Bike Lanes Don't Cause Congestion

Research from Europe shows bike infrastructure doesn't add to urban traffic and can shift mode share from cars to bikes and reduce the need for solo car trips.

Despite claims that cycle lanes added during the pandemic contributed to an increase in London's traffic congestion, research shows the city's traffic was largely the same in 2021 as in 2019, before the bike lanes were installed. David Metz reports that cycle lanes actually reduce the share of trips taken by car, which could diminish congestion as well. Thanks in part to aggressive measures taken by the city to discourage car trips, the use of private transport in London fell from 48 percent to 37 percent between 2000 and 2019.

"It’s important to note that creating cycle lanes reduces the space available for cars but does not necessarily get people out of cars. Copenhagen is a city famous for cycling, with 28 percent of journeys made by bike. Yet car traffic is only slightly less than in London." Meanwhile, residents of Copenhagen take only half as many public transit trips as Londoners. In fact, "there are no major European cities with high levels of both cycling and public transport. " 

With revenues from public transit ridership drastically reduced by the pandemic, Metz writes, it is investments in cycling infrastructure that would "make the most sense for reducing car use in London."
