The Status of the Nation’s Highways, Bridges, and Transit: Conditions and Performance Report to Congress (C&P Report) is a biennial report dating back to 1968—to satisfy reporting required by 23 United States Code (U.S.C.) §503(b)(8) and transit systems required by 49 U.S.C. §308(e), beginning in 1993. The report provides decision makers with an objective appraisal of the physical conditions, operational performance, and financing mechanisms of highways, bridges, and transit systems based on both their current states and their projected future states. The highway future investment scenarios developed for this report are based on the Highway Economic Requirement System (HERS) and the National Bridge Investment Analysis System (NBIAS). Both HERS and NBIAS are used to estimate future investment needs based on current pavement and bridge conditions, respectively, and/or estimate future conditions based on known investment levels. The HERS model also includes current and future traffic volumes to estimate future system expansion needs. Both models use benefit-cost analysis to select projects for improvement. The Transit Economic Requirements Model performs a similar function for transit systems. Starting with the 24th edition, an interactive dashboard is available to facilitate exploration of the data underlying a handful of exhibits presented in the report.
