In car navigation producer TomTom has used anonymised data harvested from its devices to compile a ‘Congestion Index’ for Europe. Warsaw is in top place as Europe’s most congested city, followed closely by Marseilles and Rome.
The index was compiled by comparing the length of time a particular journey takes in low traffic conditions with the time when traffic volume is at its highest and aggregating the results. On average a peak traffic journey in Warsaw takes 58 minutes longer than its low traffic counterpart.
