Understanding of Relationships Among Key Sustainability Measures in Transportation: Using Influence Diagrams

As the word “sustainability” becomes more and more prevalent throughout various disciplines, the definition of a sustainable transportation system is still controversial. However, there is emerging consensus that transportation system sustainability should capture attributes of system effectiveness and system impacts on economic development, environmental integrity, and the social quality of life. This study aims to 1) define causal relationships between important sustainability parameters using an influence diagram and 2) discuss the systems interactions between/among common domains of sustainability. These diagrams should at the very least serve as an overview guide for decision makers who attempt to incorporate sustainability considerations into transportation planning and understand key factors of sustainability and their relationships. It is also important that decision makers do not consider transportation system sustainability in isolation from related broader issues beyond transportation planning in a region since these key sustainability dimensions are not entirely isolated. When considered collectively, the nature of “sustainability” tends to be better understood and the progress in movement toward or away from sustainability can be monitored as a whole.
