Investing in a network of fully separated bike lanes could save cities huge sums in the long-term. But too little investment in wimpy infrastructure could actually decrease enthusiasm for cycling.
For every dollar spent to build new separated bike lanes, cities could save as much as $24 thanks to lower health care costs and less pollution and traffic, according to a from researchers in New Zealand.
"At the moment in most car-dominated cities, it’s easy to justify spending transport money on new roads as a response to increasing car use, despite the negative impacts this has on the environment and people’s health now and in the future," says lead authorAlexandra Macmillan. "We wanted to explore some policy choices that were realistic, affordable, transformative and healthy."
