发生事故导致车道被占用，为考察其对道路通行能力的影响，统计每60 s 内的车流量，利用相关公式计算每个时段的基本通行能力，再乘上折减系数得到实际通行能力；通过正弦曲线拟合获得通行能力随时间变化的关系；运用双样本正态均值分析，比较两次事故的通行能力差异；引入随机排队模型，计算随时间变动的排队长度，并由此得到当队长达到140 m所需要的时间。
髮生事故導緻車道被佔用，為攷察其對道路通行能力的影響，統計每60 s 內的車流量，利用相關公式計算每箇時段的基本通行能力，再乘上摺減繫數得到實際通行能力；通過正絃麯線擬閤穫得通行能力隨時間變化的關繫；運用雙樣本正態均值分析，比較兩次事故的通行能力差異；引入隨機排隊模型，計算隨時間變動的排隊長度，併由此得到噹隊長達到140 m所需要的時間。

In order to examine its impact on road traffic capacity after one lane is occupied by the accident, the paper calculates the traffic within every 60 seconds and the basic capacity for each period with related formula, and then obtains the actual capacity when the basic capacity is multiplied by the reduction factor. The traffic capacity changes over time are given with the sine curve fitting. From two-sample normal mean analysis, the author compares the traffic capacity differences between the two accidents. When the random queuing model is introduced, the author calculates the length of the queue over time, and thus the time need-ed is given if the queue is 140 meters long.
