摘　　要：选取北京市36条典型公交车行驶路线，用GPS进行了连续一周的车速采集，累计行程6000多公里，获取了100多万条行驶速度数据。运用聚类分析方法对样本数据进行初步分析，确定了所需的数据样本；再用MATLAB软件进行编程计算，对样本数据进行了整理和分析，最后构建了公交车辆道路行驶工况。对比分析表明它与欧洲地区的行驶工况存在一定的相关性。36 typical public bus routs in Beijing City are chosen for speed acquisition by GPS in 7 consecutive days. More than one million speed data are obtained with a total mileage of over 6,000 km. A preliminary analysis on sample data is done with cluster analysis and the number of sample is determined. Then the sample data are sorted and analyzed by programming and calculation with MATLAB. Finally the typical driving cycle for public buses in Beijing City is constructed. The contrastive analysis indicates that it has certain correlation with the driving cycle in European region.
