The thesis provides a brief introduction to congestion pricing's theoretical roots and the history of its application. It derives the essential paradigms of the two professions that implement pricing schemes, planners and engineers, from their respective ethical codes and professional policies and applies them to three case studies. This is done to determine the professions roles and to indicate the interaction of the professions in the cases. The three cases were chosen due to their uniqueness and recent application. Lastly, the historical data, derived paradigms, and information from the case studies is assembled, compared, and contrasted to form a model for congestion pricing implementation. The model details actions that planners can take to influence congestion pricing implementation by addressing funding and public acceptability issues at both the federal and local levels. The model can be used by planners, engineers, and decision makers alike to increase the effectiveness of pricing schemes and to make better informed decisions regarding congestion pricing in their community. / Department of Urban Planning
