Highway Economic Requirements System - v. IV. Technical Report (Version 3.26)

The Highway Economic Requirements System (HERS) is a computer model designed to simulate improvement selection decisions based on the relative benefit-cost merits of alternative improvement options. HERS is intended to estimate national level investment requirements which assume state highway improvement selection decisions that consider the relationship between benefits accruing to highway users and agencies, ant the initial improvement cost of a potential improvement option. Output from the HERS model is used in preparation of the Department of Transportation's (DOT) biennial Status of the Nation's Highway and Transit Systems Report: Conditions and Performance Report (CandP Report) to Congress. The HERS model is the result of the efforts to better examine costs, benefits and national economic implications association with highway investment options.\n
