St. Louis, MO--IL Urbanized Area Congestion Report

In the line graphs below, FHWA uses Data Collection Year instead of Data Reporting Year to represent snapshot condition/performance at the time the data was collected. More information

The St. Louis, MO--IL Urbanized Area covers parts of Illinois and Missouri. Targets are agreed upon by several transportation agencies and apply to the entire area.

  • Annual Hours of Peak-Hour Excessive Delay (PHED) Per Capita

    • Trend through 2025

      Desired trend: ↓

    Targets -- -- 8.4 -- 8.3

  • Annual Hours of Peak-Hour Excessive Delay (PHED) Per Capita

    (Illinois) A hybrid target setting approach was used. This approach combined historical data from NPMRDS INRIX to establish a pre-pandemic PHED baseline between 9.2 and 9.6 hours and also analyzed monthly PHED data in 2021.

    (Missouri) A hybrid target setting approach was used. This approach combined historical data from NPMRDS to establish a pre-pandemic PHED baseline between 9.2 and 9.6 hours with analysis of 2021 monthly PHED data

  • Non-Single Occupancy Vehicle (Non-SOV) Travel

    Targets -- -- 18.0 -- 18.2

  • Non-Single Occupancy Vehicle (Non-SOV) Travel

    (Illinois) From 2012 to 2019, Non-SOV mode share has remained relatively constant, with slight increases and decreases which may be explained by the sample data utilized by the American Community Survey. In 2020, Non-SOV travel increased to 19.5%. This increase can be attributed to the COVID-19 Pandemic and the resulting decrease in overall travel due to increased telecommuting. In 2021, individuals returned to commuting, however, there is a higher rate of telecommuting compared to pre-pandemic years. This is likely a fundamental change in commute patterns which leads to a higher two-year and four-year targets.
