What too much traffic does to our environment — and to us
Germany's congestion capital
Germany saw roughly 745,000 traffic jams in 2018, according to German automobile club ADAC. That's a three-percent increase compared to 2017. According to GPS-maker TOMTOM's last survey, Cologne's streets were the most congested (as shown above). On average, travel time increased by more than a third because of congestion, compared to free flowing traffic.
