Figure 1-7. High Occupancy Vehicle Facilities by Type and State, 2006

By reducing travel time and increasing reliability, high occupancy vehicle (HOV) lanes increase the number of people who can move through a congested corridor. While carpoolers, vanpoolers, and bus patrons benefit directly from a time-saving standpoint, we all share the benefits of cleaner air and lower energy use that are linked to HOV operations.
