New traffic data suggest Los Angeles, NYC no longer top most-congested U.S. cities

Each year, mobility data company Inrix conducts a traffic and congestion study that covers six continents, 38 countries, and more than 200 cities. According to its 2018 findings, L.A. no longer reigns as the worst city for driving. That crown now belongs to Boston.

Inrix bases its rankings on two things: hours and money lost to traffic (Inrix defines hours lost as “the total number of hours lost in congestion during peak commute periods compared”). For 2018, the five most congested cities in the country were Boston, Washington, D.C., Chicago, New York City and Los Angeles. This goes against the general assumption that L.A. and NYC have the worst traffic in the country.
