许多交通规划者进行当地调查，以更好地了解他们城市或城镇居民的步行和骑自行车水平。本文探讨了设计一个强大的抽样策略，这样的调查的挑战。对现有非机动化交通调查的审查表明，许多现有调查对旨在收集全民骑自行车和步行数据的社区采用了不太理想的抽样方法，从而损害了其结论的力度。要么调查所用的方法过于昂贵和复杂，大多数社区无法实施，要么调查产生的数据不适用于社区的所有居民（即，无法推广到全体人口的数据）。针对这一抽样问题，本文提出了一种新的方法来收集可推广的数据：在行人和自行车调查（PABS）项目开发的抽样方法。PABS提供了一个严格的，但廉价，简单，并有充分的文件证明的方法进行调查。公共预算系统的邮寄-邮寄-回寄调查和概率（可推广的）抽样方法可以在市政机构内部进行。通过使用PABS，运输专业人员可以获得比其他现有方法更高质量的关于其整个社区的数据。因此，对拦截调查（收集关于使用具体设施的数据的一种重要方法）或分发给电子邮件名单的调查（收集定性数据的一种廉价而有用的方法）等其他抽样方法，PABS是一种有益的补充。
Many transportation planners undertake local surveys for a better understanding of the levels of walking and cycling of residents in their city or town. This paper explores the challenges of designing a robust sampling strategy for such surveys. A review of existing surveys on nonmotorized transportation demonstrated that many existing surveys used less than ideal sampling approaches for communities that were aiming to collect populationwide data on cycling and walking and thereby jeopardized the strength of their conclusions. Either surveys used approaches that were too expensive and complex for most communities to implement or surveys generated data that were not applicable to all residents in a community (i.e., data that were not generalizable to the full population). In response to that sampling problem, this paper presents a new method for collecting generalizable data: the sampling method developed in the Pedestrian and Bicycling Survey (PABS) project. PABS offers a rigorous, yet inexpensive, simple, and well-documented method to conduct surveys. The PABS mail-out-mail-back survey and probabilistic (generalizable) sampling approach can be performed in-house within municipal agencies. With the use of PABS, transportation professionals can obtain higher-quality data about their community as a whole than they would obtain with many of the other existing approaches. PABS is thus a useful complement to other sampling approaches such as intercept surveys (an important way to collect data on the use of specific facilities) or surveys distributed to e-mail lists (a cheap and useful way to collect qualitative data).
