Methodology

To identify the city with the worst traffic in every state, 24/7 Wall St. reviewed data from the 2022 Global Traffic Scorecard, from INRIX, a traffic data and analytics company. We used the average time the typical commuter lost to traffic congestion in 2022 in the 280 U.S. cities with available data. Within each state, we identified the city with the most time lost to traffic congestion. 

Due to a lack of data, Alaska, South Dakota, Vermont and Wyomingis not included on this list. We did include Washington, D.C., however, which is one of six states or districts that is home to only one city with available data. In these places, which are noted, the city listed ranks as having the worst traffic by default. 

Supplementary data on average commute time for those not working from home and the number and share of commuters who drive or carpool to work are five year estimates from the U.S. Census Bureau’s 2021 American Community Survey. Due to a lack of ACS data at the city level for Ocean Township, New Jersey, we used data for Monmouth County, which is where Ocean Township is located.

Data on change in the average traffic delays from 2021 is also from INRIX.
