Transportation

Roads, rails, runways and the traffic that uses them. Planning and designing transport infrastructure: highway geometric design, railway track and alignment, airport runways, traffic flow and signal design, and flexible and rigid pavement design — the systems that move people and goods safely.

• Highway Engineering — Highway engineering designs safe, efficient roads. Learn road classification, design speed, sight distances (stopping, overtaking), horizontal curves and superelevation, transition curves, vertical curves, cross-section elements and drainage.
• Railway Engineering — Railway engineering covers track, alignment and operations. Learn track components (rails, sleepers, ballast, fastenings), gauges, curves and cant, cant deficiency, gradients and train resistance, adhesion, points and crossings, and high-speed rail.
• Airport Engineering — Airport engineering plans and designs airfields. Learn site selection, runway orientation and wind coverage, runway length corrections (elevation, temperature, gradient), taxiways and aprons, airfield pavements, obstacle limitation surfaces and terminal planning.
• Traffic Engineering — Traffic engineering studies how vehicles and people move and how to control them. Learn traffic stream parameters (flow, speed, density), the fundamental diagram, capacity and level of service, traffic studies, intersection control and signal timing (Webster), and ITS.
• Pavement Design — Pavements spread wheel loads to the subgrade. Learn flexible vs rigid pavements, layers and materials, subgrade CBR, traffic in standard axles (ESAL/msa) and the fourth-power law, empirical and mechanistic-empirical design, and distress and maintenance.
