Lesson Background HTML
Interstate 80 (I-80) in southern Wyoming is a major corridor for east/west freight movement and moves more than 32 million tons of freight per year. During winter seasons when wind speeds and wind gusts exceed 30 mi/h and 65 mi/h respectively, crash rates on I-80 have been found to be three to five times as high as summer crash rates. This resulted in 200 truck blowovers within four years and often led to road closures. The Wyoming Department of Transportation (WYDOT) CV Pilot site focuses on the needs of the commercial vehicle operator in the State of Wyoming and are developing and deploying applications that use vehicle to infrastructure (V2I) and vehicle to vehicle (V2V) connectivity to support a flexible range of services from advisories including roadside alerts, parking notifications and dynamic travel guidance. This WYDOT CV Pilot is expected to reduce the number of blowover incidents and adverse weather related incidents (including secondary incidents) in the corridor in order to improve safety and reduce incident-related delays.
WYDOT will develop systems that support the use of CV Technology along the 402 miles of I-80 in Wyoming. Approximately 75 roadside units (RSUs) that can receive and broadcast messages using Dedicated Short Range Communication (DSRC) will be deployed along various sections of I-80. WYDOT will equip around 400 vehicles, a combination of fleet vehicles and commercial trucks with on-board units (OBUs). Of the 400 vehicles, at least 150 will be heavy trucks that are expected to be regular users of I-80. In addition, of the 400 equipped-vehicles, 100 WYDOT fleet vehicles, snowplows and highway patrol vehicles, will be equipped with OBUs and mobile weather sensor.
