The New York Times reported this week on a decision targeting cyclists that might surprise some: “In the wake of two pedestrian deaths caused by collisions with bicycles, Central Park has lowered the speed limit for cars and bicycles to 20 miles per hour from 25, while reconfiguring intersections with especially heavy foot traffic.” Though the announcement mentioned cars it was mainly focused on bikes since large sections of the park are closed to motor vehicles at any given time (on weekends the entire park is off-limits to cars except for a couple of car-only passages that are largely below ground level and mostly invisible to other park users).

The speed limit change is part of “Vision Zero,” a program of safety improvements touted by New York Mayor Bill de Blasio with the goal of eliminating pedestrian deaths citywide. Earlier this year the Times reported that as part of Vision Zero police had stepped up speed limit enforcement in the park, at one point issuing “tickets to 103 bicyclists” in a single weekend, though that level of enforcement is not the norm. The program’s most visible element has been the lowering of the speed limit on most of New York’s streets from 30 mph to 25 mph.

In both fatal accidents congestion appears to have been a major issue, according to the Times. One victim was struck by a cyclist who “said he had swerved to avoid other pedestrians.” The other involved “a 17-year old bicyclist dodging a pedicab.” The paper quotes the head of the Central Park Conservancy, the non-profit group that handles day-to-day operations of the park, saying “There’s no question: Slower traffic will mean a safer park.”

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.

It is no secret that Portland has a reputation as one of America’s most bike-friendly cities, but the census bureau now has the data to prove it. According to a recent article in The Oregonian, since 2000 biking to work “has shown the largest percentage increase among all commuting modes” nationally. Portland leads the way with a significantly higher percentage of bicycle commuters than the national average.

Nationally about 786,000 people get to work using bicycles, according to the paper, up from 488,000 in 2000 (the data is for 2012, the latest year available). That’s only about one percent of commuters nationwide, but “within the Portland city limits the number has nearly tripled since the 2000 census… In fact, Portland leads all large cities with a bicycle commuting rate of 6.1 percent.”

According to the newspaper, local activists welcomed the news, but also warned about “complacency.” The head of the Bicycle Transportation Alliance called for “bolder steps” by the city to prevent Portland bicycle accidents so that commuters will feel safer. The article specifically cites initiatives to create “buffered bike lanes” – a move which often requires the removal of parking spots or one auto lane along busy streets that double as important bike commuter routes. It also cites “a long-delayed $4 million bike sharing system, which still lacks a sponsor.” Once implemented, the bike share program is also expected to increase bike commuter numbers. The Oregonian concludes by noting that “Portland’s strategic bike plan calls for 25 percent of all trips in the city to be made on a bike by 2030.”
