摘要： 为研究侵犯性驾驶行为对城市局部区域交通通行的影响及影响程度，选取北京市4 个典型道 路交叉口进行1 周观察。借助录像设备记录早高峰、平峰、晚高峰3 个时段三类常见的侵犯性驾驶 行为：侵占公交专用车道、随意变换车道、插队。数据显示：随意变换车道发生的次数最多且多数 交叉口各时段间有显著差异；平峰时段侵占公交专用车道更为明显；各时段插队次数比较平均。为 探究侵犯性驾驶行为对道路交叉口通行能力的影响，提出交叉口平均负荷能力(ALC)和侵犯性驾驶 行为负荷(ADL)两项指标。计算结果与预期假设不同，具有侵犯性驾驶行为的车辆没有阻碍道路交 叉口的车辆通行。

Abstract： To study the impact of aggressive driving on traffic capacity of local roadway network, traffic flow performance at four typical intersections in Beijing were observed for a week. Three common aggressive driving behaviors, occupying exclusive bus lanes, illegal lane changing, and cutting in line, are videotaped during morning peak, non-peak and evening peak hours. Results shows that illegal lane changing occurs the most and its frequency varies significantly at most intersections during different time periods. Occupying exclusive bus lanes is common during non-peak hours, and the occurrence of cutting in line shows little temporary difference. To estimate the effect of aggressive driving behavior on intersection capacity, this paper proposes two indices, namely average load capacity (ALC) and aggressive driving load (ADL). The study results show litter impact of aggressive driving, which contradicts the study hypothesis.
