How to measure risk and improve safety for cyclists and pedestrians — the New York City edition

Following our post earlier this month, How to measure risk and improve safety for cyclists and pedestrians, we got some questions about how this analysis might apply in other large cities with Vision Zero programs.

We ran the same analysis on New York City, where we’re headed next week for the Vision Zero Cities conference. Here’s what we found. Thanks to Erik for the analysis.

The red hexagons indicate areas where more than 1 in 1,000 intersection crossings resulted in a collision in 2018. Priority Bicycle Districts are neighborhoods “with comparatively high numbers of cyclist KSI (Killed or Seriously Injured) and few dedicated bicycle facilities” and which have been prioritized for bike network expansion, according to NYC DOT. That dataset is available on the city’s Open Data Portal.

These districts represent 14% of the City’s bicycle lane network and 23% of cyclist KSI. As the map suggests, they do cover some significant areas of collision risk, although there are large areas of Queens and the Bronx that have similar concentrations of risk.

If you’re working on a Vision Zero plan or would like to learn more about volume-adjusted safety measurement, please get in touch. If you’re going to be at Vision Zero Cities in New York this week, let’s connect in person.
