• Abstract:
  This study applies the previously developed Highway Alignment Optimization (HAO) ; model to the MD 97 Bypass project in Brookeville, Maryland. The objective of this study is to ; demonstrate the applicability of the HAO model to a real highway project with due consideration ; to issues arising in real world applications. In this report, we demonstrate the sensitivity of ; optimized alignments to various user-specified input variables, such as the number of points of ; intersection (PI’s), tradeoff values for the environmental sensitive areas, grid size for elevation, ; design speed, and cross-section spacing. We expect that the optimized results from the HAO ; model will be compared with those obtained through conventional manual methods by the ; Maryland State Highway Administration (SHA). In addition, this report should be helpful in ; familiarizing readers with the nature and capabilities of the HAO model.
