PRIORITY TREATMENT FOR HIGH OCCUPANCY VEHICLES IN THE UNITED STATES: A REVIEW OF RECENT AND FORTHCOMING PROJECTS

The purposes of the report are to: (1) describe recent High Occupancy Vehicle (HOV) preferential projects in the United States; (2) summarize the results of these projects and draw implications; and (3) outline projects which are to be implemented over the next few years. The report describes each of the following approaches to preferential treatment: non-separated concurrent-flow freeway HOV lanes; contra-flow freeway lanes; metered-ramp bypass lanes and exclusive ramps; physically separated priority lanes; express bus service and park-and-ride lots; lanes on arterials and Central Business District (CBD) streets reserved for buses; bus priority signal systems on arterials and CBD streets; transit malls; and auto restricted zones. During the late 1960's and early 1970's, a variety of priority treatments were attempted. Both capital intensive projects and non-capital intensive projects were implemented during this period. By the middle of the 1970's, thinking within the transportation planning community had moved away from the costly capital intensive priority treatments that require extensive new construction to the more operationally oriented traffic management schemes that use existing facilities in a more efficient manner. Except for the non-separated concurrent flow projects, other non-capital intensive priority treatments on freeways have fared well. Nearly every HOV priority treatment on freeways has involved the use of new or expanded express bus service and the opening of new park-and-ride lots. Arterial and CBD street bus lanes have been implemented in many cities, transit malls have grown in popularity, and four auto restricted zones are to be built during the next few years.
