Major Investment, Corridor and Value Engineering Support

Project Description

The System Operation Management program has assisted the Dallas, Fort Worth and El Paso Districts with planning of roadway and transit improvements in numerous freeway corridors. This support has occurred as TTI staff participated on technical and executive level advisory work groups for major investment, corridor and value engineering studies. One innovative way TTI has supported these groups is with a spreadsheet tool known as the System Plan. The System Plan is a transportation corridor and system analysis tool that bridges the gap between regional planning and detailed corridor design. It allows for the examination of peak hour person movement for different facility types (e.g., general purpose versus high-occupancy vehicle lanes) within a corridor and estimates associated public costs such as right-of-way, construction, operation, congestion, and environmental costs). The objective of the System Plan methodology is to find the lowest total public cost alternative.
