Dynamic clustering and transport appraisal

It is increasingly important to be able to analyse and quantify how dynamic clustering (of businesses and people) can be caused by transport projects and investment, and to be able to incorporate this in the appraisal of transport projects. This is because transport projects are increasingly seen as a way to transform places, rather than solely to improve or increase transport links, and need to be appraised as such. We develop a framework for assessing (a) whether, the extent to which, and how transport interventions will trigger dynamic clustering, and (b) how to analyse this in a way that allows us to assess the economic impact of dynamic clustering (ie, on welfare and potentially also on GDP). We carry out a literature review, develop a methodology, and apply the methodology to two case studies. We have five main findings. First, the area is not only important, it is also complex and challenging. Second, practitioners should be guided by the literature, which is insightful, vast and evolving. We therefore develop high-level summaries as well as a detailed discussion of the literature. Third, there is no ‘one size fits all’ approach, and much depends on specific context. We therefore develop some practical tools that can be applied in a flexible but rigorous way. Fourth, it is critically important that analysis is carried out – rather than simply sticking to static analysis – to ensure that sound decisions are made on specific projects. But it is equally vital that analysis is carried out robustly with the strengths and potential shortcomings of such analysis being clearly articulated and recognised. This will help to advance the frontier of best practice. Fifth, there is much work in the area that still needs to be done, particularly in the quantitative analysis of key impacts. We therefore highlight potential areas for future research.
