调查了电动车和自行车之间的超车事件，并探索已有非机动车设施内超车事件数和交通参数之间的关系。应用摄像机观测了3个南京机非隔离的非机动车道路段，并详细分析了包括流量、速度和超越事件特征在内的实际数据。通过数据分析和拟合发现：超车事件与速度差别以及自行车比例相关性较弱；高斯函数可以较好地描述超车事件数和流量（密度）之间的关系；非机动车道的利用水平影响到超车事件密度曲线的拐点位置。研究结论可应用于混合非机动车流中超车事件数的计算和机非隔离非机动车道的宽度设置。

This paper investigates the passing events between electric bicycles and conventional bicycles and explores the relationships between passing events and traffic parameters in bicycle facilities.Three exclusive bicycle paths in Nanjing, China,were observed with cameras.Then,the field data including vehicle number,velocity characteristics and passing event features were analyzed in detail.Data analysis and fitting reveal that the speed difference has little impact on the passing event number,as does the bicycle ratio.The Gaussian function can better describe the relationship between the passing event number and bicycle volume (density).The valid use level of bicycle path width influences the inflexion of the passing events-density fitting curve.The conclusions can be applied for estimating the passing events in mixed bicycle flows and for choosing a suitable width of separate bicycle path.
