This study examines the ethical challenges that exist for travel demand forecasters. It first looks at bias in travel demand forecasts. This is followed by a discussion of the ethical dimensions of travel demand forecasting. The study next sets the theoretical groundwork by developing three consistent working hypothesis which provide alternatives to the common assumption that corruption is responsible for biased forecasting. The next chapter provides the methodological details of the study, which are comprised of a mail survey and a series of in-person interviews with travel demand forecasters. A multidimensional model of practice from modelers' narratives about ethics, professional motivation and job satisfaction is then constructed. The study concludes with an analysis of the study topic looking at bias, misuse, ethical behavior, archetypes, and the possibility of venality.
