A compendium of existing HOV lane facilities in the United States

The compendium provides an assembly of available information on existing high-occupancy vehicle (HOV) lane facilities in the United States. While it is comprehensive and thought to include virtually all existing facilities at this time, it is possible that there are isolated instances of facility information that had been omitted from sources used for this document. The compendium is intended as a reference resource for an audience of transportation professionals responsible for planning, designing, funding, operating, enforcing, monitoring, and managing HOV and high-occupancy toll (HOT) lanes, and other stakeholders in policy decisions for improving HOV lane and highway mainline operations through conversion to HOT lanes.
