As the lead postdoctoral researcher for this project, I oversaw all aspects of survey design, data collection, data processing, and stakeholder engagement. The study examines how residents’ attitudes, built environment characteristics, and available transportation options shape car dependence in a sprawling urban context. We collected survey data from over 25,000 residents across the region to identify key factors influencing car use, including socioeconomic status, access to alternative transportation modes, and perceptions of safety and convenience.

​

The project aims to uncover strategies for reducing car dependence and enhancing multimodal travel in Los Angeles, particularly through shared mobility and public transit integration. By analyzing these data, we aim to inform targeted interventions that promote more sustainable travel behavior and reduce vehicle miles traveled (VMT), supporting decarbonization efforts.

​

Our findings emphasize the importance of a well-connected transit network, investments in bike and pedestrian infrastructure, and addressing social factors like perceived safety and accessibility to decrease reliance on private vehicles. Results will guide policymakers in designing more effective programs and policies that align with California’s climate goals and urban sustainability strategies.
