Honolulu's zipper lane: a moveable barrier HOV application

As a consequence of its narrow, linear nature and its high-density land use pattern, the primary urban corridor of the city of Honolulu, Hawaii is one of the most congested in the nation. The H-1 interstate highway and several parallel major arterials serve the corridor. Among the Transportation System Management (TSM) actions implemented within the corridor over the years are a 2+ concurrent-flow HOV lane along a portion of the H-1 and several coned peak-period lanes on the arterial system. A feasibility study conducted in 1995 recommended the addition of a morning peak-period contra-flow lane paralleling the 2+ concurrent-flow lane for buses, vanpools and carpools carrying three or more persons. Safety concerns motivated the consideration of a moveable barrier system. The "Zipper Lane" was opened to traffic in the fall of 1998. This paper describes the background, design and operational characteristics of the system and, by assembling data from a variety of existing sources, provides a quick assessment of the new facility. Varying opinions about proper usage are also described.
