Istanbul and Mexico City have tied for the dubious distinction of the most congested cities in the world, according to a study conducted by navigation systems producer TomTom.

The chart below, by Niall McCarthy and Statista, rankes the top 10 delinquents. Employees who have what would be a 30 minute commute without traffic in those cities spend 110 hours in gridlock in both cities every year. Moscow is close behind, with 109 hours of annual gridlock, followed by St. Petersburg. Only one U.S. city makes the ranking Los Angeles comes in at ninth, with 95 hours spent in stop-and-go traffic per year.
