Mobility is a basic human need.
From the times immemorial, everyone travels either for food or leisure.
A closely associated need is the transport of raw materials to a manufacturing
unit or finished goods for consumption.
Transportation fulfills these basic needs of humanity.
Transportation plays a major role in the development of the human civilization.
For instance, one could easily observe the strong correlation between the
evolution of human settlement and the proximity of transport facilities.
Also, there is a strong correlation between the quality of transport facilities
and standard of living, because of which society places a great expectation
from transportation facilities.
In other words, the solution to transportation problems must be analytically
based, economically sound, socially credible, environmentally sensitive,
practically acceptable and sustainable.
Alternatively, the transportation solution should be safe, rapid, comfortable,
convenient, economical, and eco-friendly for both men and material.
