By the time you've finished this course, you'll have the ability to:

• interpret basic traffic measurements to calculate speed flow and density
• select and design appropriate traffic management systems
• calculate basic timings for an isolated signal installation
• design a coordinated signal installation
• estimate emissions from SCOOT algorithms

Course Outline

• Basis of traffic flow theory (e.g. speed flow curve, link capacity, principles of link design).
• Capacity of roads and transport systems - what is capacity?.
• Traffic Management as an alternative to new road building and widening.
• Junction design (e.g. different types, route and network capacity governed by critical junctions).
• Signal-controlled junctions (e.g. isolated signal design calculations, Webster and Cobbe).
• Signal plans (e.g. for different times of the day).
• Worked examples and computer design - on-street data collection or using video in class.
• Green waves, maximum band widths, area-based coordination.
• Principles of TRANSYT (e.g. models, dispersion algorithm, concepts of performance, measures (uniform and random (half isolated)) of delay, stops, queue component, emissions, use of PI to optimise network, hill climbing process).
• Signal plans for time of day, special events, weather, plan change algorithms, ageing of traffic signal plans.
• Pedestrian crossings, pelicans, toucans, pv^2.
• Limitations of fixed time control, 2.5 generation plans, demand responsive control.
• Bus TRANSYT and principles of SCOOT, Message types, signal timing protocols, accommodating bus priority.
• Data integration and systems architecture for traffic control and management - public and operator interfaces (Site Visit - UTMC).
• Emissions estimation - vehicle and systems, from "average flow, average speed" to bespoke SCOOT based emissions algorithms; behavioural effect on emissions.
