论文摘要
本文介绍了与区域家庭旅行调查有关的样本量问题的审查。对当前实践的综述表明，在加拿大，美国和国外，对样本量的不同观点和国外存在不同的实践。该论文使用The Transportation Tomorrow调查（TTS）中的数据（TTS） - 一项在大多伦多和汉密尔顿地区（GTHA）进行的家庭旅行调查 - 进行了一系列经验调查，以评估家庭旅行调查样品的充分性。实证研究表明，即使样本量为5％，人口的全部表示及其相应的旅行行为也可能很困难（在95％的置信度下）。因此，根据实证研究的结果和文献综述的结果，本文提出了一个灵活的家庭旅行调查样本规模确定的框架，尤其是对于加拿大市政当局。
The paper presents a review of sample size issues related to regional household travel surveys. A review of current practices reveals that different perspectives and, as a result, different practices exist in Canada, US, and abroad on sample size. The paper uses data from the Transportation Tomorrow Survey (TTS) - a household travel survey conducted every five years in the Greater Toronto and Hamilton Area (GTHA) - for a set of empirical investigations that asses the adequacy of household travel survey samples. The empirical investigations reveal that even with a 5% sample size, a full representation of the population and its corresponding travel behaviour may be difficult (at the 95% confidence level). Therefore, based on the results of the empirical investigations and the literature review, the paper proposes a flexible framework for household travel survey sample size determination, especially for Canadian municipalities.
