Increasingly city planners, policymakers and academics have recognized the important role behavior plays in travel decisions. A large body of work now recognizes modal choice as a suite of options that may be tied to habit but also that fluctuate based on built environment factors, personal preferences and situational dynamics. Literature also now indicates that humans may irrational decisions based on the apparent certainty of a plan of travel or overly optimistic approach to their travel decisions. This paper explores the literature on travel, behavioral economics, mode substitution behavior and financial versus social norms. It discusses the results from three behavioral experiments that indicate the power that social nudges have in framing sustainable travel behavior. This has policy implications for how planners and policymakers approach sustainable travel options, incentives and programs aimed at reducing emissions and increasing physical activity.
