摘　　要：为了合理设计带提前右转渠化车道信号交叉口,研究了自行车交通流对机动车交通产生干扰的过程及结果.通过视频摄像的方法,在昆明、长春、吉林采集到大量的信号交叉口交通流运行数据,以饱和车头时距为分析指标,分析机动车及非机动车交通流运行特征.结果表明:在绿灯时间初,随着自行车流量的增加,部分自行车将涌入机动车行驶空间,增加了机动车交通流的运行延误.通过构建延误计算模型,对其进行验证,表明该模型具有较高的预测精度.最后应用该延误模型确定了自行车交通流对带提前右转渠化车道信号交叉口通行能力的修正系数计算模型.The purpose of this paper is to better quantify the effects at signal intersections with pre-rightturn lanes.Traffic flow data of several signalized intersections with pre-right-turn lanes in Kunming City,Jilin City and Changchun City of China were collected through videotaping,to analyze the interference between the vehicle flow and bicycle flow.It is found that with the increase of the bicycle traffic volume,the bicycle lanes become congested and bicycle traffic is more likely to encroach into the travel path of motor vehicles,and result in the excessive vehicle delays.On the basis of empirical data,a calculation model was developed to quantify the relationship between the oversaturated bicycle flow and the additional operating delay caused by the bicycles.The result of the analysis can be used to calculate the capacity of the signalized intersections with pre-right-turn lanes and assist in developing guidelines for installation of pre-right-turn lanes at signalized intersections.
