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...
