The extensive planning and construction of high-occupancy vehicle (HOV) facilities during the past 20 years has resulted in more efficient freeway operations in many cities. There are, however, considerable differences among the effects of different types of HOV facilities, such as those converted from the existing lanes versus the newly constructed ones and HOV lanes versus exclusive busways. Actually, most of the newly constructed HOV facilities and conversions of busways into HOV facilities have resulted in increased vehicular capacity rather than passenger capacity of highways, which is contrary to the Intermodal Surface Transportation Efficiency Act mandate. Planning of HOV facilities, therefore, requires a careful analysis of goals as well as impacts in each particular case. Different types of HOV facilities are analyzed, principles for planning transit preferential facilities are developed, and one major problem--negative impacts of HOV facilities on bus systems--is explored. A hypothetical model based on experiences from different cities is developed and used for comparative evaluation of four cases: busways and HOV facilities obtained by conversion or addition of lanes. The present conflict between traditional urban transportation planning and the current mandated transportation systems approach is also analyzed. Relationships among policies, actions, and goals in planning HOV and busway facilities are discussed. Several revisions in the current policies and practices regarding busways and HOV facilities are recommended.
