CARPOOLS, VANPOOLS, AND HIGH OCCUPANCY PREFERENCE LANES: COST EFFECTIVENESS AND FEASIBILITY

The report looks at the reductions in vehicle miles traveled (VMT) and air pollution that can be accomplished with voluntary transportation control measures. The measures studied are carpool/vanpool programs and preferential highway lanes for buses and other high occupancy vehicles (HOVL). The report examined transportation control programs in four major metropolitan areas to analyze what factors affect the programs' effectiveness. Based on empirical data and use of a computer model, the report predicts that carpools, vanpools, and HOLV's may reduce car use 2-3% and save travelers millions of dollars. The costs of these programs are generally small compared to their benefits, except where new highway lanes are built for use as potential lanes. However, the study concludes that major reductions in air pollution may not be accomplished unless mandatory traffic controls are also used. The study also describes how people travel to work in 124 major metropolitan areas and includes case studies of carpool, vanpool and HOVL programs in use in both urban and less-densely populated areas.
