COURSE OBJECTIVES
- To equip students with knowledge related to road system, highway engineering and traffic engineering.
- To equip students with knowledge related to highway design (geometric and pavement design) manually and using software.
COURSE LEARNING OUTCOMES (CLO)
CLO: 1. to review the traffic management plan considering traffic flow, design speed, safety, intersections needed, traffic capacity and devices/signals etc.
CLO: 2. to design flexible and rigid pavement for structural and geometric aspects.
CLO: 3. to justify and defend the recommended traffic management plan and/or geometric/pavement design.
CLO: 4. to execute the steps of geometric and pavement design using software (e.g. Eagle point, Kenpave etc.)
