High-efficiency passing method for road intersection

Abstract

The invention discloses a high-efficiency passing method for a road intersection. A left turning passage for communicating two-way lanes of a major trunk road is built in the middle section of a straight through isolating band of the two-way lanes of the major trunk road; an approximately quincuncial or oval traffic ring island is formed on the intersection; resources of middle section of the road are thoroughly used for enhancing the passing capability of the intersection; and waste road resources are better applied. Under the condition that no overpass is built on a suburban intersection and a T-junction and buildings along streets are not removed, a left turning vehicle stream and a straight vehicle stream on the major trunk road quickly can pass the intersection without any parking; under the condition that the left turning vehicle stream and the straight vehicle stream on the major trunk road are not disturbed, a left turning vehicle stream and a straight vehicle stream on a secondary trunk road can successfully pass the intersection so that the passing vehicle streams on the intersection are simple and sequential; and 50% traffic light conversion is reduced, therefore, the purposes of largely enhancing the vehicle passing efficiency and realizing quick passing are achieved.

Description

technical field

[0001] The invention relates to a method for improving the space for improving traffic capacity of suburban roads and adopting non-circular traffic roundabouts for efficient traffic at road intersections. Background technique

[0002] At present, due to the rapid development of society and the substantial increase in people's income, public cars and private cars are developing rapidly. However, due to the lag of suburbanization construction and the narrow roads caused by the congenital deficiencies of the original planning, all traffic and people meet the crossroads. The red lights at crossroads and T-junctions basically have to stop, resulting in very congested intersections and T-junctions in every suburb, especially during rush hour, when there are overcrowded traffic and people everywhere, causing everyone to complain. Although the traffic lights at crossroads and T-junctions can control the orderly flow of vehicles, due to mutual interference between str...
