The Ride Quality Measurement System (RQMS) operates similar to the Vehicle/Track Interaction (V/TI) Monitor, but has the advantage that it is synchronized with other measurement systems. When the RQMS is installed on a revenue vehicle with other systems, such as a Track Geometry Measurement System (TGMS), it provides invaluable insights to understand what track geometry conditions are driving undesired vehicle/track interaction conditions.
