中国大都市行人交通特征的实测和初步分析

行人交通是城市交通研究的重要研究对象．观测表明，大中城市的行人交通呈现复杂多变的性态．最近，作者经缜密策划，组织了两组行人交通实测，获得了各类实测数据，包括步速、步幅和步频等．该文描述这些实测和相应的统计分析结果，由此概述我国大城市的行人交通特征．实测数据显示，我国大城市行人的基本数据与国外的情况略有差别，但步速、步频的分布同为Gauss分布，平均步速为1．24m/s，平均步频为1．96steps/s．这些实测结果完善了国内行人交通特征的基本数据，有一定的实用价值．

Observations and Preliminary Analysis of Characteristics of Pedestrian Traffic in Chinese Metropolis

Pedestrian traffic is an important research topic in studying urban traffic flows. Observations indicate that pedestrian traffic in big cities exhibits complicated and variable behaviors. Recently, through meticulous organization, two sets of field measurements were conducted by the authors' group to gain various data of pedestrian traffic in the urban area of Shanghai, including walking speed, steps size and step frequency, etc. In this paper, the surveying process and corresponding statistical results are described, and the characteristics of pedestrian traffic in Shanghai outlined. The observed data show that although there exist slight differences between the pedestrian traffic patterns in China and in foreign countries, the walking speed and steps frequency within crowds possess a similar Gaussian distribution with mean values of approximately (1.24 m/)s and 1.96 step/s respectively. The presented results have perfected the basic statistics of Chinese pedestrian traffic characteristics and hence are of certain practical value.
