Abstract:Weather-responsive management strategies (WRMS) are innovative approaches to utilizing data in making decisions for roadway operations and maintenance. Texas Department of Transportation (TxDOT) has been evaluating low-cost approaches for enhancing WRMS, with special emphasis on suburban and rural environments. The main focus of Project 0-7007 is to find a sustainable approach for automatically and passively sensing winter weather operations treatment activity through detection of plowing, sand spreading, and brine spraying, and to utilize live and historic data for spreadsheets, reports, and GIS applications. A pilot was conducted where six winter operations vehicles were equipped with sensors to detect where and when key equipment is switched on or off. General-purpose sensor inputs on the existing fleet telemetry system were then utilized to send those events through the same pipeline that supplies live-vehicle position data to TxDOT GIS apps. Successful results from the pilot, lessons learned, and findings from evaluations on fixed- and mobile-sensor devices are reported. Similar strategies are applied to events that extend beyond winter weather.
