To determine the worst cities to drive in, 24/7 Wall St. created an index assessing the safety, cost, and convenience of driving in America’s metropolitan statistical areas. Data on the number of traffic fatalities in 2018 from the Fatality Analysis Reporting System were adjusted for population using data from the U.S. Census Bureau’s 2018 American Community Survey. Data on the number of traffic fatalities involving drunk drivers, also from FARS, were adjusted for population using 2018 ACS data. Data on the mean travel time to work for the population 16 years and over came from the 2018 ACS.
Data on the number of car thefts per 100,000 people came from the National Insurance Crime Bureau’s 2018 “Hot Spots” report.
Data on the average cost of fuel per auto commuter accrued while sitting in traffic in 2017, as well as the average number of hours of delay spent in traffic per auto commuter in 2017, came from the Texas A&M Transportation Institute’s 2019 Urban Mobility Report and were aggregated from the urban area level to the metropolitan statistical area level using geographic definitions from the Census Bureau.
Data on the average annual state auto insurance rate came from personal finance company Bankrate. This data was not included in the index.
