An article published earlier this month by Al Jazeera America looks at a new academic study focusing on the costs and benefits of bike lanes and other publicly-funded spending on cycling infrastructure. Living in Portland, a city often cited as one of the most bike-friendly in North America, its findings are not likely to be particularly controversial. Still, they are a useful reminder of how bike riding benefits the community at large and not just cyclists themselves.
The study (see link below) was published in Environmental Health Perspectives, an academic journal sponsored by the National Institutes of Health. It comes with the ponderous title “The Societal Costs and Benefits of commuter bicycling: Simulating the Effects of Specific Policies Using System Dynamics Modeling” but reaches, Al Jazeera reports, a fairly straightforward conclusion: “for every dollar spent on bike-related infrastructure, cities can receive anywhere from $6 to $24 in cost savings in the form of reductions to pollution and traffic congestion, as well as lowered health care costs from decreased traffic fatalities and increased exercise.”
Some of those conclusions may seem obvious to an audience here in bike-friendly Oregon, but they are a reminder that it is important to get the details of infrastructure right. More importantly, in focusing on the big picture – by, for example, citing long-term benefits such as lower health-care costs the study is especially useful.
