Methodologies for empirical research on the link between the built environment and transit use

Research focused on understanding the relationship between the built environment and transit use is important for optimising urban transportation networks and encouraging sustainable travel behaviours. To produce generalizable insights, empirical studies need to be designed using an overall research strategy that is fit-for-purpose. This is not an easy task, as there are many barriers to knowledge development in the field. This chapter provides an overview of the theoretical frameworks, sampling and estimation methods and indicators relevant to designing empirical built environment and transit use research. Case studies are used to demonstrate the trade-offs that need to be considered when choosing between alternative approaches. The chapter concludes with recommendations and future directions for empirical research aimed at better understanding the built environment and transit use connection.
