In support of the Transit Cooperative Research Program (TCRP) D-7 research program, Transportation Technology Center, Inc. (TTCI) is conducting research to develop methods for evaluating track geometry that will account for transit system vehicle performance and passenger ride quality using a combination of performance-based track geometry (PBTG) and NUCARS® modeling techniques and on-track measurements. These studies will form the basis for determining improvements in track geometry and track maintenance practices. The overall objective for the project is to demonstrate the use of PBTG techniques for improving the ride quality of transit systems. The project is being conducted with the cooperation of Dallas Area Rapid Transit (DART). The Phase 1 research determined that there is a correlation between ride quality and track geometry. Locations on the DART Red Line that had ride quality issues were identified from the ride quality test performed.
