High Occupancy Vehicle Facilities

High Occupancy Vehicle (HOV) facilities serve to increase the total number of people moved through a congested corridor by offering two kinds of travel incentives: a substantial savings in travel time, along with a reliable and predictable travel time. Because HOV lanes carry vehicles with a higher number of occupants, they move significantly more people during congested periods, even if the number of vehicles that use the HOV lane is lower than on the adjoining general purpose lanes. In general, carpoolers, vanpoolers, and bus patrons are the primary beneficiaries of HOV lanes by allowing them to move through congestion.

HOV Pooled Fund Study

The HOV Pooled Fund Study (PFS) is intended to identify and address the key issues and challenges that public agencies are facing with HOV facilities. This study provides a forum to pursue projects that address the needs that are common among participating members. Any agency or authority responsible for planning, designing, implementing, managing, and operating HOV facilities is eligible to join and participate in the PFS.
