摘　　要：城市道路混合交通中,自行车对机动车行驶有显著的干扰影响.文章将自行车对机动车的影响划分摩擦干扰和阻滞干扰两种状态,通过采集北京市三个典型路段的混合交通干扰数据,定量分析了不同自行车干扰状态下机动车速度的变化趋势,以及速度分布频率,定义并计算了干扰状态相变的临界点:干扰变化阀值,进一步计算了可对不同道路条件下干扰程度进行比较的摩擦干扰系数和阻滞干扰系数.基于样本的研究结果表明,自行车对小汽车和大客车的影响程度有显著的差别,同时机动车在摩擦干扰和阻滞干扰两种状态下的行驶速度特征有明显的不同.Bicycles create obvious impact on motor vehicles＇ behavior on urban road especially in China with mixed traffic. These influences can be divided into two states： friction and block interference, Based on the data of interference of bicycles on vehicles＇ driving in typical road section in Beijing, this paper quantitatively analyzes the velocity changing tendency of vehicles under different interference, velocity distribution frequency, and critical trans- formation of different interference state. The friction and block interference coefficients are also worked out, which are useful to compare interference degrees under different road conditions. As a result, the research based on sample data shows that the velocity distribution of vehicles has different characteristics under different interference state, and vehicles driving velocities are significantly different under the friction interference and block interference.
