To Make NYC Streets Safer, Focus on the Cause of 98 Percent of Harm

On Wednesday, Manhattan Borough President Gale Brewer spoke in support of legislation that would create a “bicycle safety task force.” The language of the bill, introduced by Council Member Rosie Mendez at Brewer’s request, says the task force would make recommendations for improving bike infrastructure. But in testimony to the council transportation committee, Brewer suggested the panel would also provide a venue for people to gripe about cyclists.

“My office fields nearly daily complaints, many from seniors, who experience near misses with bikers, many of [whom] are breaking the law in some fashion,” Brewer said.

Earlier in the week Mendez staffer Matt Viggiano said basically the same thing to AMNY: “We have a lot of seniors who have called our office with complaints when cyclists don’t follow the rules of the road, and present dangerous conditions for pedestrians.”

There’s no way to pinpoint the extent of the problem described by Brewer and Viggiano. The city does not track near-collisions between cyclists and pedestrians, just like it doesn’t track near-collisions involving motorists or the actual incidence of traffic law-breaking. But for the past few years the city has collected data on reported collisions between people biking and walking. The numbers show that targeting bikes can’t achieve major gains in pedestrian safety, because nearly all pedestrian injuries and deaths are caused by motorists.

DOT recently released 2014 figures on cyclist-pedestrian collisions [PDF] reported to NYPD. People on bikes struck and killed three NYC pedestrians last year, according to DOT, and injured 305 people walking. By comparison, motorists killed 134 pedestrians in 2014, and injured 10,981. So last year cyclists were accountable for just over 2 percent of pedestrian deaths, and less than 3 percent of injuries. And that year was an outlier for fatalities.

From 2000 through 2014, cyclists killed 11 people in NYC, while motorists killed 2,425 pedestrians, making cyclists accountable for .4 percent of deaths over 15 years.

The city didn’t start releasing data on pedestrians injured by cyclists until 2011, and 2012 was the first data set to cover an entire year. Here’s what we know from the three full years of data we have.

From 2012 through 2014, cyclists injured 865 people walking, and drivers injured 35,454. Over the three years for which data are available, cyclists were accountable for just over 2 percent of pedestrian injuries. Note that these comparisons don’t account for the severity of injuries, which likely tends to be worse when people are struck by multi-ton motor vehicles than by someone on a bike.

We know that pedestrian safety and cyclist safety are fundamentally aligned. When DOT has redesigned streets with protected bike lanes, pedestrian injuries and deaths have dropped significantly. And when streets are designed for slower motor vehicle speeds, everyone is safer.

Inconsiderate and aggressive bike riding can be a problem, but it’s not a significant threat to public safety. Creating a task force that would function as a venue to complain only about bicyclists will distract from the vastly more urgent task of preventing deaths and injuries caused by dangerous driving.

    The greenway is amazing, but it doesn’t work for every trip. Bike lanes on the avenues are frequently blocked and stoplights are too close together to make them very fast (reduced green time for dedicated auto left turns across the bike lane exacerbates this).

    “42X as many vehicle miles traveled in NYC by bicycle as by motor vehicle:”

    You’ve got that the wrong way ’round. There are 42 times as many motor vehicle VMT as bicycle VMT in NYC.

    It’s a pity the crash data aren’t broken down by commercial cyclists versus commuter/recreational. That would either support or refute my hypothesis that commercial cyclists are disproportionately causing crashes. On the face of it, the theory makes sense in that these cyclists have an economic incentive to cut corners. It’s also supported by the common complaint of “reckless delivery guys”.

    Commuters also have an economic incentive to cut corners, if they’re paid by the hour or if they’re evaluated in part on timeliness.

    As for the common complaint of “reckless delivery guys,” I don’t often claim racism but I suspect it’s simply racism.

    The Queens blvd underpasses will be great places to give free breakfast to bikers like yourself.

    It is good to be concerned about pedestrian deaths but we shouldn’t let that blind us to a better measure. Deaths automobile passengers and drivers are important as well.

    It would be better to look at how many people are killed by cyclists vs how many people are killed by drivers. It is nearly impossible for a cyclist to injure someone in an automobile.

    When looking at total deaths caused by transportation, the percentage caused by drivers would be waaaay higher than the 97.6% figure cited here. In that context, the danger of automobile centric city design is more accurately portrayed.


DOT and TA: “Bike Safety Task Force” Won’t Make Biking Safer

Okay, someone literally just compared #bikenyc to terrorists @NYCCouncil. Wow! — Joanna Oltman Smith (@jooltman) December 2, 2015 A proposed “bike safety task force” met with resistance from city officials and safe streets advocates at a City Council transportation committee meeting this morning. DOT joined Transportation Alternatives in opposing Intro 219, which would create a […]

Bike Lane Made Columbus Avenue Safer, and UWS Residents Noticed

The Columbus Avenue bike lane is both safe and popular, according to two assessments released at a meeting of Community Board 7 last night. Representatives from the Department of Transportation presented data showing that the street redesign reduced the number of crashes on the street by 34 percent, while 73 percent of Upper West Siders […]

Can the New York City Council Wrest Crash Information From NYPD?

City Council Member Gale Brewer wants to open up traffic data to improve conditions for pedestrians and cyclists on Manhattan’s West Side, a campaign that could lead to safer streets across the boroughs. Because crash info remains hidden from the public, the only civilians who see the results of unsafe conditions are witnesses. In February, […]
