Details

We wanted to understand how and why transport schemes achieve transformational impacts and how contextual factors, such as local conditions, complementary investments and policies, can work with a new transport investment.

The work involved:

  • a literature review to better understand the current evidence and potential contextual factors that may interact with schemes

  • 15 case studies on rail and road schemes to provide insights into how the context surrounding a scheme may have affected whether it was transformational, based on indicators such as patronage, productivity, employment, population growth and housing

  • qualitative comparative analysis (QCA) to identify a series of necessary and/or sufficient conditions that determine whether a scheme is ultimately transformational or not

  • an in-depth case study of the West Coast Mainline upgrades, extending findings with econometric analysis to attribute economic and demographic impacts to transport investment
