| 摘 要： | 通过现场调查,从定性和定量两个方面对城市道路路段拥挤交通流特性进行研究,以获得客观评价城市交通拥挤与明确交通拥挤实际状况。实际调查具有典型代表特征的路段,采用摄像观测法进行交通调查与数据采集,在分析造成拥挤成因的基础上,对调查数据进行处理,从地点车速、行程车速、交通量等指标进行分析,并与非拥挤状态交通流进行比较,发现拥挤状态下交通流特性具有显著的差异,而车型在拥挤交通流中也是一个重要的影响因素。

| Abstract: | Based on the field investigations,both qualitative and quantitative research on the congested traffic flow characteristics of the sections of urban road was made through an objective evaluation and knowledge on the urban traffic congestion.Typical road sections were selected and VCR was made full use of observing to do traffic survey and data collection.On the basis of analyzing the causes of congestion,the survey data are processed from the location velocity,the travel velocity,traffic volume and other ind... |
