Abstract

High Speed Rail Alignment Generation and Optimization using GIS
Track: Architecture, Engineering, and Construction
Authors: Roland Martin, Cary Greenwood

GIS-based analysis is used to generate, evaluate and optimize alignment alternatives for high speed rail projects across the world. This presentation will demonstrate how quick detailed analysis can save money and reduce environmental impacts.

The studies make extensive use of terrain and land use analysis along with complex geometric requirements to evaluate feasible routes and their relative costs and impacts. The information is also used to inform alignment decisions during the detailed engineering stages of the project.

The methodologies for using GIS to help design large scale engineering projects will be discussed, and the results and benefits will be demonstrated.
