Expertise: Evaluation and Appraisal
Evaluation
of transport measures (including schemes, systems, strategies and policies)
forms a core part of TTR's workload. It can take place at various stages,
including initial appraisal during feasibility studies, detailed appraisal
while a measure is being designed and developed, and post-implementation evaluation
after a measure has been implemented. We also undertake longitudinal monitoring
to assess how impacts and responses change over time once a transport measure
is in operation.
Our expertise was recognised by the European Commission when we were awarded a contract to lead the MAESTRO project, which produced comprehensive guidelines for the European Commission on how to evaluate transport demonstration projects.
Evaluation can involve a range of activities in order to address different aspects of performance, as recognised within the Government NATA (New Approach to Transport Appraisal) guidelines. These aspects include:
- Behavioural impacts
- Costs
- Traffic impacts (and traffic economic efficiency)
- Wider economic impacts
- Environmental and energy impacts
- Safety impacts
- Accessibility impacts
- Equity issues
- User and stakeholder perceptions
These can be brought together within a cost-benefit or cost-effectiveness analysis or, increasingly, within an overall NATA-style appraisal framework.
