A Wonkish Plan To Prevent Car Accidents

Nicole Gelinas explores Bill de Blasio’s Vision Zero initiative, which aims to end traffic fatalities in New York City:

The inspiration behind the plan, which reinforces and expands on efforts by Michael Bloomberg’s administration, comes from Sweden’s use of innovative road design and smart law enforcement, which has reduced overall traffic fatalities in Stockholm by 45 percent—and pedestrian fatalities by 31 percent—over the last 15 years. When a child runs after a bouncing ball into a residential street and a speeding car strikes and kills him, the Vision Zero philosophy maintains, the death shouldn’t be seen as an unavoidable tragedy but as the result of an error of road design or behavioral reinforcement, or both. We already think this way about mass transit and aviation. These days, a plane crash or a train derailment is never solely explained by human error (a train conductor falling asleep, say); it also is a failure of a system that allowed a mistake to culminate in disaster.

Of course, engineers and regulators can’t eliminate all injuries and deaths; but by applying rigorous, data-based methods, they can cut down on them dramatically. …

New York City has already come a long way in reducing traffic fatalities, it’s important to recognize. Last year, New York suffered 288 crash deaths, including 170 pedestrians. That sounds bad, and it is, but in 1990, New York had 701 traffic deaths, with 366 pedestrians killed. And 20 years before that, the city saw nearly 1,000 traffic deaths in a single year; it wasn’t unusual to lose 500 pedestrians annually. New York’s current traffic-fatality numbers compare favorably with other American big cities. An Atlanta resident is more than three times more likely to die in a traffic crash (adjusted for population); a Los Angeleno faces twice the risk. But New York remains behind—in some cases, far behind—other global cities in this area of public safety: Paris, London, Hong Kong, and Tokyo are all less dangerous. A citizen of Stockholm—the gold-standard metropolis for traffic safety—faces just a third of a New Yorker’s risk in dying by vehicle. Last year, the Swedish city, with a population of 900,000, suffered only six traffic deaths. The Gotham equivalent would be 60 such fatalities—not nearly five times that number.
