In the US transportation P3 sector, traffic forecasters have historically been asked to model the demand for tolled, greenfield bridge or highway investments. That is because historically, new greenfield megaprojects have been the vast majority of projects that public sponsors have been considering funding via user fees.
Increasingly, however, more public sponsors have considered, and asked their consultants to forecast, a very different question: how would drivers respond if tolling is applied to an existing bridge, tunnel or roadway asset?
That question is the subject of a new report and international dataset containing 76 such cases, in which new tolls were activated, or deactivated, on a brownfield transportation asset. The dataset and report were compiled by the CSRB Group, a specialist due diligence consulting firm for road and rail investments, with corresponding author Robert Bain. A copy of the report is available here.
