Increased effort and funding to reduce greenhouse gas emissions have led the State of California to incentivize housing development, including affordable housing, near high-quality transit (HQT). Yet there has traditionally been little information about the travel patterns of low-income residents living in affordable housing, making it difficult to accurately estimate the impact of affordable transit-oriented developments (TODs) on vehicle miles traveled (VMT). Researchers have found a combination of land use and built environment factors to influence VMT, commonly referred to as the 5 Ds: distance to HQT, density, design for walkability, destination accessibility, and diversity of land uses, in addition to a series of individual-, household- and building-level factors that this study also reviews.

This study builds on previous research in California on the travel patterns of low-income residents living in affordable units both near (<0.5 miles) and far (>0.5 miles) from HQT in the San Francisco Bay Area and Los Angeles using a multi-method research design. Data were collected, assembled, and analyzed for 292 tenants living in affordable units both near and far from HQT to provide a picture of trip frequency, length, mode, purpose, and vehicle ownership as a function of development characteristics, household demographics, and urban setting.
