Research Bolsters Case for Cycle Tracks While AASHTO Updates Guide

from Streetsblog New York City by Adam Voiland
For decades, dueling camps of cycling advocates have feuded about how to best accommodate riders. Some have pushed for the construction of Dutch-style cycle tracks, arguing that separated lanes make bicycling safer and less intimidating, while others have insisted such infrastructure isolates riders and makes cycling more dangerous than simply remaining within the flow of traffic.
Though the debate has grown bitter at times, neither group has had much in the way of rigorous peer-reviewed research to argue their case through the years. However, in the last decade a small but energetic group of academics has started to publish regularly on the topic.
The latest salvo, published online in February and in the current edition of Injury Prevention, comes from Harvard University researcher Anne Lusk. Her study compares crash rates at six cycle tracks in Montreal to nearby streets that had no bicycle facilities, and bolsters the argument that cycle tracks are safer. Lusk found that relative risk of injury was 28 percent lower on cycle tracks compared to the on-street routes.
In addition, she found that about 2.5 times as many cyclists used the cycle tracks than the on-street routes. The finding agrees with the conclusions of a number of other recent studies that show protected bicycle lanes improve safety and help attract new riders.
