April 27, 2014 marked the 15 year anniversary of the UDOT Traffic Operations Center (TOC) opening its doors. The UDOT TOC was built to manage congestion and traffic during the 2002 Olympics. While managing traffic for this important special event was a catalyst for building the TOC, UDOT fully understood that there would be significant benefits to operating the TOC long term.

As Utah continues to grow, so does the challenge of mobility. To address Utah’s transportation challenges, the Utah Senate passed a Senate Bill in 1995 and established a Traffic Management Committee which consisted of representatives from Salt Lake City, Wasatch Front Regional Council, Mountainland Association of Governments, Salt Lake County, the Department of Public Safety and the Utah Department of Environmental Quality. This committee recognized the benefits of a Traffic Operations Center to manage traffic and improve roadway efficiency.  The Utah Transit Authority and Federal Highway Administration also partnered with the committee. The committee determined that a TOC was necessary and shortly after, planning started on where the TOC would be built, what components it would have and how the information would be distributed to the public.  A common ITS architecture was established, which now allows all Utah jurisdictions with ITS devices to share resources.

When the doors opened in 1999, the TOC was staffed Monday – Friday 5:00 a.m. – 11:00 p.m. and covered a limited number of routes on the Wasatch Front. Utah’s ITS system was given the name “CommuterLink” because it was largely commuter-centric traveler information and congestion management for Salt Lake City. Today, the TOC is staffed 24/7/365 and manages traffic statewide. To reflect the statewide approach, the system is now known as “UDOT Traffic”.

Over the years, the TOC has grown its traffic management capabilities and has added extra equipment to keep up with Utah’s transportation demands. In 1999, UDOT had deployed 150 traffic cameras and 57 Variable Message Signs (VMS). Today, UDOT has a sophisticated statewide network that includes over 900 traffic cameras and over 150 VMS! These valuable tools can be viewed on the UDOT Traffic smartphone app and website. Traffic camera images are also shared with the media and can help commuters make travel decisions while watching the morning news. UDOT’s fiber optic network is also robust – with over 1800 miles of fiber optic cable deployed, UDOT has one of the most complete and useful fiber optic networks in the nation. This network helps to establish lightning-fast communications with traffic signals, VMS, traffic detectors and other equipment throughout the state. From the TOC, UDOT can manually operate over 85% of the traffic signals throughout the state… as far away as St. George, Moab, Vernal and Logan!

The UDOT Traffic Operations Center has deployed a statewide traffic management network.

From its first years of operation, the TOC has proven its effectiveness. The system has helped to increase peak-hour freeway speeds, reduce freeway delays and improve traffic signal efficiency. Traffic management is an important component of a healthy transportation network. UDOT’s TOC supports other UDOT divisions to successfully build, maintain and operate Utah’s highways. UDOT’s TOC also helps to support UDOT’s Strategic Goals: Preserve Infrastructure, Zero Fatalities, Strengthen the Economy and Optimize Mobility.

Congestion from these incidents often generates secondary crashes, further increasing traveler delay and frustration. The longer incident responders remain at the scene, the greater the risk they, and the traveling public, face.

To minimize delay and improve responder safety, UDOT and UHP hosted a Traffic Incident Management (TIM) workshop on April 9 – 10 in Salt Lake City. Participants from UHP, Unified Fire, Unified Police, UDOT, trucking companies, the St. George Police Department and other agencies were in attendance. UHP Colonel Daniel Fuhr and UDOT Traffic Management Division Director Rob Clayton welcomed the participants with information on crash statistics, our responsibility to the public, and the importance of protecting first responders from harm.

TIM Training attendees participated in a table-top exercise on scene management.

The National TIM Responder Train-the-Trainer (TtT) program provided participants the knowledge and materials necessary for them to conduct TIM training for TIM responders in their area. The TtT is a 1½-day course that covers the fundamentals of Traffic Incident Management, safe crash scene set-up, quick incident clearance and on-scene coordination.

Participants were able to learn from course instructors who were former first responders. Participants were also able to participate in a tabletop exercise as well as learn about proper accident scene set-up.

Traffic incidents, including crashes, disabled vehicles and debris on the road create unsafe driving conditions, put motorists and responders at risk, and account for approximately 25 percent of all traffic delays.

For each minute that a freeway travel lane is blocked during peak use, an estimated 4 minutes of delay result after the incident is cleared. This estimate accounts for 4.2 billion hours per year in delays. Additionally, the U.S. Department of Transportation reports that Americans burn more than 2.8 billion gallons of gasoline every year while stuck in incident-related traffic. TIM Training can give us the tools to clear incidents more quickly, saving time, money and lives. More information can be found on the National Unified Goal for Traffic Incident Management website.

The training was made possible through a Federal Highway Administration Strategic Highway Research Program.

Behind the Scenes at UDOT – November 22, 2013 Wind Storm Response

UDOT Wind Event Weather Briefing

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.

Utah’s unique geography can be a challenge for traffic management and safety. Many of the critical highway routes in the state are in rural areas and can be prone to flooding, snow drifts, landslides, high winds or low visibility due to wild fire smoke. UDOT’s Road Weather Information System (RWIS) network currently has nearly 80 deployments throughout the state. An RWIS unit has several weather sensors that calculate wind speed, precipitation type, roadway temperature and more. Some RWIS have a traffic camera as well.

Utah has had an active winter and spring with several large storms, flooding and landslides. In June, UDOT deployed a portable RWIS unit near Monument Peak on SR-31. This site was adjacent to an area that was burned in a forest fire and was at risk for landslides. The portable RWIS can be relocated at a later date for other uses. The RWIS sends alerts to the UDOT Traffic Operations Center (TOC) meteorologists who can then contact UDOT crews and UDOT management working in a specific area and alert them to any danger of landslides or flooding. The alert information is also shared with the National Weather Service, the National Forest Service, the United States Geological Survey, Utah Highway Patrol and other agencies. UDOT contracts with Northwest Weathernet for meteorological services and RWIS installation.
