Evaluation of Low-Speed Profiler for Network-Level Pavement Management
For pavement management and to understand the condition of its network, Texas Department of Transportation (TxDOT) relies on high-speed inertial profilers to gather ride quality. However, a persistent challenge arises when assessing pavement smoothness at low speeds or under stop-and-go conditions (i.e., signalized intersection, stop-control intersections, high driveway density producing turning traffic, and congested roadways during peak-hour traffic) that compromises the accuracy of data collected by conventional profilers. For example, collecting ride quality measurements on a congested roadway with multiple driveways leads to acceleration and deceleration of the collection vehicle, potentially adding "false" dips into the measurements. If these dips are included in the network-level measurements, these types of roadways could receive a poor condition score that is not indicative of the true pavement condition. Collecting data on roadways with signalized intersections and slow-moving congested traffic could have the same challenges. The research team will explore the potential of low-speed profilers to enhance data collection accuracy in such scenarios. The research team will evaluate the effectiveness of low-speed profilers in providing accurate pavement profile data, particularly in areas prone to low-speed or acceleration and deceleration operations. The research team will validate the capabilities of low-speed profilers and recommend strategies for their integration into TxDOT's pavement management practices, ultimately leading to a more accurate condition assessment.
