Computer-Aided Forest Road Design. Edition No. 1
VDM Publishing House, May 2009, Pages: 156
A 3D forest road alignment model, aided by an
interactive computer system, was developed to design
a path with the lowest total construction,
maintenance, and transportation costs, while
conforming to design specifications, environmental
requirements, and driver safety. The contributions
of the model are: enhancing data input and user
efficiency through a 3D graphic interface and
automated horizontal and vertical curve fitting
routines, cross section generation, and cost
routines for construction, maintenance, and vehicle
use; ensuring road feasibility by considering
terrain conditions, geometric specifications, and
driver safety; enhancing economic efficiency by
combining modern optimization techniques to minimize
earthwork allocation cost and to optimize vertical
alignment; and considering environmental impacts by
estimating the sediment delivered to a stream from
the road section. The first chapter of the book
synthesizes the methods that are available for road
design and construction. The second chapter covers
the methodology behind the model. The last chapter
presents the features of the model and its
application.
