HERS
Highway Economic Requirements System

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:

• At the national level, the HERS model examines the relationship between investment levels and the condition and performance of the U.S. highway system
• State transportation agencies use HERS-ST for program development and needs analysis, as well as to establish performance objectives. HERS-ST has exceptionally strong capabilities to support states in planning, programming, and budgeting

Benefits of HERS

• Helps you to consider a range of trade-offs and costs not included in most pavement management systems
• Provides benefit/cost analysis on different maintenance and improvement actions so you can determine the best alternative
• Guides effective investment and maintenance decisions by forecasting future highway conditions and estimating user and agency benefits and costs

Getting the Most from HERS

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.
