Choosing Safe, Cost-Effective Intersection Designs
The latest of TRB's National Cooperative Highway Research Program (NCHRP) Ready Results explores the Life-Cycle Cost Estimation Tool (LCCET), a spreadsheet-based tool for comparing the life-cycle costs of alternative designs for new and existing intersections. Designed for flexibility, the tool allows engineers to conduct analyses across different system configurations and consider a wide range of impacts. Conducting these analyses helps agencies identify locations where alternatives to traffic signals may be safer and less costly while also improving traffic flow. The tool is part of the
NCHRP Web-Only Document 220: Estimating the Life-Cycle Cost of Intersection Designs.
