Understanding urban commuters: How are non-SOV commuters different from SOV commuters?

Document Type



Public sector efforts to cope with traffic congestion have met with limited success, and congestion problems are likely to grow worse as urban areas continue to grow and Americans remain attached to driving alone. This study explores the characteristics of urban commuters in Washington State in order to cast light on why some people have switched from driving alone to some alternative mode of commuting. What factors--internal to their beliefs and values and external in their context for making decisions about commute trip modes of travel--distinguish switchers from single-occupancy-vehicle (SOV) commuters? The study also assesses the influence of the Washington State Commuter Trip Reduction program on switchers and on commuter mode choices, more generally.
