大城市公交车行驶工况研究中的实验路线选择

在汽车行驶工况的研究中，为了使测量、解析得到的工况真实客观、具有代表性，必须重视实验路线的选择．文中介绍了广州市公交车行驶工况研究中实验路线的选择过程。通过实际调查和分析比较，提出了适用于大城市的以平均运送速度和站间运送速度标准差为基础的双因素路线选择方法，并据此方法选取了广州市公交车行驶工况研究的15条实验路线．数据分析显示，这些路线能够代表广州市公交车的行驶工况．

Selection of Experimental Routes for the Investigation into Bus Driving Cycles in Big Cities

In the investigation of the driving cycles of vehicles, the selection of experimental routes is known to be a significant factor in achieving objecitiveness and representativeness of the measured and resolved driving cycles. In this paper, the process of selecting experimental routes for the investigation into bus driving cycles in Guangzhou is introduced. A double-key-factor method for the selection is proposed according to on-site investigations and analyses. This method is based on the average transiting speed and the standard deviation of transiting speed between two stations. The proposed method is applied to the selection of 15 experimental routes for the investigation into the bus driving cycles in Guangzhou. Data analysis result shows that the 15 routes fully represent the bus driving cycles in Guangzhou.
