Calibration and Confidence in Snowplow Fleet Operations and Fleet Telematics

The Indiana Department of Transportation (INDOT) spends approximately $30 to $60 million a year on deicing salt and operates fleet 1,000 winter operations trucks distributed among 140 locations. entire is now instrumented with location telematics, all new have integrated dash cameras, spreader application rate plow up/plow down into the telematics link. When storms occur, they varying regional impacts INDOT monitors several data sources including National Weather Service (NWS) live doppler, Severe Storms Laboratory’s (NSSL) Multi-Radar Multi-Sensor (MRMS) products, road weather monitoring stations, connected vehicles (CV) that provide roadway segment operating speeds. This paper discusses how has been comprehensive view conditions, truck asset locations, material distribution maps. identified widely rates for same calibration settings equipment in preliminary analysis. A box developed allow offload occur within 10 minutes without weighing or transporting vehicle. method deployed across six districts at over 1000 snowplows. sampling eight found proposed reduced average 45%. describes series dashboards managing details methods geographically units conduct simple, fast, effective calibration.
