Montreal's cycle tracks attract 2.5 times as many cyclists as comparable streets with no bike lane, and have lower injury rates, a new study shows. Image: Bicycle Canberra
Researchers at Harvard have delved into the relative safety of separated bike lanes versus riding on the road. In case you had any doubts, cycle tracks are safer.
Dr. Anne Lusk at Harvard’s School for Public Health studied injury rates on cycle tracks in Montreal, comparing them to injury rates on comparable streets with no bike lane. Her study, published in the journal Injury Prevention, found not only that cycle tracks attracted 2.5 times as many cyclists, but also that injuries were generally more rare.
Not a terribly surprising result. But it’s an important one because the most influential guidelines for American traffic engineers discourage the use of cycle tracks.
