Transportation planning deals with the generation and distribution of activity along a road network. A safe, convenient and efficient movement of goods and people requires an integration of engineering, economic, environmental, political and social aspects and an optimal allocation of these activities needs to be carefully planned. Even when geotechnical aspects cause a constraint it is possible to plan a route which optimally utilises the land. Remote sensing data acquired from airbourne space platforms and engineering surveys have offered the planner a complete picture of the land and helped to identify the location and quantity of activity from method of the Moments/Trip polygon method and the allocation technique. Cost modelling technique has been used to identify the optimum route for the user, system, non-user, government and region point of view.
