Cities that build protected lanes for cyclists end up with safer roads for people on bikes and people in cars and on foot, a new study of 12 large metropolises revealed Wednesday.
Researchers at the University of Colorado Denver and the University of New Mexico discovered cities with protected and separated bike lanes had 44 percent fewer deaths than the average city.
“Protected separated bike facilities was one of our biggest factors with being associated with lower fatalities and lower injuries for all road users,” study co-author Wesley Marshall, a University of Colorado Denver engineering professor, told Streetsblog. “If you’re going out of your way to make your city safe for a broader range of cyclists … we’re finding that it ends up being a safer city for everyone.”
Marshall and his team of researchers analyzed 17,000 fatalities and 77,000 severe injuries in cities including Denver, Portland, Dallas, Seattle, San Francisco, Kansas City and Chicago between 2000 and 2012. All had experienced an increase in cycling as they built more infrastructure.
Researchers assumed that having more cyclists on the street was spurring drivers to slow down — a relic of a 2017 study that found that cities with high cycling rates had fewer traffic crashes. But it turned out that wasn’t the case.
Instead, researchers found that bike infrastructure, particularly physical barriers that separate bikes from speeding cars as opposed to shared or painted lanes, significantly lowered fatalities in cities that installed them.
