New research presents the European cities with the highest traffic congestion. The INRIX Global Traffic Scorecard measures traffic speeds, congestion, bicycle trips or time spent on public transport.

In general, the roads of the most congested European cities do not respond sufficiently to car traffic. Seven of the slowest traffic flows are capitalized.

Rome is the busiest city in Europe and costs the average driver 166 hours of lost time, followed by Paris (165 hours), Dublin (154 hours), St. Petersburg (151 hours) and London (149 hours). Note that the hours lost driving in Athens are 109 and in Thessaloniki 51.

Traffic speeds are so slow in all five cities (except St. Petersburg) that the time spent on cycling or using public transport is only 50% shorter than driving.

The results make it clear that cities need to keep up with changes in mobility and traffic flow optimization. Especially since most metropolises continue to grow rapidly.

The INRIX Global Traffic Scorecard also calculated the financial impact when drivers got stuck in traffic in both Germany and the UK. Traffic congestion cost the German economy an estimated 2.8 billion euros last year. In Munich, the time loss cost 774 euros per driver in 2019, 587 euros per driver in Berlin and 445 euros in Düsseldorf.

Damage to the UK economy was even greater at £ 6.9 billion, with London holding the lion’s share of £ 4.9 billion, equivalent to £ 1,162 per driver.

Globally, Bogotá, Rio de Janeiro, Mexico City, Istanbul, and Sao Paulo are the five most congested cities in the world due to their urban density. However, INRIX also notes that Singapore’s robust anti-congestion policy, including high vehicle ownership costs and congestion taxes, allows the city’s road network to maintain high speeds despite its high urban density.

These are the top 10 European countries with the highest traffic congestion:
