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.
