NYC Opens Traffic Crash Data -- Finally

Wednesday, May 07, 2014 - 02:59 PM

After years of prodding from safe streets advocates, the New York City Council, and the tech community — not to mention reporters — New York City has finally released comprehensive traffic crash data.

“This is amazing, and more than what we were expecting," said coders Noel Hidalgo and John Krauss in a joint statement. "The geocoding and integration with the data portal are unexpected and *extremely* pleasant surprises.”

The data went live earlier Wednesday in preparation for this year's BigApps, a four-month long competition that leverages technology to solve civic problems. It represents all collisions for which NYPD completed an MV-104 report dating back to July 1, 2012, and can be downloaded in a variety of formats. As of right now, it contains 329,018 separate entries.

Previously, the NYPD released crash data on a monthly basis (with big lags) in PDF format. At a City Council hearing last year, Hidalgo told the council: "Because of poor, inconsistent, and non-existent crime and crash data, creating tools to make safer streets is next to impossible."

As an example, here's a photo of 2012 crash data WNYC received last year after filing a Freedom of Information Law request with the NYPD:

Opening traffic crash data also fulfills a key component of Mayor Bill de Blasio's Vision Zero plan. In a newly-released video for BigApps, de Blasio says: "My big idea is to eliminate traffic fatalities in New York City."

Noah Budnick, the deputy director of Transportation Alternatives, was thrilled by the city's move. "Having the data and being able to analyze it is a very important first step to figuring out what the problems are and how to solve them," he said. "It's almost an epidemiological approach" to preventing traffic crashes.

Even this new and improved data, however, lacks some specificity. The ages of crash victims aren't included, for example, and it's not clear whether the latitude and longitude pertains to the actual scene of the crash or the nearby intersection. But "this is a great start," said Budnick. "It's an amazing step, and hopefully the start of a civic conversation. This is not the end. This is the beginning."

One quick clarification, John Krauss should be attributed to the second paragraph. I should have made it clear in our initial statement. http://blog.betanyc.org/post/85050036452/on-the-release-of-nypds-crash-data-and-nyc-bigapps

"It's almost an epidemiological approach", he said. If the trend line for fatalities and for injuries has been going down for years and decades, how is this now considered an epidemic?

Seems to be a continuation of the Bloomberg 'Data Is King' approach.

Mel, The data above can actually be sorted and searched interactively. Give The Internet a week or so and I can pretty much guarantee someone will visualize it for you too.

Raw data is great because it doesn't have the PR glamour usually associated with NYC press releases.

If it contains 330,000 separate entries, what good is it. No human can make sense of 330,000 entries that are not compiled, organized, meaningful. Could this have been done on purpose? Or is this just the kind of work our city does - compiles data that no one ever looks at or makes any sense or use of.
