Research Cited Left U-turn Median Strip Away The Opening Pitch

Far cited turn left turn traffic organization to make a direct left turn vehicles first straightreuse central intersection downstream wide median U-turn rotation, and indirectly to turn leftinto a right turn, effectively share the load in the capacity of a relatively large part of thetraffic load of road intersections to improve the efficiency and safety of the vehicle is running,is one of the important ways the current urban roads ease traffic congestion. Because far citedturn left turn will increase the main road of turning left vehicle detour distance, so areasonable central median opening spacing become one of the important content of the study.This article first point of conflict left turn vehicles analyzed in detail, and then propose adriveway functional partitioning far cited intersection concepts and urban trunk road.Analysis far cited left turn traffic organizational principles and urban trunk road accessmanagement basic principles, leads to far cited turn left turn traffic organization of theapplicable conditions.And contrast far cited the process, turn left to run the analysis according to the vehicledirectly left, far cited traffic characteristics turn left turn traffic flow and driver behavioranalysis of the advantages and feasibility of further clarify far cited turn left turn trafficorganizational behavior practiced.By analyzing the central median opening spacing factors and learn from foreign centralmedian opening spacing standards imposed on our country far cited turn left turn trafficorganizational behavior laid the theoretical foundation. Focus on the correlation analysisweaving section runs to determine the median strip opening pitch size.Combined to calculate a simple example and use VISSIM simulation validation, furthervalidates borrow weaving section intertwined distance calculations to determine the far citedturn left turn median strip opening pitch accuracy and science, as far cited turn left turn inUrban Road application provides a frame of reference.
