ATMS ASSET MANAGEMENT & MAINTENANCE

The ATMS Asset Management and Maintenance program increases system safety and reliability by replacing and updating Advanced Traffic Management Systems (ATMS) devices.

ATMS unites traffic monitoring stations, road weather stations, traffic cameras, and other system components, with a power and communications backbone that allows UDOT to manage traffic in real time. A high-functioning ATMS system significantly reduces fatalities and injuries and optimizes mobility.

At end-of-life, ATMS devices can be unreliable or broken. Systematic device replacement is a holistic approach that conserves funding and supports the functionality of the entire transportation system.

UDOT ATMS has experienced tremendous growth since the Traffic Operations Center opened in 1999. The system now includes over 2000 devices, along with supporting electronics. Without a plan to replace these devices, the system would become increasingly unreliable and costly to maintain.

Program activities include: • Replacing unreliable or non-functioning ATMS devices past end of life • Replacing ATMS devices that will reach end-of-life in current and future fiscal years before normal traffic flow is interrupted • Upgrading supporting equipment and electronics such as communications hub switches, power transformers and the communications backbone • Replacing broken communications junction boxes
