DESIGN OF A FEASIBLE HIGHWAY ALIGNMENT THROUGH MOUNTAINOUS COUNTRY USING PROGRAM NOAH

The computer program NOAH has been developed as part of the highway optimisation program system to optimise the horizontal and vertical alignments of a new road. In the course of tests it was used to design a road passing through exceptionally mountainous terrain in the Middle East and satisfying exacting design standards. This task had proved impossible using conventional methods. It is shown in this report how, after a minor modification to the standard version of the program, it proved possible to find a road design that satisfied all the specified standards.(a) (TRRL)
