Road Network Operations – introduction to traffic flow, user characteristics, data collection, forecasting,
and capacity.
HighwayGeometric Design Considerations – highway link design, including design speed, crosssections, sight, and overtaking distances.
Highway Geometric Alignment Design – design of horizontal and vertical road alignment.
Intersections – general junction design principles and analysis of priority junctions.
Roundabouts – types of roundabouts, layout design and capacity analysis.
Introduction to Traffic Signal Control – principles of traffic signal control including
saturation flows, stages, phases, cycle times and green times.
Basic Isolated Traffic Signal Design – design of layouts and calculation of signal timings. Advanced
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.

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
guidelines.
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
networks.
LO5: Recommend intelligent transportation and urban traffic control systems that can provide benefits for
road network operations.
