Most state departments of transportation have at least five major transportation engineering sub-classes. Five of these subspecialties in the Virginia Department of Transportation are the planning division, location and design division, maintenance division, traffic engineering division, and a construction division. The planning division is primarily concerned developing long-range transportation plans. This is accomplished by first defining transportation needs, gathering and analyzing data, and then evaluating alternatives.
The location and design division is primarily concerned with designing the transportation system. Usually with the design of highways, this division is responsible for the selection of dimensions for all geometric features, which include the longitudinal profiles, vertical curves and elevations, and right-of-way.
The maintenance division is responsible for maintaining the transportation system to ensure it is in proper working order. This includes repairing damaged roadway sections and the scheduling of maintenance operations.
The traffic engineering division is responsible for the integration of the vehicles, drivers, and pedestrians into the transportation system in a manner that improves the safety and capacity of streets and highways. This includes analyzing traffic accidents, design of parking areas, and the design of roadway traffic signing plans.
The construction division is another subspecialty. This division is responsible for the building of the facilities designed by the location and design division. The primary tasks of this division include the development of contracts for highway construction, inspection of highway construction projects as
performed by contractors, and publishing of manuals such as road and bridge specifications.
