Representation of built environment and relationship to travel outcomes

Kreider, Tyler January 2011 (has links)
The built environment has been recognized as one of the major factors influencing travel behavior, but research into the specifics of how the built environment is represented is scant. This thesis investigates this relationship through different modes of representation. The first chapter offers an introduction to the topic, objectives, and research issues. In the second chapter, an original speed study is used to investigate the link between built environment and geometric design variables on vehicle operating speed along local roads. After controlling for traffic conditions, it was found that built form variables have a weak link with vehicle speed, geometric design being the main determinants. Chapter Three improves upon built form representation by using a neighborhood typology to simultaneously model household choice and GHG emissions. A lingering problem, however, is in the way in which land use mix is measured. Thus, the third chapter presents an entirely new method of measuring land use mix, which relies on interaction of complementary uses as opposed to proportion-based measurement. A preliminary evaluation of this method has proven that it is a great improvement on what is currently used to measure land use mix. The methodologies and case studies in this thesis demonstrate progress that has been made in how the built environment is represented in transportation studies, and it is hoped that they are a positive influence in the field. / L'environnement bâti est reconnu d'avoir une influence majeure sur les habitudes de déplacements, mais la recherche sur la représentation de cet aspect n'est pas bien développée. Cette thèse est une collection de trois manuscrits qui enquêtent sur cette influence dans des modes de représentation différents. Le premier utilise les variables de l'utilisation du sol simple et de la population à fin de modéliser la vitesse des véhicules sur les rues locales. Il était trouvé que ces variables ne suffisent pas d'expliquer la vitesse des véhicules donc ils étaient éliminés de la modèle. La deuxième étude améliore la représentation de l'environnement bâti avec une typologie de quartier pour estimer une modèle simultanée du choix de location du ménage et les émissions des GES. Cependant, un problème qui reste est dans la mode de mesurer la mixité des utilisations du sol. Donc le troisième article présente une nouvelle méthode de mesurer la mixité qui est basée sur l'interaction des usages complémentaires par opposition à une mesure des proportions. Elle était évaluée d'être une amélioration sur la méthode utilisée actuellement. Ces trois articles montrent le progrès fait dans la représentation de l'environnement bâti pour les études en transport, et ils peuvent avoir une bonne influence dans la recherche future.
