This Innovations Deserving Exploratory Analysis (IDEA) project developed and tested a concept to determine actual track geometry alignment and cross level in sharp curves and turnouts in rail transit systems. The improved track geometry testing system would utilize the current track design or a “best fit” track design as a baseline for testing rail rapid transit and light rail transit track. This concept would provide transit systems the ability to accurately identify track geometry defects based on their track design, thereby reducing maintenance time and cost. Transit agencies could also benefit by utilizing the “best fit” track design data generated by the track geometry system as an alternative to improve their current track design.
