ABSTRACT

Transportation is not a science, but a ¿ eld of inquiry and application. As such, it tends to rely on a set of speci¿ c methodologies since transportation is a performance-driven activity and this performance can be measured and compared. Transportation planning and analysis are interdisciplinary by nature, involving among others, civil engineers, economists, urban planners and geographers. Each discipline has developed methodologies dealing with their respective array of problems. Still, transportation is an infrastructure-intensive activity, implying that engineering has been the dominant methodological paradigm for transportation studies.
