=== Highway engineering ===
[[File:Typical roadway cross-section sheet in transportation engineering.jpg|thumb|A [[Cross section (geometry)|typical cross-section drawing]] of a roadway.]]
{{Main article|Highway engineering|Bicycle transportation planning}}
Engineers in this specialization:
*Handle the planning, design, construction, and operation of highways, roads, and other vehicular facilities as well as their related [[cycling infrastructure|bicycle]] and pedestrian realms
*Estimate the transportation needs of the public and then secure the funding for projects
*Analyze locations of high traffic volumes and high collisions for safety and capacity
*Use engineering principles to improve the transportation system
*Utilize the three design controls, which are the drivers, the vehicles, and the roadways themselves

=== Railroad engineering ===
{{main article|Railway systems engineering}}
Railway engineers handle the design, construction, and operation of railroads and mass transit systems that use a fixed guideway (such as [[light rail]] or [[monorails]]).

Typical tasks include:

* Determine horizontal and vertical alignment of the railways
* Determine station location
* Design functional segments of stations like lines, platforms, etc.
* Estimate construction cost

Railway engineers work to build a cleaner and safer transportation network by reinvesting and revitalizing the rail system to meet future demands. In the United States, railway engineers work with elected officials in Washington, D.C., on rail transportation issues to make sure that the rail system meets the country's transportation needs.<ref>{{cite web|url=http://www.aar.org/AAR/About-Us.aspx|title=Association of American Railroads|work=AAR|access-date=2011-06-30}}</ref>

Railroad engineers can also move into the specialized field of train dispatching which focuses on train movement control.

Airport engineers design and construct airports.  Airport engineers must account for the impacts and demands of aircraft in their design of airport facilities. These engineers must use the analysis of predominant wind direction to determine runway orientation, determine the size of runway border and safety areas, different wing tip to wing tip clearances for all gates and must designate the clear zones in the entire port. The Civil Engineering Department, consisting of Civil and Structural Engineers, undertakes the structural design of passenger, terminal design and cargo terminals, aircraft hangars (for parking commercial, private and government aircraft), runways and other pavements, technical buildings for installation of airport ground aids etc. for the airports in-house requirements and consultancy projects. They are even responsible for the master plan for airports they are authorized to work with.
