Briefly discuss factors that are of specific importance in the location of scenic routes.
What will be an ideal response?
The following factors are of specific importance in the location of scenic routes:
? Special provisions should be provided to discourage fast driving as design
speeds are usually low (e.g. provide narrow road bed).
? Conflict between driver's attention on the road and the need to enjoy the
scenic view should be minimized. This is achieved by providing turn-outs
with wide shoulders and adequate turning space at regular intervals, or by
providing only straight alignment when the view is exceptional.
? Only minimum disruption to the area should be caused as a result of the
scenic route construction.
