CrashStat Upgrade Provides Interactive, Up-To-Date Street Safety Data

Transportation Alternatives launched an updated version of its CrashStat website today, providing a wealth of new data about street safety in New York City and where pedestrians and cyclists are most at risk. The upgrade adds four years of geo-coded data about traffic injuries and fatalities, a smoother interface, and a wealth of interactive features.

More than 13,000 pedestrians and cyclists are injured or killed by motor vehicles in the city every year, according to state DOT data, and CrashStat puts information about those crashes at New Yorkers’ fingertips. If you want to know which streets in your neighborhood are most in need of safety fixes, CrashStat lets you to locate the most dangerous intersections and corridors. Before this update, the most recent data on file in CrashStat was from 2005; the new version includes information up to and including 2009.

The new version also allows users to see who is affected by unsafe streets and what’s causing pedestrian and cyclist injuries. You can filter the crash information to see where children or seniors are particularly vulnerable, for instance, or to highlight the crashes caused by excessive motor vehicle speeds or distracted driving. Users can look at safety stats by legislative district, police precinct or neighborhood, helping activists marshal data specific to their area.

“By revealing where and why motor vehicle crashes occur, CrashStat gives all New Yorkers the information they need to demand better enforcement of our traffic laws,” said TA director Paul Steely White in an announcement about the upgrades. “This is critical to changing behavior on our streets.”

According to the new CrashStat data, the most dangerous intersection for pedestrians in the city is the corner of Park Avenue and 33rd Street, where 163 crashes injured pedestrians from 1995 through 2009. However, safety improvements at that intersection put into place in 2008 reduced total injuries at that intersection by 74 percent.

Crash data is also supposed to be provided monthly by the NYPD under a law passed by the City Council last winter. City Council Member Jessica Lappin’s “Saving Lives Through Better Information” bill required the police to provide regularly updated crash data searchable by intersection. The NYPD only put its first month’s worth of crash data online last night in response to questioning by the New York Daily News.

  • Nobel prize to be shared among whoever at TA first conceived of Crashstat, and to TA in general.  Seriously, this is a tremendous public good that none of the entities that should be responsible for such information ever provided.

    Big ups to John Kaehny who go crashstat going ten years ago. T.A.’s mike Infranco and Renee Fidz have been burning the midnight fry oil to launch this latest iteration.

  • Ian Turner

    Can we use this new data to compute the average safety effect of new street treatments, such as bike lanes, citywide?

  • Komanoff

    Can Noah K or T.A. add a link to the (purported) NYPD data so we can see what if anything was provided in response to that Daily News query?

  • Anon

    really slow…and a bit confusing

  • crash data

    The NYPD crash data is here:

    If some enterprising person would like to have a hand at parsing this data into a more useful format, go to it!

  • as usual, T.A. is super helpful and trying to save our lives, while NYPD bogs the data down in complicated 100+ page format. Are the cops using a spreadsheet and then only giving out a PDF on purpose?

  • Vacca-uous

    Despite the NYPD’s failure to provide these stats with reasonable timeliness or in a remotely usable format, as well as the failure to enforce street safety in any meaningful way, I’ll be sure to lambaste TA staffers when they come before my committee to testify against Norman’s or Lew’s bike-lane-stalling legislation.


Crashstat 2.0 Reveals NYC’S Most Dangerous Intersections

Crashstat shows Fordham Rd. in the Bronx to be one of the most dangerous streets in New York City. For years, Livable Streets advocates have pushed New York City government to make citywide pedestrian and cyclist crash data more accessible to help civic groups and policy makers make more intelligent street design improvement decisions. Rather […]

“Bike Bedlam” Fact Check: NYC Bike-Ped Injuries Drop From Low to Lower

Editor’s note: Streetsblog has retracted this post. The information on bike-on-ped crashes is not accurate. Read the full correction for an explanation of how we acquired the erroneous data and how we determined it was incorrect. Pedestrian injuries sustained citywide in collisions with bicyclists pale beside the more than 10,000 pedestrian injuries and deaths sustained […]

NYPD Goes Out of Its Way to Obscure Street Safety Data

It took several months and some needling from the Daily News, but NYPD this week finally complied with a new city law requiring the department to release data on traffic crashes. Unless you have the time and resources to comb through and analyze hundreds of pages of rows and columns, however, good luck getting much […]

Eyes on the Street: Another Curb-Jumping Motorist on the UWS

Another day, another motorist barreling onto a New York City sidewalk. Reader Liz Patek sends this shot of the crash aftermath at Columbus and 72nd Street yesterday evening, where a van driver, apparently heading east, jumped the curb and crashed into a light pole. The tally on CrashStat reveals that 20 pedestrians and eight cyclists […]

In a Collision? Share Your Experience on TA’s CrashStories Website

Today, Transportation Alternatives is launching CrashStories, a new website where pedestrians and cyclists can report crashes or near-misses with motor vehicle drivers on an interactive map. Developed by Hunter College city planning graduate student Aaron Fraint, the project aims to fill gaps in official data sources and offer a place for crash victims to be heard. Data mapped […]
