Getty Images "What is the solution to the problem of traffic jams?" a Turkish journalist asked Nick Cohn, senior product manager at TomTom, at the end of 2019. His response, "We can't keep building extra lanes endlessly; that's not a long-term solution." Then he adds, "We need sustainable alternatives for transporting large groups of people, and we need to spread the traffic more." The past year shows that these solutions do indeed work to combat congestion. In 2020, there was a 19% reduction in congestion worldwide, according to the new TomTom Traffic Index. "In terms of mobility, 2020 has been one big experiment," says Gijs Peters, data scientist and traffic expert at TomTom.
