The report presents the results of a study to evaluate the impact of an exclusive reversible roadway for preferential treatment of high occupancy vehicles. The objective of the study was to evaluate and document the impacts of implementing operational changes on the Shirley Highway express lanes on the transportation system in Northern Virginia. The study documented the magnitude of the changes which have occurred to the number of persons using the express lanes, the impact on the use of the regular lanes, vehicular and person miles of travel, and occupancy levels of both bus and auto. It was determined that the provision of an exclusive roadway for use by high occupancy vehicles has proven to be a successful incentive for formation of carpools and vanpools; the high minimum size carpool (4 or more) has not proven to be a drawback in the increased use of carpools; and when there is demonstrated time savings, users of the facility will be attracted from zones outside the normal corridor area.
