ROI Calculation Logic

Implementing this technology could reduce track bed lateral resistance measurement and restoration time by 2 hours per location. Assuming 5,000 measurements annually with 2 workers at ~$50/person-hour (AI est.), the estimated annual savings could be 2 hours/location × 5,000 locations × 2 workers × $50/person-hour = ~$1M (AI est.). Further cost reductions are anticipated from reduced emergency repairs due to high-precision predictive maintenance.
