Postgraduate

CEG8432 : Transport Modelling and Traffic Flow

Semesters
Semester 1 Credit Value: 20
ECTS Credits: 10.0

Aims

This module intends to cover
•       the techniques used by transport planners for modelling transport systems across the scales and the theory underlying them and the relevant themes in the context of the Four-step planning model
•       the application of theory related to transport modelling as well as hands on experience of software packages play a major role when it comes to decision-making in transport planning and policy evaluation, and
•       the basic principles of traffic flow and control, capacity and congestion. It will include development of signal control far beyond the current course content
•       how traffic flows can be managed and controlled to address air quality with particular attention to reduce emissions

Outline Of Syllabus

WEEK 1
Traffic flow theory (RNB)
•       Traffic Flow Theory (SMS, TMS, Headway, Spacing, flow, density) Speed / flow / density curves, shockwaves
•       Develop understanding how the junction turning movement flows and built environment govern the need for design of a priority or a roundabout or isolated signal control junction. Designing for signal co-ordination.

Signal Control, Pollution Monitoring and Air Quality Management (MCB)
•       Basics of fixed time area signal control; defining traffic signal plans; plan change methods; limitations of fixed time area signal control; ageing of traffic signal plans; fundamentals of demand responsive control;
•       Introduction to pollution measurement using precision and low cost pervasive monitoring systems.
•       Integration of data available as a by-product of intelligent transport systems, to improve the performance and assessment of networks.
•       Environment modelling in an Integrated Database.
•       Case studies of tactical and strategic traffic management and control to address poor air quality.

Traffic simulation (PG):
•       Basics of traffic microsimulation; Stochastic versus deterministic simulations – random seeds and runs; Vehicle kinematics and Euler equations – time step approach; Principles of car following, lane changing and gap acceptance; Inputs to microsimulation; Outputs from microsimulation – types of output, processing and determination of number of runs
•       Applications of microsimulation: Junction capacity examples: Priority versus roundabouts and signal control in VISSIM
•       Environmental parameters calculated via microsimulation: greenhouse gases, noise and air pollution: Worked example using gating strategies in VISSIM


WEEK 2
4-Step Transport Planning Model (DD):
•       Travel demand forecasting process,
•       the Four-step transportation planning model;
•       Trip-end forecasting (The lectures followed by computer practical and in-class tutorials)
•       Trip distribution forecasting (The lectures and in-class tutorials)
•       Mode choice forecasting (The lectures and in-class tutorials)
•       Traffic assignment (The lectures followed by computer practical and in-class tutorials)

Teaching Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

Teaching Rationale And Relationship

Specialist knowledge, understanding and skills are primarily imparted via lectures. Students carry out travel planning activities to reinforce these skills. In addition to the formal lectures, field visits, workshops and several guest lectures will be included to cover the practical implementation of transport plans.

Alternatives will be offered to students unable to be present-in-person due to the prevailing C-19 circumstances.
Student’s should consult their individual timetable for up-to-date delivery information.

Assessment Methods

Assessment Rationale And Relationship

This module is assessed by written examination and coursework. The examination tests students' knowledge and understanding of underlying issues in the module through written communication. The coursework (a report on Travel Plan Activity) examines the students' decision making skills using a real-world case study.
