Isolated Traffic Signal Design.
Linked Traffic Signal Design - signal coordination, urban traffic control systems.
Intelligent transportation and urban traffic control systems for road network operations.

Learning Outcomes for module:

Upon completion of this module you will be able to:
LO1: Understand and critically appraise traffic flow principles, data collection techniques and road
network operations.
LO2: Identify, examine and critically assess the major design elements and principles of road layouts,
including the geometric alignment considerations based on national and international standards and
LO3: Design road intersections such as priority junctions and roundabouts and analyse road traffic
capacity, queues and delays.
LO4: Design traffic signal layouts and calculate traffic signal timings for both isolated and linked
LO5: Recommend intelligent transportation and urban traffic control systems that can provide benefits for
road network operations.
