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.

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.

Learning, Teaching and Assessment (LTA) Approach:
Teaching methods for all LOs will include lectures, in-class competitions and problem solving tutorials.
Directed study tasks will encourage integration of key reading material. A Virtual Learning Environment is
utilised and all course materials including notes (Moodle workbooks), lecture and online presentations,
interactive discussions, tasks and tutorials, further reading and unit-specific quizzes can be accessed.
Embedding of employability/PDP/Scholarship Skills Module content is developed in consultation with
employers and the module contents reflect current industry practices with additional international
comparisons of codes and assessment tools. In addition to the skills of understanding the basics of
currently used assessment techniques, the ability to critique these techniques will improve students’
employability. (LO1-LO5).
Research / teaching linkages. Examples used for teaching are derived from transport research and
studies, including real project case studies and global challenges. Research and scholarly activity are
also fundamental in the studies on the module, particularly with reference to the coursework. Students are
asked to undertake scholarly activity and leverage relevant information from research publications,
academic journals and industry websites to assess current developments in Traffic Engineering. Particular
emphasis is given to the sustainability aspect of the design work that is conducted through the coursework,
as the students are asked to appraise the impact of real-life design concepts on road operations and the
users, and to identify design solutions that will optimise driving behaviour and network operations and
minimise the long-term nuisance to the local communities and environment.
Supporting equality and diversity. This module has been developed to reflect international practices in
Traffic Engineering. The module is available in FT/PT/DL formats and is accessible to all students in their
own country with no need to attend lectures in the UK or leave their current employment.

Formative Assessment:
The provision of formative feedback constitutes a key component of the LTA approach underpinning this
module. Formative feedback will arise through the discussion and analysis of the tutorial questions, inclass, and online competitions as well as through the Moodle quizzes (LO1-LO5). In addition, the
coursework component will constitute another source of formative feedback (LO1-LO3). Online and in-person
Q&A sessions in each class create an inclusive and engaging environment for the provision of formative
assessment from the instructor(s) and peers.

Summative Assessment:
The summative assessment is made up of two components, a coursework which is worth 40% of the
total module mark, and a centrally timetabled exam which is worth the remaining 60% of the mark. The
coursework will focus on the critical assessment of various implications of highway geometric design as
well as on design provisions for various groups of road users. In this context, the students will be asked to
apply what they have learned about traffic engineering design, provide design solutions for roadway
segments or intersections, and prepare a report using real-world case studies (LO1-LO3). The second
component of summative assessment is in the form of an end-of-trimester exam, testing all LOs (LO1-
