Toll roads, bridges and tunnels represent the most popular class of infrastructure attracting international private finance today. Many deals, however, expose financiers, insurers and other project counterparties to demand risk. This moves traffic and revenue forecasts centre-stage in terms of being able to understand and test the investment proposition - yet the forecasting process itself often remains a mystery. Additionally, there are frequent concerns about predictive reliability. Written specifically for credit analysts, investors and other professionals whose primary expertise lies outside transportation, this book lifts the lid on the 'black box' of traffic and revenue forecasting. The author, Robert Bain (ex-S&P and a civil engineer with 20+ years of forecasting experience) has prepared a straightforward guide which highlights key issues to watch for and suggests ways in which the forecasts can be analysed to improve transparency and investor understanding.
