ACCOMPLISHMENTS 2019 Highlights Statewide master plan for ITS: a guided plan of deployment of ITS devices and systems will ensure traffic is being managed safely and effectively through technology solutions. Automated variable speed limit (VSL) software deployment: VSL corridors are now being planned statewide. VSL improves safety and traffic flow during weather, congestion, and other issues.
The Intelligent Transportation Systems (ITS) Deployment and Maintenance program uses state and federal funding to optimize mobility by improving UDOT’s ability to collect and disseminate traffic information. The program provides for expansion of UDOT’s fiber optic communication network, software, and devices, like cameras, overhead signs and traffic sensors, that allow UDOT to: • Explore, test and deploy new traffic management and operations technology and strategies, such as connected and autonomous vehicle (CAV) technology. • Continually manage the traffic signal network to help traffic flow more smoothly • Provide road users with information about traffic incidents, weather, construction delay, and travel times • Monitor traffic and quickly respond to mitigate the effects of crashes and disruptions. • Help maintenance crews anticipate weather and clear snow efficiently • Manage Express Lanes to keep all lanes operating at optimal levels • Support Utah Highway Patrol efforts to clear incidents quickly • Adjust freeway ramp meters to smooth out traffic flow
Fiber optic network expansion: new connections were made to UDOT maintenance sheds, traffic signals, and ATMS devices statewide. Variable message signs (VMS) end-oflife replacement: 12 variable message signs in Region 2 were replaced. Fiber optic systems end-of-life replacement: switches and other equipment in 4 fiber hubs and cabinets statewide were updated. Substandard in-ground fiber boxes were replaced. RWIS systems maintenance and upgrades: 135 components at various locations statewide were replaced.
The Traffic Management Division has expanded the Road Weather Information Systems (RWIS) network in Utah to 134. RWIS stations measure atmospheric conditions and transmit data to UDOT’s Traffic Operations Center where meteorologists can make forecasts to support snow removal or construction efforts. Page 11
