Process Data for Understanding and Modelling Travel Behaviour

Abstract

This chapter makes a case for more widespread collection and use of process data to support transportation policy, both directly and indirectly, through travel demand modeling. Travel surveys generally collect information on the outcomes of decision processes. Trip/activity diary surveys, for example, tell us about the locations people decide to visit, the things they decide to do there, and the models they decide to use to get there. The surveys tell us little or nothing about how the people came to those decisions.
