How is Commute Mode Choice Related to Built Environment in a High-Density Urban Context? environment and travel behavior in extremely dense urban settings, using Hong Kong as a case study. In addition to investigating how built environment features are related to the choices between public transport and cars, public transportation is divided into three submodes to study the impacts of the built environment. Furthermore, how these relationships differ between millennials and older generations was tested. Results indicate that built environment characteristics are more influential in people’s choices among different public his paper addresses the unique challenges and problems associated with the built T transport sub-modes than in their choice between public transport and cars. Compared to older commuters, millennials’ choices of rail-based and mixed-mode public transport are more susceptible to built environment attributes whereas their effects on road-based transit usage are stronger for older commuters. These investigations provide important insights into individuals’ commute mode choices in highly dense, transit-dominated urban contexts, and hence provide more reliable grounds for policymaking to encourage the usage of specific public transit submodes, and to meet the needs of different age groups.
