Characteristics Analysis of Lane Changing Behavior Based on the Naturalistic Driving Data
摘要
Abstract
In order to study characteristics of drivers′lane changing behaviors,including lane changing frequency, motivations,gazing behavior and turn signal usage,drivers′behavior and vehicle operating data are collected from Shang-hai naturalistic driving study.Lane changing is identified by lane departure and its variables are thus extracted.Character-istics of lane changing behavior are analyzed and compared between different types of road.Lane changing behavior con-stantly occurs on urban arterial road,with a frequency of 0.82 per kilometer.The rate of the multilane changing on the freeway is relatively higher,being a potential threat to the drivers.Comparing with the study results by Olsen et al.,it appears that drivers rarely carry out"shoulder check"the blind spot before lane changing behavior although,the percent-age of side mirrors check and use of turn signal is relatively high.Potential risks exist in the frequent lane changes,multi-lane changing and blind spot ignorance,which deserve further studies.关键词
