Surveys ask individual respondents to provide data about their own actions and experiences directly. There are several different types of surveys: ƒ Origin-destination survey, also known as a revealed preference or travel behaviour survey, quantifies people’s travel patterns by asking them to describe their actual travel activity (i.e., what they actually did) over a specified period of time. Information typically is gathered about the trip’s origin, destination, purpose, mode(s) used, start time and end time. ƒ Stated preference survey quantifies how people would behave under a situation with which they do not yet have any experience. Stated preference surveys typically are used to quantify how people value travel time saved for a new toll road (i.e., their willingness to pay a toll of $X in order save Y minutes of time), or the willingness of transit patrons to make a transfer to a new, faster rapid transit system, which might replace taking a slower bus all the way (i.e., the inconvenience of having to transfer mid-way in a trip, even if that trip is now faster or more comfortable). ƒ Attitudinal surveys also assess why people make the travel decisions they do, and how they might behave in a new situation, among other attributes (e.g., customer satisfaction with an existing programme). While this assessment is qualitative, it provides useful information for programme managers
