Not really news to those of us who live here (personally I simply will not drive anywhere during rush hour, it's just not worth the aggravation).
TomTom today launches the first quarterly Congestion Index that accurately identifies and analyses traffic congestion in major cities across Europe. The report, initially covering 31 cities, finds Warsaw the most congested city in Europe. On average, journey times in Warsaw are 42% longer than when traffic in the city is flowing freely and 89% longer during morning rush hour.
The top ten most congested cities, ranked by overall congestion level, between January and March 2012 were:
1. Warsaw, 42% congestion level 6. Dublin, 30%
2. Marseille, 41% 7. Bradford - Leeds, 28%
3. Rome, 34% 8. London, 27%
4. Brussels, 34% 9. Stockholm, 27%
5. Paris, 32% 10. Hamburg, 27%
