摘　　要：汽车实际燃料消耗量受道路结构和交通流量影响大。为了准确地评价汽车在实际城市路况下的燃料经济性,需要对城市道路路线进行选择并根据路况信息进行典型城市行驶工况提取。分析了合肥市道路结构和交通流量特征,确定了路线选择基本原则。论文研究方法综合考虑了地方道路特征并体现了实际交通流影响,避免了随机确定路线的主观影响,该方法具有通用性。Road structure and traffic flow have a significant effect on the actual fuel consumption. In order to accurately evaluate vehicle fuel economy under the actual urban road, the urban road route needs to be selected and furthermore the urban driving cycles to be determined. In this paper, Hefei City was taken as an example to analyze the road structure and the traffic flow, and the fundamental principle for route selection was confirmed. The special road distributed characteristics have been considered comprehensively for the research method used in this paper, and what＇s more, the method also reflects the actual traffic impact. So it avoids the subjective influence of randomly determination of the test route. In short, this method possesses a wide application.
