(LONDON) – London is the most congested city in Europe, according to traffic provider NAVTEQ.
The company released a list of Europe’s 10 most congested cities in regards to traffic, based on the duration of rush-hour delays in cities with more than one million people.
Paris came in second on the list, followed by Dublin, Berlin and Stockholm. Others cities on the list include Hamburg, Manchester, Lyon, Vienna and Marseilles.
According to NAVTEQ, traffic congestion can be caused by a combination of topographical characteristics, population and transportation systems.
"These circumstances and many others intersect with time to produce traffic," said Andreas Erwig, Director of NAVTEQ Traffic Europe. "Because the fascinating complexity of traffic is that it's not only about movement from here to there, but from now to then."
GPS, sensor data and information from police and emergency services were used to gather information for the study.
