Give the importance of road with regards to topographic factors.
Answers
Answer:
Topography Factors Second important factor that affects the geometric design is the topography. For a plain terrain, it is very easy to construct the highway as per the standards. As the terrain and the gradient increases the construction cost will increase for a specific design speed.
Explanation:
The growing importance of road transport is rooted in the following reasons:
(a) The construction cost of roads is much lower than that of railway lines,
(b) roads can traverse comparatively more dissected and undulating topography,
(c) roads can negotiate higher gradients of slopes and as such can traverse mountains such as the Himalayas,
(d) road transport is economical in the transportation of a few persons and relatively smaller amount of goods over short distances,
(e) it also provides door-to-door service, thus the cost of loading and unloading is much lower,
(f) road transport is also used as a feeder to other modes of transport such as they provide a link between railway stations, air and sea ports.
