Limited capital investment for major transportation improvements and growth in metropolitan areas require the most efficient use of the existing transportation system. Provisions of the Clean Air Act Amendments and TEA-21 further intensity these concerns. One means to improve mobility is high-occupancy vehicle (HOV) lanes. HOV lanes have been shown to be very successful in Texas, however, they have been met with skepticism in several areas across the country. While some of the claims against HOV lanes may be justified, a need exists to evaluate new HOV lanes implemented in the Dallas areas as well as to continue an evaluation of existing HOV lanes. The objective of this research is to investigate the operational effectiveness of the Dallas area HOV lanes. Issues such as person movement, carpool formation, travel tie savings, violation rates, safety, and project cost effectiveness are addressed. By understanding the operational performance and issues of both concurrent flow (buffer-separated) and contraflow (barrier-separated) HOV lanes, recommendations can be made on suggested HOV lane policies to be implemented in the Dallas area.
