| 摘要： | The Highway Economic Requirements System-State Version (HERS-ST) is a software package that estimates the investment that would be required to achieve certain highway system performance levels. Alternatively, the software can be used to estimate the highway system performance that would result given various investment levels. HERS-ST considers capital improvement projects directed at correcting pavement and capacity deficiencies. The HERS-ST model is a direct extension of the national-level HERS model. This model was developed by the Federal Highway Administration (FHWA) to examine the relationship between national investment levels and the condition and performance of the Nation's highways. FHWA uses the model to estimate future highway investment requirements under different scenarios. FHWA provides this information to the U.S. Congress in the biennial Status of the Nation's Highways, Bridges and Transit: Conditions and Performance Report to Congress. The HERS-ST model includes not only the analytical engines which comprise the national model but also a graphical user interface (GUI) module. The GUI environment includes tools for organizing the HERS-ST workspace, performance the HERS analysis, and organizing and formatting program output. |
