The number of fatalities on city streets fluctuates each year, and there does not appear to be a clear trend, figures from the city’s Department of Transportation show.

In 2009, 12 cyclists died in crashes. In the years since, the figure has been as high as 24 in 2017 and as low as 10 last year.

What is the city doing about this?

Today Mr. de Blasio is scheduled to unveil what he is calling a “green wave” bicycle plan.

It includes $58.4 million in investments over five years and a commitment to annually build 30 miles of protected bike lanes. (As Streetsblog has reported, Staten Island has “just 100 yards of protected bike lane on a single road.”)

The police will also pursue drivers at “crash-prone intersections” for speeding, blocking bike lanes and failing to yield, according to the plan. (In the last few weeks, the police said they have given more than 7,000 summonses to drivers for failing to yield and blocking bike lanes. )

The city will also install 2,000 bike parking spaces annually and look into creating a “high-capacity bicycle parking system.”
