Abstract
Traffic impact analysis (TIA), which estimates the traffic impacts of proposed land development, tends to bias against higher-density developments in urban areas where traffic is often congested and travel alternatives plentiful. This has important implications for housing supply and affordability, suburban sprawl, and private vehicle dependence. The research team examines the understudied implication of TIA on housing by drawing on empirical evidence from distinct bodies of research in the transportation and land use planning literature to describe the mechanisms through which TIA may affect housing market conditions. The researchers conclude that TIAs likely have negative effects on urban housing production and affordability.
