3D Highway Alignment Optimization for Brookeville Bypass

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. This report demonstrates 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. It is expected 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.
