UDOT RWIS network
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.

The UDOT Traffic Management Division (TMD) houses UDOT’s Traffic Operations Center (TOC), the traffic signal management division, traveler information program and deployment and maintenance for Utah’s robust Intelligent Transportation System (ITS) network. UDOT utilizes the resources from within the TMD to plan for and react to any type of event that reduces capacity on Utah interstate and highway routes.
The UDOT TOC is operated 24 hours a day, 7 days a week, 365 days a year! TOC operators actively monitor traffic, looking for road debris, crashes or lane closures due to construction. This sophisticated ITS network includes traffic cameras, overhead message signs, vehicle detectors and much more. The fiber optic network that connects the ITS devices to the TOC provides an excellent, fast connection that allows TOC operators to react at a moment’s notice. “Our TOC operators monitor traffic throughout the state from our facility in Salt Lake City. If a crash occurs in St. George, our operators are able to use traffic cameras to locate the incident and post a message warning motorists on an overhead message sign within a matter of seconds,” said Mike Evans, Control Room Manager.
In addition to day-to-day traffic problems, the UDOT TMD also provides traffic signal support for large-scale special events. A signal management operator can remotely control nearly 80% of UDOT’s traffic signals from the TOC.
UDOT’s Traffic Management Division is charged with operating a smart transportation network. Using technology to help manage traffic is an excellent way to optimize mobility, reduce delay and increase roadway capacity.

UDOT Executive Director John Njord presented two Traffic Management Division employees with Silver Barrel Awards yesterday.
Rob Clayton, Matt Luker and John Njord
Matt Luker received his award for his efforts on the Flex Lanes project. This project had several difficult engineering aspects as well as some challenging software programs. The Flex Lanes project on 5400 South in the Salt Lake Valley allows for more dynamic use of the roadway depending on the conditions and heaviest direction of travel. The Flex Lanes project optimizes mobility on this busy corridor. Matt was involved on the design, testing and troubleshooting of this project for over 3 1/2 years. Matt is a signal engineer responsible for corridor-wide signal timing in UDOT’s Region 4 as well as for special projects. Prior to his current role, Matt was an Assistant Signal Engineer. Matt has worked for UDOT for 4 1/2 years.
Rob Clayton, John Njord, and Chuck Felice
Chuck Felice received his award for managing the design and production of the UDOT Traffic smartphone app. The UDOT Traffic has been downloaded over 150,000 times since its launch in November 2011. More recently,Chuck managed the project to add additional alerts to the UDOT Traffic app and website. John Njord gave Chuck his Silver Barrel Award and mentioned that he is proud of the work that is done within the UDOT Traffic Management Division. Chuck delivers the projects that he manages effectively, however he always strives to deliver more than was asked of him. Chuck is the lead software developer for UDOT’s Traffic Management Division and is responsible for software design and integration. Chuck has worked for UDOT for 6 1/2 years.

Preserving Utah’s road infrastructure is a critical component of UDOT’s Strategic Goals. The UDOT Traffic Management Division is creating an Asset Management Plan for devices within the Advanced Traffic Management (ATMS) System to help UDOT to continue its proactive maintenance of field devices. Devices the plan will take into account include traffic cameras, variable message signs (VMS), pavement detectors, road/weather stations, etc. An Asset Management Plan can also help to identify funding sources for new and replacement equipment.
With over 1800 devices throughout the state and over 1800 miles of fiber optic cable to maintain, each of UDOT’s 16 technicians are responsible for over 100 devices. “Our staff is responsible for troubleshooting, corrective maintenance, ordering replacement parts and device installation. With a statewide system to maintain, some of these tasks can take up to a half day to complete per device,” said Brad Lucas, UDOT ITS Systems Engineer. Long term performance of the system relies on good maintenance now and allows for easier expansion and replacement in the future.
UDOT’s strategy must have a statewide approach and address long term system growth and health. “Some components of our infrastructure are aging, and good system maintenance helps to extend the life of the equipment,” said Lucas. UDOT’s Asset Management Plan will research the best and most meaningful use of public resources when budgets are tight and demand for data from field devices is high.
UDOT currently achieves between 85% and 90% of all system devices are fully operational. An Asset Management Plan will help to raise those percentages, identify life cycles for equipment replacement and strategically manage the equipment to ensure its long-term performance. Keeping the equipment operational helps to manage traffic more efficiently, and having reliable statistics on how the system is performing is an important metric for how public funds are spent.
An inauguration of an elected official is an exciting event, and UDOT was on hand during the January 7, 2013 inauguration of Governor Herbert to ensure that traffic moved smoothly. UDOT was contacted by Capitol staff ahead of the inauguration hoping to mitigate traffic problems that were observed during previous inauguration events. The UDOT Traffic Management Division (TMD) and UDOT Region 2 were tasked with using the knowledge and tools available to ensure that traffic delays were at a minimum during this important event.
“The staff at the UDOT TMD and Region 2 went above and beyond to help get attendees of Governor Herbert’s inauguration where they needed to go safely and with little confusion or traffic delay,” said Eric Rasband, UDOT Engineer-in-charge for the event.
UDOT’s duties were to coordinate signal timing plans, attend pre- and post-event meetings, coordinate with Capitol employees and local police as well as handle traffic control and snow/ice removal. UDOT also utilized its social media outlets for parking alerts and related information.
The total attendance for the event was between 1000 and 1500. Overall, traffic moved very well and there were no major delays.
