摘要

The Pedestrian and Bicycling Survey (PABS) is a mail out/mail back survey designed to be aninexpensive means for local governments to learn about nonmotorized transportation use in theircommunities. An important component of the design of the PABS was creating a probabilisticsampling approach that would be relatively straightforward to administer and, if desired, couldbe carried out in house (within municipal agencies). While other sampling approaches—such assnowball sampling across the internet—can achieve a large number of responses, the probabilityof any person being asked to take the survey is not known making it a challenge to generalizefrom the sample to the wider population. Overall, a probabilistic sample survey can be anachievable and cost effective data gathering approach for local governments, as well as beingpreferred on statistical grounds.
