Anyone driving to work this year may have noticed an uptick in congestion. As remote work plummeted and more workers returned to the office, millions of more cars were added to U.S. roads, contributing to traffic and causing hours of extra gridlock during peak hours.

Traffic jams are more than an inconvenience – they’re a massive drain on the economy. In 2024, U.S. drivers spent an average of 43 hours sitting in traffic – more than a full work week. Hampering productivity, disrupting supply chains, and squeezing local businesses, traffic congestion carries with it a serious economic toll, with delays costing the average U.S. driver $771 throughout the year.

While cities like New York and Chicago are famous for their traffic, the most congested cities are outside of the United States. A closer look at the data reveals the global cities losing the most time and money to traffic congestion.

To determine the cities losing the most money to traffic congestion, 24/7 Wall St. reviewed data from software company INRIX. Global cities were ranked based on the average number of hours lost sitting in traffic per driver in 2024. Traffic is defined as the additional time spent in congestion during peak commute periods compared to off-peak periods. Supplemental data on average downtown speed – the speed at which a driver can expect to travel one mile into the central business district during AM peak hours – are also from INRIX. Data on vehicles per capita are from the International Organization of Motor Vehicle Manufacturers.
