Enforcement of high-occupancy vehicle (HOV) traffic restrictions forms an integral and sometimes critical element of HOV preferential treatment projects. This research (1) reviewed enforcement on HOV facilities, (2) identified effective HOV enforcement techniques, (3) developed model legislation for effective HOV enfoorcement and (4) prepared HOV enforcement guidelines. This report presents the findings of this research. Sixteen projects in the United States encompassing each type of freeway and arterial treatment, were visited to gain in-depth operational and enforcement data on each project.

This design guide has been developed for the purpose of helping to achieve the following transportation systems management (TSM) goals: To maximize the person-moving capacity of roadway facilities by providing improved operating level of service for high occupancy vehicles (HOVs), both public and private; To conserve fuel and to minimize consumption of other resources needed for transportation; To improve air quality; and To increase overall accessibility while reducing vehicular congestion. Part I deals with HOV options in terms of planning and operations; Part II deals with design criteria for HOV options on freeways; and Part III deals with design criteria for HOV options on surface arterial streets.
