摘要
给出了等效通行能力调查分析的详细过程,并对调查道路选择和数据分析方法等一些关键环节进行了深入讨论,指出调查道路长度至少应在800 m以上,条件允许时应在1 200m以上,数据分析可采用线性的Greenshields密度-速度关系模型进行.
The detailed processes of survey and analysis of the equivalent capacity are depicted in this paper. Discussion on some important problems of the processes, such as the selection of road length, the form of traffic flow model, and so on, are emphasized. The results show that the perfect length of studied road will be more than 800 meters longer,more preferably 1 200 meters if possible. The Greenshields model can be used for data analysis.
