摘　　要：信号交叉口非机动车车流对机动车车流的影响机理研究,对于交通组织优化及确定信号交叉口通行能力有着重要的意义.文章通过视频摄像的方法,采集到带有提前右转渠化车道的城市信号交叉口的车流运行视频;经过处理分析,得出在不同自行车释放流量下,直行机动车流的车头时距、饱和状态及延误数据;运用分层聚类分析的方法,对实测数据按照机动车车流饱和车头时距、饱和位置、延误、自行车释放流量等指标进行分类,分析得出受同向直行自行车流影响,直行机动车流运行状态分为3种,为进一步量化非机动车对信号交叉口直行机动车交通流干扰奠定基础.The research on the impact of non-motor vehicle traffic flow on motor vehicle traffic flow have a significant meaning on traffic channelization and quantifying the capacity of signalized intersection. The purpose of this study was to analyze the impact of bicycles on straight motor vehicle traffic flow at signalized intersection with advance right-turn lane. Through the videotaping of signalized intersection with advance right-turn lane,the headway,saturation state and the traffic delay of motor vehicle traffic flow were observed. Using Hierarchical Cluster method,the observed data could be classified as five classes and these five classes could be labeled to three states. These work will be available on quantifying the impact of non-motor vehicle traffic flow on motor vehicle traffic at signalized intersections.
