A composite metric for infrastructure is based on the following key performance measures:
Through a proactive asset management approach, the overall conditions of bridge and pavement systems continue to improve. The gas tax enacted in 2016 will allow us to invest in strategic enhancement of our low volume roads and bridge systems, demonstrating that, “good roads cost less.”
We apply the same philosophy to the management of our ATMS and signal system. We’re improving our data collection and life-cycle cost planning as the size of our systems grow.
Under the philosophy, “good roads cost less,” UDOT manages more than 16,000 lane miles of pavement throughout the state. We take a proactive approach to preserve and rehabilitate these assets to achieve the greatest long-term benefit. Pavement is prioritized in two categories based on the volume of daily vehicle usage and the volume of freight:
The condition of bridges in our inventory is the envy of the country. We strategically invest our funding to proactively preserve, rehabilitate and reconstruct our structures when needed. UDOT uses the Bridge Health Index (BHI) which measures and tracks the overall structural condition of a bridge. Our Bridges are categorized by the following:
Maintaining and repairing our traffic signals and advanced traffic signal ensures consistent reliability and extends the life-cycle of these devices. This proactive approach includes determining the end-of-life for each device to determine when service will be needed to replace, upgrade, or decommissioned as well as detect the number in good working condition.
UDOT is adopting a complete lifecycle approach to ATMS devices and traffic signal management to achieve system reliability. This proactive approach includes determining the end-of-life for each device to determine when service will be needed to replace, upgrade or decommissioned as well as the number in good working condition.
Data on pavement condition is collected every year. In the bar chart below data for 2018 to 2022 is a forecast.
Target: Utah’s overall roadway condition is 80% fair or good.
Bridge inspection is occurring year-round resulting in a frequency of every structure every two years. In March of each year, the BHI score of each structure inspected in the previous 12 months is updated. In March of each year, each structure is inspected and scored out of 100 using the Bridge Health Index (BHI).
The Bridge Health Index of the National Highway System (NHS), State, and Local Governments and Municipalities is tracked.
These devices and signals are key infrastructure measurements to manage traffic, and provide a safe, and reliable movement of goods, services and people. The department tracks the health of these through ongoing preventative maintenance and performance monitoring.
This number is determined by the percentage of operational devices.
Target: 95 percent of devices in operation
This number is determined through an annual assessment that includes all electronics and physical infrastructure.
Target: 95 percent of signals in average condition or above
