Generating Weather Alerts Including High Wind Blowover Hazards Using Pikalert® for the Wyoming Connected Vehicle Pilot Project

The 402-mile corridor on Interstate 80 through southern Wyoming was selected in September 2015 as one of three projects for the U.S. Department of Transportation’s Connected Vehicle (CV) Pilot Deployment Project. The Wyoming CV Pilot site is an important freight corridor that experiences frequent and severe weather including snow and ice conditions, blowing snow, and high winds. Winds over 30 miles per hour are common on the corridor, causing frequent blowover crashes, particularly for high profile freight vehicles. As part of the Wyoming CV Pilot, the Pikalert ® System is being integrated into the Wyoming Department of Transportation’s Traffic Management Center backoffice systems to improve the quality and timeliness of actionable weather information for travelers on the corridor. Weather alerts include precipitation, pavement condition, visibility, and blowover hazard information for each one-mile segment of the corridor for current conditions as well as hourly road condition forecasts for one to 72 hours. The focus of this paper is to give an overview of how the Pikalert system is being utilized in the Wyoming CV Pilot and to provide details on the new Blowover Risk Algorithm that was developed for the Pilot.
