London tops gridlocked cities

LONDON, 16 March 2016: London tops the list of traffic gridlocked cities according to a traffic scorecard released by INRIX, a global leader for connected car technology and transportation analytics.

INRIX has published its 2015 Traffic Scorecard, a benchmark for governments and cities in Europe and the US to measure progress in improving urban mobility.

Of 100 cities, worldwide, London topped the list, with drivers wasting an average of 101 hours, or more than four days, in gridlock in 2015.

inside no 7Across the UK, drivers spent 30 hours on average in delays last year, consistent with 2014, but the UK dropped to sixth in the European ranking as a result of Switzerland seeing a rise in traffic levels.

Belgium remains Europe’s most gridlocked country, with drivers stuck in traffic for 44 hours on average.

Urbanisation is a key driver of congestion, and London’s population topped 8.6 million6 last year, the highest since its 1939 peak. This contributed to drivers in the capital spending a record 101 hours on average stuck in traffic, the first time a city has surpassed 100 hours wasted in gridlock in a year. As a result, London tops INRIX’s congestion ranking of major cities worldwide and remains Europe’s gridlock capital for the second year running.

“London is the victim of its own success, with a robust jobs market and a growing economy attracting more people,” said Bryan Mistele, President & CEO, INRIX.

inside no 7.1Although London topped the list of Europe’s most gridlocked cities, Stuttgart experienced the highest increase, reaching 73 average hours wasted in 2015, an increase of 14% from 2014. This propelled Stuttgart from fifth to second in the ranking, which can be attributed to low fuel prices9, a record number of new registered vehicles10 and more people commuting to work by car. Cologne, which took the title of Germany’s most congested city last year, slips to fourth, and Antwerp moves up to third. Both Cologne (5.2 hours) and Antwerp (6.6) experienced significant increases in delays.

Brussels – Europe’s most congested city in 2012 and 2013 and second to London in 2014 – experienced a significant drop in delays in 2015, achieving 70 hours wasted in traffic, a decline of more than four hours from 2014 and moving the city to fifth in the ranking. Brussels recently made investments to strengthen key suburban rail services in and around the city to help ease gridlock.

At the global city level, London tops the list of gridlock-plagued cities, with 101 hours of delay, followed by Los Angeles (81 hours), Washington DC (75), San Francisco (75), Houston (74), New York (73), Stuttgart (73), Antwerp (71), Cologne (71) and Brussels (70).

Of the countries measured by the INRIX Traffic Scorecard, the US leads with the highest annual hours wasted in traffic – an average of nearly 50 hours in 2015 – outranking Belgium (44 hours), Netherlands (39), Germany (38), Luxembourg (33), Switzerland (30), UK (30) and France (28).
