COURSE PROVIDER: Gilbert Gedeon, P.E.
Impact of Exempt Vehicles on HOV Lanes
Course Highlights

This online engineering PDH course presents information on defining high-occupancy vehicle (HOV) lane capacity, options for using available HOV lane capacity, and analyzing HOV exemption policies. It examines the potential impact of certain exempt vehicles on the operation of high-occupancy vehicles (HOV) facilities. The possible exempt vehicles examined in this course include environmentally friendly vehicles, and law enforcement, emergency services, and designated public transportation vehicles. It also presents the experience with the use of HOV lanes by these types of exempt vehicles. Finally, it examines the potential issues and approaches for allowing exempt vehicles to use HOV lanes.


Traffic congestion continues to be a major issue in metropolitan areas throughout the country. The agencies responsible for the surface transportation system in these regions use a variety of approaches and techniques to address concerns relating to traffic congestion, mobility, and air quality. The use of HOV facilities represents one approach in use or being considered in many urban areas.


This 5 PDH online course is applicable to traffic engineers, transportation planners, conceptual and detail designers, and other technical professionals who will be considering HOV exemption policies as well as monitoring and evaluating the use of HOV lanes by exempt vehicles.
