Experience: Evaluation and Appraisal

The following are selected examples of evaluation work TTR has undertaken.

Behavioural impacts

Evaluated the modal 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.

Costs

Developed and applied life cycle cost models for potential road user charging or workplace parking levy schemes in Belfast, Leeds and Nottingham.
Produced cost estimates for traffic management and control measures and for new vehicle technologies such as kneeling buses and alternative fuelled vehicles.

Traffic impacts

Used models to evaluate traffic impacts of potential wide area charging schemes in the south of England.
Evaluated journey time impacts of a local scheme including bus lanes and signal priority measures on the A57 in Liverpool.

Wider economic impacts

Researched the impacts on local traders of pedestrianisation and schemes that restrict car access, for the Department for Transport (DfT).
Studied the likely impacts of a demand management scheme in central Bristol on the city centre economy.

Environmental and energy impacts

Within the Merseyside JUPITER project, developed and used the JET emission and energy consumption model to evaluate a package that included clean fuel vehicles and a number of modal shift measures.
Worked under the DfT TRAMAQ programme to take network-based emission model development further and link into air quality models.

Safety impacts

Examined issues of potential conflict between motorised wheelchairs and pedestrians for DfT, in order to feed future policy.
Participated in the European project that developed the COMMUTE strategic assessment model that includes multi-modal safety impacts.

Accessibility impacts

Developed an accessibility model for Dorset County Council for assessing the range of facilities accessible by public transport from different locations.
Undertook a study of accessibility to post-16 education facilities for young people in Torbay.

Equity issues

Carried out a study for Fife Council of equity issues related to road user charging proposals being developed by the City of Edinburgh.

User and stakeholder perceptions

Conducted focus groups and a web-based survey to establish perceptions of the Nottingham Travelwise centre.
Researched attitudes towards the Traveline phone-based travel information service and the new Transport Direct web-based service for DfT.
