Behind the Scenes at UDOT – November 22, 2013 Wind Storm ResponseOptimize Mobility, by Lisa Miller.
Weather events can have a huge impact on traffic and traveler delay. The UDOT Traffic Operations Center (TOC) handles routine day-to-day rush hour congestion and traffic signal timing smoothly after years of practice. But what about a large winter storm or wind event?
A significant amount of planning and consideration is needed to ensure that UDOT’s response to a storm is thorough and serving the needs of the public. For the high winds event that affected interstate and highway routes from Woods Cross to Centerville on Nov.21–22, 2013, TOC coordination started with a weather briefing. Weather briefings are generally held 24 to 48 hours before a storm to ensure that the incoming weather data is as accurate as possible. Many UDOT departments attend the weather briefings. The briefings are an essential tool to ensure that the UDOT response to an event
is coordinated and timely. “The weather briefing discussed what we anticipated, what steps they would take when certain thresholds were met, and a detailed schedule of who would be in charge throughout the event,” said Jason Davis, UDOT’s Director of Operations.
Following the weather briefing, UDOT employees sprang into action. UDOT began strategically deploying equipment and personnel to assist with equipment malfunctions and outages due to the storm. The Traffic Operations Center had an event coordinator and meteorologist on staff around the clock for the duration of the event.
One of the most valuable pieces of equipment during a wind storm are the Road Weather Information System (RWIS) stations. A portable RWIS was deployed at the epicenter of the wind and communicated wind speeds and gusts back to the TOC. Over the course of the storm, the UDOT weather group posted dozens of Road Weather Alerts on the UDOT Traffic app, website and 511 phone line. The weather group was also in near-constant communication with UDOT’s region offices and maintenance sheds providing storm updates.
