Keep this in mind the next time a high-profile train crash generates more press coverage than a year’s worth of car wrecks: Despite the media sensationalism and overwrought regulatory responses that follow such events, transit is already a lot safer than driving.
Looking at traffic fatalities per mile traveled in the U.S., analyst Todd Litman found that riding commuter or intercity rail is about 20 times safer than driving; riding metro or light rail is about 30 times safer; and riding the bus is about 60 times safer. Factoring in pedestrians and cyclists killed in crashes with vehicles, the effect is smaller but still dramatic: the fatality rate associated with car travel is more than twice as high as the rate associate with transit. Litman’s study was recently published in the Journal of Public Transportation [PDF].
Litman notes that most transit travel involves some walking or biking, which carry a relatively high risk of traffic injury. But those risks are mostly offset by the health benefits of physical activity. Living in a place with good transit has safety benefits as well: Litman cites research showing that cities with higher transit ridership rates tend to have lower per-capita traffic fatality rates.
