Straf also suggested measures from the perspective of the consumer of transportation services. Relocation decisions by individuals, households, and families affect and are affected by the transportation system. He hopes that one day there will be a major national survey of households that follows them over time, long periods of time, for many of their economic decisions and choices—in particular, the changes in the use of transportation services and the choices made among them. It would be good to start with some prototypes and ideas of what measures we would like to see in such a survey.

Janet Norwood closed the workshop by noting that when developing indicators, it is important to know their audience and their purpose. Even if data are gathered and packaged on a national level, it is important to have disaggregated data available, because such data affect the ways in which people use and think about transportation. Data for individual areas are hard to come by, and, even though every state has data, the data are not always comparable. These are problems that BTS needs to work through in order to obtain interesting and useful indicators.
