Development of an high-occupancy-vehicle HOV systems manual.

This report contains both a state-of-the-art literature review of current HOV practices and guidelines and the results of an extensive survey of HOV practitioners. The literature review, the survey, and the gaps and weaknesses are presented in 10 general categories: HOV Facility Policy Considerations; Planning; Design; Marketing; Operations; Enforcement; Implementation; Support Facilities, Services, Policies and Programs; Environmental and Air Quality Impacts; and HOV Facility Evaluations and Research Needs. The report describes the development of the "HOV Systems Manual" (NCHRP Report 414).
