Bike lanes not only protect cyclists from negligent drivers, they protect drivers and pedestrians too. A longitudinal study reveals that it’s not the cyclists which make the streets safer, rather it’s the infrastructure that separates cyclists from giant metal slabs that matter. Bike lane only made of paint did nothing to change the dangers of driving; rather, physical barricades protecting people from cars are what make the difference.
It’s simple: protected bike lanes = a safer city.
After analyzing traffic crash data over a 13-year period in areas with separated bike lanes on city streets, researches estimated that having a protected bike facility in a city would result in 44 percent fewer deaths and 50 percent fewer serous injuries than an average city.
In Portland, where the population of bike commuters increased from 1.2 to 7 percent between 1990 and 2015, fatality rates fell 75 percent in the same period. Fatal crash rates dropped 60.6 percent in Seattle, 49.3 percent in San Francisco, 40.3 percent in Denver, and 38.2 percent in Chicago over the same period as cities added more protected and separated lanes as part of their Vision Zero plans.
