Highway And Railroad Engineering

Overview of highway planning, classification, route surveys, and the role of highway engineering in transportation systems.

Principles of designing horizontal curves, calculating required superelevation rates, and ensuring adequate sight distances for safe vehicle operation.

Design of crest and sag vertical curves, calculating elevations, and ensuring adequate sight distance over hills and under bridges.

Design and function of highway cross-sectional elements including travel lanes, shoulders, medians, and right-of-way.

Core methodologies for collecting, analyzing, and applying traffic data to improve road networks, including volume, speed, and flow modeling.

Design, application, and legal requirements of traffic signs, pavement markings, and traffic signals to regulate, warn, and guide road users.

Principles of intersection capacity, signalization basics, conflict points, and the design of grade-separated interchanges.

Properties, classification, and testing of subgrade soils, aggregates, asphalt, and concrete used in pavement construction.

Principles of flexible pavement structure, the AASHTO 1993 design method, Structural Number (SN), and layer thickness calculations.

Structural design of Portland Cement Concrete (PCC) pavements, covering slab thickness, subbase support, and joint detailing.

Earthwork operations, equipment selection, quality control during construction, and common pavement distresses and rehabilitation strategies.

Fundamentals of the railway track structure, including rails, ties, ballast, subgrade, and the principles of track geometry.

Train resistance, required tractive effort, signaling systems, track capacity, and high-speed rail operations.

Principles of airport planning, wind rose analysis for runway orientation, and geometric design including runway length corrections.
