| 摘 要： | 通过把记录的车速曲线在连续的停顿处分割成运动学片段的方法来研究交通状况特征。用主成份分析法和聚类技术提炼这些运动学片段的特征。根据统计分析的概率随机选择并重组实际运动学片段，构造了一系列行驶工况。

| Abstract: | The speed-time curve is divided into kinematics sequences, which are used to analysis the traffic features. Principal component analysis and cluster analysis are performed to refine the features of these sequences. By randomly selecting and combining these sequences according to statistical probability, a series of driving cycles are constructed. |
