lane financial feasibility and acceptability will continue to depend on many factors including the local perceptions of equity and the proportion of costs that likely would be covered by potential value pricing revenues. All of this means that a ground swell of rapid shifts from straight HOV facilities to other operat- ing arrangements is not likely to be seen. Rather what is most likely is a gradual, opportunistic, and deliberate evolution where each proposal for enhancement or change is examined very care- fully over an extended period of time before selected projects go forward (Bhatt, 2003). The chal- lenge for transportation professionals and policy makers will continue to be to match appropriate strategies to local issues and opportunities. Those tasked with projecting and interpreting the potential changes in travel behavior and other effects associated with different types of approaches will want to utilize not only information such as that provided in this "HOV Facilities" Handbook chapter and the selected underlying and additional sources it identifies, but also other chapters (and related sources) including Chapter 14, "Road Value Pricing"; Chapter 4, "Busways, BRT and Express Bus"; Chapter 3, "Park-and-Ride/Pool"; and the various chapters addressing TDM actions. Beyond that, many evaluations will deserve in depth demand-model-based analysis of site-specific travel patterns and impacts as individual proposals progress into detailed evaluations and design. ADDITIONAL RESOURCES The NCHRP Report 414, "HOV Systems Manual" (Texas Transportation Institute, Parsons Brinckerhoff, and Pacific Rim Resources, 1998) provides a comprehensive overview of policy development, planning, designing, marketing, implementation, operation, enforcement and eval- uation for HOV facilities. HOT lane development guidance is offered in the FHWA document, "A Guide for HOT Lane Development" (Perez and Sciara, 2003). The Texas Transportation Institute report, A Description of High Occupancy Vehicle Facilities in North America (Turnbull and Hanks, 1990), also published by the U.S. Department of Transportation Technology Sharing Reprint Series, provides a compilation of characteristics as of 1989 for U.S. and Canadian HOV facilities in freeways and separate rights-of-way. Periodically updated inventories of HOV facilities including HOT and other managed lane installations are now available on the Web but, at present, contain little or no volume or travel demand informa- tion. The FHWA Office of Operations "High Occupancy Vehicle (HOV) Facilities" WebPages ( provide various resources including a look-up inventory of facilities (Federal Highway Administration, 2005a) and a recent- year overall inventory of freeway and expressway HOV/HOT facilities in North America. This website also provides a link to the FHWA "HOV Pooled Fund Study" (PFS) Website (http://hov with its information and handbooks sponsored by PFS partici- pating agencies. The Transportation Research Board (TRB) HOV Systems Committee Website (, in addition to offering committee and HOV project information and news, links to the McCormick Rankin Website (, home of the TRB HOV Systems Committee's "Worldwide Arterial HOV Lane Database" cover- ing North America, Australia, Europe, and other parts of the world. Each of these inventories includes physical and operating characteristics and rules. A detailed yet broad-based current and historical assessment of the Houston and Dallas HOV sys- tems, with nationally applicable observations, is available in the Texas Transportation Institute report, An Evaluation of High-Occupancy Vehicle Lanes in Texas, 1996 (Stockton et al., 1997).
