shift impact of dynamic environmental information (using VMS), real time
bus information, and road user charging trials in Bristol.
- Researched the behavioural
impacts of increased roadside camera law enforcement and of future automated
highway systems for the Highways Agency.

life cycle cost models for potential road user charging or workplace parking
levy schemes in Belfast, Leeds and Nottingham.

traffic impacts of potential wide area charging schemes in the south of

- Worked under the DfT
TRAMAQ programme to take network-based emission model development further
and link into air quality models.
- Examined issues of
potential conflict between motorised wheelchairs and pedestrians for DfT,
in order to feed future policy.
