Istanbul second most congested city in the world

Istanbul is the second most congested city in the world behind Moscow, research has revealed.

TomTom today announces the 2012 Congestion Index, a report comparing congestion levels in 2012 versus 2011 in 161 cities and across five continents. The Annual Congestion Index finds Moscow the most congested city.

On average, journey times in Istanbul are 55% longer during non-congested periods when traffic is flowing freely, and 80% longer during morning rush hour. Istanbul commuters spend 118 hours a year in traffic.
