Car dependence is widespread in the U.S., creating significant social and equity challenges. Using the case of older adults to illustrate transportation mismatch and the populations most affected, Dr. Li introduces the concept of “accessibility capability,” which takes a holistic view of how transportation and land use can connect older adults and other socially disadvantaged groups to essential destinations. Using North Hollywood in Los Angeles as an example, Dr. Li highlights the barriers to implementing this vision, showing how linking affordable housing and transit-oriented development often faces practical challenges. Building on these national and local insights, Dr. Li will turn to the broader challenges in transportation decarbonization in the electric vehicle era and explore institutional pathways that can support more sustainable and equitable transportation systems. Together, these perspectives inform future research on the politics and governance of sustainable transportation. They also highlight how community-based, collaborative approaches can help overcome persistent barriers.
