The design guide has been developed for the purpose of helping to achieve the following Transportation Systems Management Goals: A. To maximize the person-moving capacity of roadway facilities by providing improved operating level of service for high occupancy vehicles, both public and private. B. To conserve fuel and to minimize consumption of other resources needed for transportation. C. To improve air quality. D. To increase overall accessibility while reducing vehicular congestion. There are available various Transportation Systems Management (TSM) tools to help achieve increased efficiency of traffic on existing transportation systems. Guidance is given for planning and design of transfer facilities and special lanes and/or preferential treatment for high occupancy vehicles.

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.
