5 Most Congested Cities in Europe

4. Bucharest

Average Travel Time per 10 km: 27 Minutes and 40 Seconds

Bucharest, Romania’s southern capital, suffers from some of the world’s worst traffic. In 2023, congestion levels in the city hit a new high of 55%, adding 20 seconds to the travel time for a typical 10 km trip. This gridlock is partly fueled by an increase in car registrations, with a staggering 1.8 million vehicles now in Bucharest and its surroundings.
