The purpose of this award to south dakota department of transportation are the port of entry WIM renovation; unified carrier registration verification; and the commercial vehicle wind warnings projects

The Federal Motor Carrier Safety Administration awarded the South Dakota Department of Transportation $825,254 on December 1, 2025, under the Motor Carrier Safety Assistance High Priority Activities Grants and Cooperative Agreements program (CFDA 20.237) to fund three commercial vehicle safety projects with a period of performance through September 30, 2030.

The award funds procurement, deployment, and operation of weigh-in-motion systems and load cells at two port-of-entry locations; modification of the state's IRP/IFTA system software and registration workflow to automate Unified Carrier Registration verification and maintain records with timely filing; and development and deployment of a wind warning system to prevent wind-related commercial vehicle rollovers. The wind warning system will ingest wind speed, gust, and direction data from the National Weather Service and the South Dakota Department of Transportation's road and weather information systems, analyze wind conditions relative to state highway network segment alignment using industry-standard truck type definitions, generate wind warning and closure advisories, and present real-time advisories through SD511 products including website, mobile apps, interactive voice response, and push notifications. The system will also generate a GeoJSON data feed updated every five minutes for third-party providers and in-cab commercial vehicle applications, with documentation in industry-standard Swagger format. Work is performed in South Dakota.

Project 1 objective: procure, deploy and operate weigh in motion (WIM) and load cells at 2 locations. Project 2 objective: south dakota?s IRP/ifta system vendor will modify the system software and the registration workflow to automate UCR and signature of the agreement to maintain records and timely filing.

The system will: ingest wind speed, gust and direction data from the national weather service (NWS) and sdot?s road/weather information systems (rwis) sites; use industry-standard definitions for truck types; analyze wind speed, gust and direction data relative to alignment of segments on the state highway network; generate wind warning and closure advisories from wind, roadway and truck data; present real-time wind warning and closure advisories on SD511 products, including website, mobile apps, interactive voice response and ?push? Notifications; generate a geojson data feed for third party providers, including in-CAB applications for commercial vehicles, every 5 minutes; document the data feed in industry-standard swagger format.
