The EVIDENCE Project is examining the quality of the evidence on the effects of Sustainable Urban Mobility Plans (SUMP) measures, to identify ‘what works’. SUMP measure appraisals (ex ante) can demonstrate very favourable ratios of benefits to costs when subject to the analysis techniques applied to major transport infrastructure schemes.

However, evaluation (ex post) of what are often relatively small and incremental interventions, perhaps in a context of significant local economic change, can mean those forecast effects are hard to observe in practice. Small scale often means any behavioural responses can only be detected over the long-run and after several rounds of incremental delivery, but the policy process may demand feedback more quickly in order to justify the effectiveness of the on going programme.

In this situation there is a risk that other transport investments emphasising major infrastructures are preferred, because their impacts are clearer to evaluate, even if those impacts may not be promoting the more sustainable forms of mobility.

The session will begin with brief opening statements from the panel members, followed by responses to questions. Recommendations made will be summarised in a statement of principles to enhance the future assessment of SUMP measures.

Expert Participants: The panel comprises leading international experts with many decades’ experience in examining and questioning the relevance of transport appraisal and evaluation.
