TomTom’s latest Congestion Index shows that Istanbul is the most congested European city.

The Congestion Index measured traffic congestions in 58 European cities between April and June 2012, and found that Istanbul is the most congested city on the continent. Average journey times in this city are 57% longer compared with freely flowing traffic times, and 84% longer during morning rush hour.

TomTom’s Congestion Index is the most accurate barometer in the world, when it comes to congested urban areas, and it is based on real travel time data, which is gathered by vehicles driving the entire road network. The index shows that between April and June 2012 the overall Congestion Level in Europe dropped 4% to 23% compared with the same period last year.

Here is the list of the top 10 most congested cities in Europe:

4. Palermo 40%
5. Rome 34%
6. Paris 34%

“This Congestion Index gives the general public, businesses, industry and policy makers accurate and unbiased information about congestion levels in urban areas. Because TomTom’s traffic information is so precise, we can pinpoint congestion trouble spots more effectively,” said Ralf-Peter Schäfer, Head of Traffic at TomTom.
