Utah is ramping up its game against winter's bluster with a high-tech edge. The Utah Department of Transportation (UDOT) has announced that they are equipping an additional 100 snowplows with vehicle-to-everything (V2X) technology to better tackle the snow-laden roads across the state. This move follows the recent deployment of V2X units during this past Tuesday's heavy storm, noted for significantly speeding up clearing operations. According to UDOT, these wireless sensor units enable vehicles and infrastructure to communicate, paving the way for enhanced transit signal preemption among other benefits.
The implementation of transit signal preemption allows snowplows to request traffic signals to either extend the green phase or switch the red to green, ensuring that the plows keep moving. Challenges posed by the halted traffic and resultant road conditions are significant concerns during snow removal. "If traffic is stopped, we’re stopped. And the roads stay worse the longer we’re in traffic," said Brian Sommer, a snowplow driver at UDOT’s Provo/Orem maintenance station, as per UDOT. The introduction of more V2X-equipped plows means this year will see a doubling in UDOT's fleet capable of this sort of automation.
Increased efficiency isn't the only benefit; there's a notable improvement in safety conditions as well. With transit signal preemption, dangers associated with abrupt stops at red lights on icy roads are largely mitigated. "The safety aspect of it – being able to flow through an intersection without impeding traffic has been great," remarked Chad Gasser, Station Supervisor at UDOT Provo/Orem, as obtained by UDOT. "It’s making it safer for us, the public and commuters."
Looking ahead, the potential of V2X technology extends beyond its current uses. In the future, safety messages cautioning drivers about work zones, hazardous road conditions, or sharp curves will be transmittable, further aiding in crash prevention. Blaine Leonard, a UDOT Transportation Technology Engineer, emphasized the long-term vision, "In the long run, this technology is meant to save lives," he conveyed, as obtained by UDOT. Experiments with V2X technology date back to 2015 for UDOT, indicating a continued commitment to leveraging technology for road safety and efficiency in Salt Lake and Utah counties.
