摘要

This paper summarises part of an assessment of left-turn vehicle (USA right-turn) versus pedestrian crashes atsignalised intersections across Metropolitan Melbourne, Australia conducted for VicRoads (the State RoadTransportation Agency).Study objectives for this paper include:Evaluating data on the relative safety performance for pedestrians of different left-turn treatments; andIdentifying any patterns in the crash types observed for each treatment to see if they suggest possible designimprovement opportunities.This paper:Compares the proportion of crashes at each treatment type versus the proportion of this treatment at allsignalised intersections on the Melbourne Metropolitan road network (as volume-based crash rates areimpractical for a sufficient sample size); andExamines the detailed characteristics for each crash.The findings included:195 pedestrian crashes involving left-turn vehicles were recorded at signalised intersections in 5 years;Slip lanes experienced 22% of crashes with 30% of treatments;Exclusive stand-up lanes represent 18% of crashes and 20% of treatments;Shared stand-up lanes represent 60% of crashes and 50% of treatments; andDistinct conflict patterns were detected for each treatment type, suggesting possible improvements inoperation or design (e.g. 79% of slip lane crashes featured pedestrians approaching from the driver's left).Further research opportunities were identified including:Refining the categorisation of left-turn treatments, addressing the possible bias of slip lane provisiontoward low activity areas and examining other crash types (e.g. vehicle-vehicle).
