What Is the Urban Mobility Assessment?

The Urban Mobility Assessment (UMA) is a study led by the Utah Department of Transportation (UDOT) to evaluate how roadway projects in Salt Lake City may have changed quality of life for residents, businesses, and people traveling through the city. Potential changes from these projects will be assessed both qualitatively and quantitatively.

As requested by Senate Bill 195 (SB 195), the study focuses on the area between Interstate 15 and Foothill Drive, from 2100 South to 600 North. The legislation requires:

• Salt Lake City to create a mobility plan for the area
• UDOT to analyze changes in mobility, traffic flow, environmental conditions, and community impact
• Evaluation of roadway projects built from 2015 to 2025, and assessment of planned projects through 2035

The final results — including recommendations for future project evaluations — will be submitted to the Utah Legislature’s Transportation Interim Committee in October 2025.

Why This Study Matters

SB 195 aims to verify that traffic-calming efforts in Salt Lake City align with state transportation goals and reflect the needs of motorists, pedestrians, cyclists, and local businesses.

To achieve this, the UMA team is analyzing a range of data sources to assess before-and-after project conditions, including:

• Traffic volumes, speed data, and crash statistics
• Transit, pedestrian, and bicycle activity
• Air quality readings
• Economic indicators such as sales tax revenue
• Public input from commuters, residents, and business owners
