Pop-Up Bike Lanes Increased Cycling During the Pandemic, Research Finds

Adding bike lanes to city streets can improve the variety of cyclists throughout a complete metropolis, not simply on the streets with new bike lanes, in response to a brand new research. The discovering provides to a rising physique of analysis indicating that investments in biking infrastructure can encourage extra folks to commute by bike, which helps scale back greenhouse gasoline emissions and enhance well being.

“It’s the first piece of evidence we have trying to, at a larger scale, link the bikeway infrastructure — these pop-up bike lanes and things that were built — to cycling levels during Covid,” mentioned Ralph Buehler, chairman of city affairs and planning in the School of Public and International Affairs at Virginia Tech, who was not concerned in the research.

The analysis, published online Monday in the Proceedings of the National Academy of Sciences, discovered that in cities the place bike infrastructure was added, biking had elevated as much as 48 p.c greater than in cities that didn’t add bike lanes.

Dense cities the place public transit was already in style usually noticed the largest will increase. In cities with decrease density, extra automobiles per capita and better site visitors speeds, the improve in biking was extra modest. Paris, which carried out its bike lane program early and had the largest pop-up bike lane program of any of the cities in the research, had one among the largest will increase in riders.

“It almost seems like a natural law that the more infrastructure you have, the more cycling you will have,” mentioned Sebastian Kraus, the research’s lead writer.

But in public transit analysis, the impact of including bike lanes is a matter of debate.

“It’s like a chicken and egg problem,” mentioned Mr. Kraus, a doctoral candidate in economics at the Mercator Research Institute on Global Commons and Climate Change in Berlin. “There can be this reverse causality that, actually, if you have a lot of cyclists, they will demand better infrastructure, and it’s not really the infrastructure that creates more cycling.”

The researchers collected knowledge, together with the lengths of recent bike lanes and knowledge from bike counters, from 106 cities throughout Europe. The bike counters allowed the researchers to measure the variety of cyclists citywide, not simply on the new bike paths. They analyzed the variety of cyclists from March via July and located that in cities that had added bike lanes, biking elevated 11 p.c to 48 p.c greater than in cities that had not added bike lanes.

The researchers discovered that the improve held when controlling for climate and modifications in public transit provide and demand.

Bicycles, in contrast to automobiles, don’t emit greenhouse gases. Matthew Raifman, a doctoral scholar in environmental well being at the Boston University School of Public Health, present in a separate study that investments in infrastructure for biking and strolling greater than paid for themselves as soon as the well being advantages had been taken into consideration.

“They increase our physical activity and reduce levels of greenhouse gas emissions and improve air quality, which all have impacts on health,” Mr. Raifman mentioned.

Mr. Kraus cautioned that his research’s findings had been distinctive to the pandemic, as public well being officers inspired biking to cut back the threat of coronavirus transmission and cities throughout the world added bike infrastructure to their streets. But it might not be a stretch to think about that extra folks may preserve driving bikes as soon as the pandemic ends.

Research on transit strikes has proven that forcing folks to experiment with new routes and modes of transit can result in new routines.

“There’s indications from mobility behavior research that as soon as you find another way of getting around, then you might actually stick to it,” Mr. Kraus mentioned. “So I’m confident that if you keep the infrastructure, that people will continue cycling.”
