The New York urban area is the most populous in the nation, and is home to over 19 million people. Partially as a result, both delays due to traffic and congestion costs are highest in the country. Auto commuters lose more than 628 million hours to delays each year, costing roughly $14.7 billion, the highest added driving time and the most costly traffic system among U.S. cities. Four of the nation’s 20 most congested stretches of road are in the New York City area, including the northbound I-678, and both directions of I-495.

Most New York residents choose to avoid traffic. Just over 27% of the area’s population commutes by car, the lowest share among the 101 cities the TTI reviewed. And 32.6% of workers use public transit, the largest share nationwide.
