Trends in Single-Occupant Vehicle and Vehicle Miles of Travel Growth in the US
Trends in Single-Occupant Vehicle and Vehicle Miles of Travel Growth in the US
Report Number: RRD-030
This digest presents key findings from the recently completed Transit Cooperative Research Program (TCRP) Project H-13B, Trends in Single- Occupant Vehicle (SOV) and Vehicle Miles of Travel Growth in the United States. The research developed trends and predictions of drive-alone commuting in the United States and addressed the policy implications that will be useful to transportation planners and decision-makers. The objective of the study was to provide a stronger quantitative understanding of the factors that have been affecting the dynamics of commuter mode choices and vehicle occupancy levels in recent years, and to assess the role of public policy in the trends observed. On the basis of this quantitative analysis, the study offers comments on the potential efficacy of policies designed to increase transit ridership and/or to increase average vehicle occupancy levels.
