Transport engineering is the study of principles to the planning, operation and management for any mode of transportation to provide compatible movement of people and goods.Planning transport engineering involves urban planning. Forecasting traffic involves a computer model, requiring the estimation of trip generation, mode choice and route assignment.
Transportation engineering mainly involves planning, design, construction, maintenance and operation of transportation facilities. The facilities support air, highway, railroad pipeline, water and space transportation. The design aspect of transport engineering includes the sizing of transportation facilities, determining the materials and thickness used in pavement designing the geometry of the roadway.
