An Analysis of HOV Lanes. Edition No. 1
VDM Publishing House, Sep 2008, Pages: 100
High occupancy vehicle (HOV) lanes are freeway lanes
reserved for vehicles with more than a predetermined
number of occupants. HOV lanes can affect the
capacity of a freeway through both an
underutilization effect and a disruption effect
caused by lane-changes. This book examines the
physics of HOV lanes and their overall impact on
traffic. It uses a simple car-following model with
lane-changing that matches field data with
considerable accuracy. Current models of this type
have usually a large number of parameters, many of
them unobservable and/or with no physical meaning.
This one, in contrast, requires few parameters and is
based only on physical principles. It uses simple
microscopic rules to reproduce the aggregate
characteristics of traffic. The movement of a vehicle
is only constrained by its mechanical properties,
driver comfort, and safety. The model is used in
micro-simulations to test simple strategies for
increasing the efficiency of HOV lanes and reducing
the disruptions they cause. The results and their
implications are useful to transportation
professionals and academicians, especially those
developing new methods to improve traffic flow.
