WYOMING DOT Connected Vehicle Pilot
Improving safety and travel reliability on I-80 in Wyoming

Interstate 80 (I-80) runs 402 miles along Wyoming’s southern border and is an essential east-west connector for freight and passenger travel. The corridor averages more than 32 million tons of freight deliveries each year.

A lack of alternate routes means truck volume can reach as much as 70 percent during seasonal peaks.

Wyoming’s extreme weather—including blowing snow in winter and fog and high winds in summer—create dangerous conditions for drivers on I-80.

WYDOT is doing something about it.

In 2015, the U.S. Department of Transportation (USDOT) selected Wyoming as one of three locations to test and deploy advanced dedicated short-range communication (DSRC) technology to improve safety and mobility.

In the Connected Vehicle Pilot (CVP), WYDOT will use vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and infrastructure-to-vehicle (I2V) connectivity to improve monitoring and reporting of road conditions to vehicles on I-80.

Winding road icon with the number 75

Receive and broadcast messages using DSRC technology along sections of I-80. The units will be installed at locations along the corridor based on identified hotspots.

Vehicle icon with the number 400

Equipped with DSRC-connected onboard units that broadcast basic safety messages, share alerts and advisories, and collect environmental data through mobile weather sensors.

Cellular phone with the number 511

The data collected by fleets and roadside units gives drivers in Wyoming improved travel information through services like the Wyoming 511 app and the commercial vehicle operator portal (CVOP).

The V2V, V2I, and I2V applications developed by WYDOT will support a flexible range of services. Information from these applications will be made available directly to fleets participating in the pilot or through WYDOT’s traveler information resources.

Pin, road, and exclamation point icon, used to illustrate forward collision warning 


Issues an alert if there is a threat of front-end collision with another connected vehicle in their travel lane and direction. Forward collision warning will help drivers avoid or reduce the severity of front-to-rear vehicle collisions. The system does not take control of the vehicle to avoid a collision.

I2V Situational Awareness

Provides relevant road condition information including weather alerts, speed restrictions, vehicle restrictions, road conditions, incidents, parking, and road closures. The information is broadcast from roadside units and received by the connected vehicle.

Work Zone Warning

Communicates information to approaching vehicles about conditions at a work zone ahead. Approaching vehicles receive information about work zone activities or restriction information that could present unsafe conditions, such as obstructions in a vehicle’s travel lane, lane closures, lane shifts, speed reductions, or vehicles entering or exiting the work zone.

Spot Weather Impact Warning

Enables localized road condition information, such as fog or icy roads, to be broadcast from a roadside unit and received by a connected vehicle.

Distress Notification

Allows connected vehicles to communicate a distress status when the vehicle’s sensors detect something that might require assistance from others. Distress status can also be activated manually.

Sponsored by the USDOT Intelligent Transportation Systems Joint Program Office, the Connected Vehicle Pilot Deployment Program is a national effort to deploy, test, and operationalize cutting-edge mobile and roadside technologies and enable multiple connected vehicle applications.

In September 2015, USDOT awarded three cooperative agreements collectively worth more than $45 million to three sites for regional connected vehicle pilots:

  • New York City, New York
  • Wyoming
  • Tampa, Florida

The locations were selected in a competitive process to go beyond traditional vehicle technologies to help drivers better use roadways, relieve stress caused by bottlenecks, and communicate with pedestrians.
