The Highway Economic Requirements System (HERS) helps state departments of transportation (DOT) assess the optimal level of investment required to achieve desired highway system performance levels. By applying engineering standards to identify highway deficiencies, then assessing the impact of investments, HERS can help determine the most cost-effective mix of highway system improvements.
Two models of HERS have been developed by the Federal Highway Administration (FHWA) with assistance from Cambridge Systematics:
Cambridge Systematics has more than 12 years of experience in developing and applying HERS as a transportation planning tool. We have adapted HERS and HERS-ST for eight states, as well as for the American Association of State Highway and Transportation Officials (AASHTO). We can work with you to implement HERS effectively to maximize the value of highway improvement investments to your state.
HERS is owned by the FHWA. To request copies of HERS documents or to inquire about the program, please contact:
