A Dynamic Analysis of the Built Environment-Travel Behavior Relationship Using Three Activity-Travel Surveys in the Austin, Texas Region

The relationship between the built environment (BE) and travel behavior (TB) has long interested scholars and practitioners in transportation, urban planning and design, health, and other fields. The proposed research aims to advance knowledge of the BE-TB relationship by taking a dynamic analysis approach. The study will pool three activity-travel surveys (1998, 2007, and 2017)

The Differential Accessibility Effects of Work from Home: Travel Behavior Outcomes and Transportation Equity Implications

Researchers have long highlighted the potential effects of telework on the geography of opportunity in metropolitan areas. Telework, despite increasing accessibility to certain job markets, can further cause employment and population to decentralize, facilitating a spatially dispersed pattern of metropolitan growth. This could exacerbate existing disparities and inequities, making it harder for disadvantaged and transit-dependent

Promoting Sustainable Travel within Communities through Behavioral Interventions and Emerging Mobility Solutions

Traditionally, interventions to change travel behavior have relied on penalty-based approaches (such as tolls). Recent discussions have shifted towards monetary incentive-based approaches to promote sustainable modes. However, due to limited funding, relying on monetary incentives alone is not sustainable. Hence, it is important to explore the potential of sustainable non-monetary incentives such as gamification, nudges,
