Potential Impact of Exempt Vehicles on HOV Lanes
Vincent D. Reynolds, MBA, P.E.
HOV lanes provide
for better flow of traffic on our roadways. This course will provide information
regarding the impact of several exempt vehicles on HOV lanes. The course materials
are based solely on the technical report "Potential Impact of Exempt Vehicles
on HOV Lanes" as found on the website of the Federal Highway Administration
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
At the conclusion of this course, the student would have learned the following:
Intended Audience and Benefit
This course is
intended for anyone with an interest in HOV lanes, traffic engineering transportation
engineering, air pollution, environmental engineering or anyone wanting to know
a brief history of HOV lanes and how they operate. After reading this course
the student will know which exempt vehicles can be operated in the HOV lane
with only one occupant. This information may be essential to future vehicles
purchases by the reader.
To relive traffic
congestion traffic engineers must always rely on sound engineering judgment
and methods to make traffic flow more efficiently. The drive in a metropolitan
area will almost be exposed to HOV lanes. In most states and unless permission
is given, single occupancy vehicles are not permitted to operate in the HOV
lanes. There are however exempt vehicles that can freely use the HOV lanes.
This course will explore which vehicles are exempt and how they impact the HOV
This course will provide information regarding the impact of several exempt vehicles on HOV lanes. The course materials are based solely on the technical report "Potential Impact of Exempt Vehicles on HOV Lanes" as found on the website of the Federal Highway Administration (FHWA).

presented in this course could be used to enhance our knowledge about how exempt
vehicles impact HOV lanes. Using this knowledge could speed up travel time;
minimize the number of vehicles on the highways and most importantly save our
environment. As always good judgment and good engineering judgment is always
paramount in any situation. Utilizing good judgment and the knowledge gained
in this course can provide much more efficient highways.
