Module summary

The module is designed to develop specialist skills required by transport engineers. In particular traffic signal engineers require an understanding of the concepts of saturation flow, how the queues build up and dissipate at junctions and the principles involved in designing signalised junctions. Transport engineers also require advanced understanding of the principles and methods to design complex intersections. The module is divided into two halves as such dealing with traffic signals and geometrical design of complex junctions.

Objectives

To ensure that students are equipped with the theoretical understanding and practical skills needed for the design of safe and efficient highway links and junctions (including signalised), and that they understand the advantages and disadvantages of different solutions and their appropriateness in different circumstances in the UK and elsewhere.

To ensure that students have a sound understanding of the principles of traffic signal control as applied in the UK and elsewhere, and that they understand how it interacts with other control and advice systems. To ensure that they understand the behaviour of traffic in response to signals and the techniques used to model that behaviour.

Learning outcomes
Upon successful completion, students will understand the theory underpinning the design of: highway links; priority junctions; roundabouts; signalised junctions. They will have an understanding of the SCOOT system.

Skills outcomes
- Data analysis software experience/ skills.
- Drawing and sketching skills.
- Numerical competence.
- Understanding driver behaviour.

Syllabus

Link design: road capacity, horizontal alignment, vertical alignment, overtaking areas, climbing lanes.
Junction Design: priority junctions, roundabouts, Multi-level intersections, high speed weaving areas.
Principles of traffic control: saturation flow measurement and estimation; pcu values; delays at isolated junctions; Webster's method for optimising timings; multiple conflicts including early cut-off, late start; signal controlled pedestrian crossings; vehicle and pedestrian detectors; co-ordinated network control principles; current UTMC systems; signalised roundabouts; SCOOT.

Private study

The students will be expected to read a number of key texts and papers to underpin their knowledge.
The course assessment will involve a coursework based on the design of a signalised roundabout , plus an exam.

Opportunities for Formative Feedback

Feedback given through interaction during lectures and through performance in coursework.
