the traffic flow that turns right into a specific channel and the regular right-turn traffic flow are often intertwined, resulting in the speed of right-turn vehicles. The capacity of the right-turn lane is reduced. When the traffic volume reaches a certain level, local traffic congestion can evolve into traffic congestion at level crossings, reducing the overall operating efficiency of level crossings.
