For context, here are the current options for W. Main St.
Below is the letter I wrote to Council today:
Do bike lanes make New York City streets safer?
Yes, very much so. Bike lanes bring along with them safety improvements for the entire street and every street user — not just for people riding bikes. According to the DOT’s Pedestrian Safety Study and the most recent Sustainable Streets Index, streets with bike lanes have about 40 percent fewer crashes ending in death or serious injury, and that’s for all street users: drivers and pedestrians included. For example, after a parking-protected bike lane was installed on Manhattan’s Ninth Avenue, all traffic-related injuries dropped 50 percent. Injuries to pedestrians dropped 29 percent and injuries to cyclists dropped 57 percent.
For example, protected bike lanes include pedestrian refuge islands in their design, which shorten the crossing distance of wide avenues for people on foot. Protected bike lanes typically include priority left turn lanes and signals, which help to improve vehicle flow and deter failure to yield to pedestrian violations — a common reason for pedestrian injury on our busy streets.
Building a bike lane is not just for bicyclists. Bike lanes are one way to realize a ‘complete street,’ or a street that recognizes and keeps safe all [citizens] who use it.
Do more bicyclists on the street make it safer to ride a bike?
Yes, much safer. Intuitively, bicyclists know that it feels safer to ride a bike when there are other cyclists on the street with you. In 2003, researcher Peter Jacobsen published a groundbreaking report that confirmed bicyclists’ intuition to be based in scientific fact. The “safety in numbers” effect identified by Jacobsen’s research is this: The more bicyclists there are on the streets, the safer they are. The phenomenon can be attributed to a variety of factors, such as drivers’ increased familiarity seeing bicyclists on the street or street improvements, like bike lanes, that often accompany a growth in bicycling.
Data from a wide range of cities shows that every time the number of bicyclists is tripled, the driver-bicyclist crash rate is cut in half. The “safety in numbers” effect is happening in New York City as we speak, as documented by the DOT’s Cycling Safety Indicator. We have never had so many cyclists on the streets, and yet it has never been safer to ride a bike. Bike lanes, which do a lot to encourage cycling, are helping to add to this important “safety in numbers” effect on NYC streets.
In Australia, several different researchers have studied mandatory helmet laws — looking at the lives saved by helmets, the fact that biking is now more dangerous because there are fewer bikes on the road, the actual costs of buying helmets and enforcing the laws, and the massive health costs of having fewer people biking in a country that’s battling obesity — and concluded they do more harm than good.
