TomTom used GPS data to compare travel times during the whole day and during peak periods to travel times during non-congested periods. Includes cities with a population of 800,000 or over. 2018 figures are based on 2016 TomTom traffic data.
The statistic shows the most traffic jam prone cities in Europe in 2018. With an overall congestion level of 50 percent, Bucharest was the second most congested city in Europe. Here, a trip that might take 60 minutes in non-congested traffic will take 57 minutes longer during rush hour.
