This paper reviews methods that seek to draw causal inference from non-experimental data and shows how they can be applied to undertake ex-post evaluation of transport interventions. In particular, the paper discusses the underlying principles of techniques for treatment effect estimation with...

Mobility as a Service (MaaS) is widely expected to make sustainable transport choices more attractive. New approaches to ticketing will be a core part of MaaS, both to attract users and fund services. The associated pricing decisions will be a matter of public policy as much as business...

The case for including agglomeration benefits within transport appraisal rests on an assumed causality between access to economic mass and productivity. Such causality is difficult to establish empirically because estimates may be subject to sources of bias from endogeneity and confounding. They...
