## Description including Unit Aims

The aim of this unit is to introduce some of the concepts, models and
data that underpin transport planning decisions and the traffic
engineering profession. We will cover flavours of the following
topics:

• 1. Modern sources of travel and traffic data (e.g., inductance loops,
ANPR, bluetooth / wifi, mobile phone call records, census data etc.)
• 2. Macroscopic models for travel demand - (e.g., the gravity and
radiation models). The OD (origin-destination) matrix and the problem
of its estimation. Travel survey techniques.
• 3. Traffic assignment problem - that predicts the proportion of
different users taking different routes and modes as a function of the
travel demand and the network. The user equilibrium and system optimal
assignments and elementary examples of their computation.
• 4. Link cost models - simple examples including macroscopic
Fundamental diagram models, whole-link models, queueing models etc.
• 5. Principles of microsimulation. Car-following models and best
practice in their use.
• 6. Basics of traffic control (traffic lights etc.) and their
optimisation.

The course will also incorporate one or two seminars by external
speakers who will speak on topical points such as congestion charging
or automated vehicles.

## Intended Learning Outcomes

Upon successful completion of this unit students will be able to:

1. explain the basic principles that underpin transport planning
2. give an overview of the various sources of travel and transport data, and the ways that they can be used and misused
3. perform simple calculations that either forecast travel demand or estimate the OD matrix from observations of link flows etc
4. formulate route and mode choice as a Nash game, and compute UE and SO traffic assignments for simple network problems by hand
5. give an overview of the principles and of the simplest examples for modelling road traffic flow on a single link, for incorporation into wider network analyses
6. explain the use and potential for misuse of microscopic traffic simulation models; and be able to compute simple properties of a car-following model from its analytical formulation
7. state the basic principles of traffic signal engineering and how traffic controls might be optimised
8. give an overview of how all this theory may be used in future transport applications.
