ABSTRACT
Transportation is not a science, but a field of enquiry and application. As such, it tends to rely on a set of specific 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.
