HERS-ST: The Oregon Experience
Was It Worth It?
ODOT has found HERS-OR to be a powerful decision-support tool that can be used in program development and needs analysis as well as for establishing performance objectives. While the model has some limitations, Oregon has discovered many strong points. ODOT has learned that although HERS-OR is not a total solution to the challenge of planning, it can play a primary role in the transportation decision-making process by providing economically justified benchmarks. HERS-OR provides a solid foundation for budgetary and legislative program development and evaluation. The department sees this capability as being of increasing importance as funding constraints intensify and the public's demand for accountability increases.
In Oregon, the "what if " analysis produced by HERS-OR helped legislative bodies and other decision makers by providing a clear picture of how the condition and performance of the highway system would change under different funding scenarios. Oregon officials also found that HERS-OR could be used as a communication tool for responding to questions from the general public about the transportation system, particularly its relationship to the user. In addition, the model's underlying relationships, assumptions, and outputs have provided input to other Oregon analytical efforts.
