Control method for automobile turning left at access gate of highway section buildings

Abstract

The invention discloses a method for controlling left turn of a vehicle at a gateway of a road section building by utilizing a median separator. In the method, a median separator(3) is arranged in the middle of a road(1), and a vehicle turning road(5), a turnaround road(4) and a pedestrian and bicycle road(6) are arranged in the median separator(3); roads on both sides of the median separator(3) are communicated; due to the arrangement of the median separator in the road section and the arrangement of the vehicle road and the pedestrian and motorless vehicle road on the median separator, an indirect turning-left channel is provided for vehicles which are forbidden to turn left to drive out of the building, the number of conflict points caused by the direct movement and the left turning of vehicles are reduced, and simultaneously the interference on vehicles due to the crossing of pedestrians and motorless vehicles on both sides of the building is avoided, thereby facilitating the improvement of traffic efficiency and the lowering of accident threat.

Description

technical field [0001] The invention relates to a control method for motor vehicles turning left at road section building entrances and exits by using a road central divider, and relates to the technical field of urban traffic system planning and management. Background technique [0002] With the rapid development of China's economy and society, people's requirements for traffic quality are getting higher and higher. Speed, convenience, and safety are the expectations of every traveler, and the good operation of road traffic is the basic guarantee for the above expectations. However, in order to pursue the convenience of self-traffic trips, many units directly set the entrances and exits of buildings on the main traffic roads (as the inventor found in the research of "Yangzhou City Road Traffic Safety Planning" that he completed, the existing main roads in Yangzhou City There are 69 building entrances and exits on the 6-kilometer section of Yangling Road). Due to the lack of...

Problems solved by technology

However, in order to pursue the convenience of self-traffic trips, many units directly set the entrances and exits of buildings on the main traffic roads (as the inventor found in the research of "Yangzhou City Road Traffic Safety Planning" that he completed, the existing main roads in Yangzhou City There are 69 building entrances and exits on the 6-kilometer section of Yangling Road). Due to the lack of technical measures for traffic organization, these sections have become typical traffic congestion bottlenecks and traffic accident-prone points

[0003] The analysis of relevant literature shows that the main reason for the formation of traffic congestion and frequent accidents at road sections and building entrances and exits is that it increases the complexity of road section traffic operations
