摘　　要：右转车道作为重要的交通基础设施,对提高右转车流效率具有重要作用,但其空间布局会影响行人与骑行者的非法过街行为。以2种类型右转车道为研究对象,利用无人机和OSMO同时拍摄的方式获取了6个右转车道区域2 890名非机动化交通参与者的过街轨迹和个人特征数据,利用巢式Logit模型分析右转车道类型、交通环境及个体属性等因素对非机动化交通参与者过街行为的影响,并对内在影响机制进行分析。结果表明:相对于分车绿带左侧的右转车道,位于右侧的右转车道区域行人与骑行者的非法过街行为更少,当右转车道位于分车绿带左侧时,参与者倾向在划定的等待区外等待(非安全等待比例55.2%,安全等待比例44.8%);当右转车道位于分车绿带右侧时,参与者更多集中在划定等待区等待(非安全等待比例30.6%,安全等待比例69.4%);而且,分车绿带右侧的右转车道上过街群体的正常通行比例更高,闯红灯比例降低。主要原因是分车绿带右侧的右转车道车流距离过街群体更近,行人和骑行者感知到更多危险,阻止其做出非法过街行为。交通环境、人口统计特征和行为状态也会影响行人与骑行者的过街行为,结果佐证了前期相关研究结论。该研究为右转车道规划及优化、交通管理政策的制定提供了方向参考。Right-turn Lane,a pivotal traffic infrastructure,enhances the efficiency of right-turn traffic flow.However,their configuration can influence the crossing behaviors of pedestrians and cyclists,particularly in instances of unauthorized crossings.Therefore,this study investigates the influences of two distinct right-turn lanes on their crossing behaviors.More specifically,this study utilizes drones and OSMO to collect crossing trajectories and personal attributes of 2890 non-motorized traffic participants across six right-turn lane regions.The Nested Logit model is applied to assess the influence of right-turn lane configuration,traffic conditions,and individual attributes on these participants'crossing behaviors,further delving into underlying reasons.Findings suggest a reduced frequency of unauthorized crossing behavior in right-turn lane regions on the right side when compared to those on the left side of the separation regions.For left-side configurations,participants often wait outside designated regions(55.2%unsafe vs.44.8%safe waiting ratios).Conversely,for right-side configurations(situated between the motorway and non-motorway),a larger proportion adhered to the designated waiting areas(30.6%unsafe vs.69.4%safe waiting ratios).Additionally,right-side configurations display a higher percentage of participants adhering to traffic rules and a decrease in red-light violations.A primary reason for these observations is the proximity of traffic flow to crossing pedestrians and cyclists in right-side configurations,which elevates perceived risks and deterring unauthorized crossings.Besides,some factors such as traffic conditions,demographic details,and behavioral patterns also conducted significant impact on participants'crossing behavior.The insights gleaned from this investigation offer valuable guidance for optimizing right-turn lane designs and formulating more effective traffic management policies.
