The goal of optimizing mobility continues to include the need to build new highways, expand existing highways, build more bicycle and pedestrian paths and expand the transit network. UDOT accomplishes this by adding capacity, managing lanes, developing innovative cross roads, coordinating signals, and providing traffic information.
Since 2006, more than 575 lane miles have been added to the state system from various programs that fund more than 100 projects. Currently, capacity projects are primarily funded through the Transportation Investment Fund (TIF). Some of these projects include the I-15 CORE, Mountain View Corridor, US-40 passing lane improvements, SR-18 intersection upgrades at St. George Blvd. and US-6 passing lane improvements. These capacity projects dramatically improve delay on Utah roadways.
UDOT currently has 124 miles of Express Lanes (62 miles both northbound and southbound) with 54 continuous miles between Spanish Fork and North Salt Lake City making Utah’s Express Lanes the longest continuous Express Lanes in the country. More than 13,000 Express Pass transponders have been purchased, speeds average 9 mph faster than the general lanes and travelers experience a higher level of safety.
Developing and constructing innovative cross roads is a fundamental in optimizing mobility on Utah roadways. Flex Lanes, Commuter Lanes, ThrU-Turn Intersections (TTI), Diverging Diamond Interchanges (DDI) and Continuous Flow Intersections (CFIs) decrease delay at intersections, reduce travel time, improve safety, and reduce the length and cost of construction.
The Traffic Operations Center (TOC) continues to be the key to providing a cost-effective and and efficient solution to help relieve congestion on Utah’s roads and highways. Using advanced technologies such as cameras and traffic/weather sensors, operators in the TOC can monitor traffic, detect problems and take actions necessary to return traffic flow to normal.
UDOT uses a variety of methods to provide actual travel times and accurate traffic and weather information to help drivers make choices that reduce delay, prevent crashes and improve air quality. By implementing an extensive Intelligent Transportation System (ITS), UDOT is able to know what is happening on Utah roads, and provide travelers the information they need to plan their routes. UDOT communicates travel information online at udot.utah.gov and through variable messages signs (VMS), traffic cameras, twitter, facebook, and YouTube, and the UDOT Traffic App.
