Collecting Stop and Go Inertial Profile Measurements

The Texas Department of Transportation (TxDOT) annually collects profile data over the state-maintained highway network. TxDOT uses the profile data to determine ride quality based on the Present Serviceability Index (PSI). The indices determined are stored in the Pavement Management Information System (PMIS) database, and are published in the PMIS reports prepared annually by the Materials and Pavements Section of the Construction Division. Inertial Reference Profilers, such as TxDOT's Profilers, are adversely affected by stop and go operations, common during PMIS data collections. When the profiler slows below 12 mph or comes to a complete stop, profile measurements are not valid. This situation causes the loss of ride data at intersections, in high traffic conditions, and in urban areas. This report describes a method that TxDOT can use that will minimize the effects of stop and go for the inertial profile measurements.
