An annual ranking of the world’s most traffic-congested cities offers insights that might be useful to city leaders. Urban commuters spend an average of eight days stuck in traffic each year. Building more roads doesn’t always alleviate the jams, writes Jim Gorzelany, a Chicago-based automotive journalist, in Forbes.

In fact, secondary roads can be worse than major arteries, according to stats compiled by TomTom, an Amsterdam-based company that makes navigation devices for vehicles. “The traditional responses to congestion, such as building new roads or widening existing ones are no longer proving to be effective,” TomTom CEO Harold Goddijn tells the publication.

Los Angeles may have the most congested roads of any U. S. city, but it only ranks ninth worldwide. The most traffic-clogged metropolis out of 180 surveyed is Moscow, where delays average 76 minutes for every hour driven during peak travel times. That means a trip that should take one hour takes more than two hours during rush hour. Rounding out the top ten are Istanbul, Rio, Mexico City, São Paulo, Palermo (Italy), Warsaw, Rome, L. A. and Dublin.

The latest index, which reflects 2013 traffic levels, was released in June and is available here
