中文摘要:
      为研究社区居民适宜步行距离阈值,在上海市进行小区内RP(Revealed Preference)调查,通 过询问居民前往某处目的地的出行方式,实际测量居民住处到目的地的距离,得出步行距离;然 后在虹桥火车站进行可接受步行时间的调查。综合步行距离和步行时间的数据,结合偏态分布与 距离衰变方程的分析方法,得出适宜步行距离与步行使用率的关系式,并通过计算得到了距离阈 值。结果表明,由可接受步行时间调查计算得到的极限步行距离阈值为1 500m,适用于城市规划 的整体设计阶段;由步行距离调查数据计算得到的极限步行距离阈值为950m,可用于具体功能 区的选址及交通衔接方式的选取;选取步行累计使用率为10%时对应的步行距离787m为适宜步 行的距离阈值。
英文摘要:
      The RP survey was conducted in districts of Shanghai to get the data of walking distance threshold, by asking residents′ trip mode to particular destination and measuring of the actual walking distance between the destination and residents′ shelter. Another questionnaire was carried out at Hongq⁃ iao Transportation Hub to get the acceptable walking time. According to the data of walking distance and acceptable walking time, combining skewed distribution methods and distance decay equation, relation⁃ ship between reasonable walking distance and usage of walking was calculated and two walking distance thresholds were obtained. The results show that calculated according to the survey of acceptable walking time, the limited walking distance is 1 500 meters, which could be used in overall design phase of urban planning; calculated according to the survey of walking distance, the limited walking distance is 950 me⁃ ters, which could be used in selecting the location of specific functional area and traffic connection mode; the 787m walking distance which corresponds to 10% walking cumulative utilization rate is cho⁃ sen as reasonable walking distance threshold.
