According to a 2020 study by the Insurance Institute for Highway Safety and the Highway Loss Data Institute, protected bike lanes with heavy separation — those consisting of tall, continuous barriers or raised roadway surfaces — were associated with a lower risk of crashes.
In addition, studies show that bike infrastructure with more protected and separated bike facilities is significantly associated with fewer crashes resulting in cyclist fatalities. From 1990 to 2010, fatal crash rates in Chicago dropped by 38% by adding bike infrastructure to roadways, specifically lanes that were protected and separated, according to a 2019 study in Volume 13 of the Journal of Transport and Health.
