The city went live with a major upgrade to NYPD’s crash data today. Information about traffic crashes was previously released via difficult-to-use monthly updates posted on the police department’s website. Now it’s available through a standardized feed updated daily on the city’s open data portal, allowing the public to sort crashes by time of day, street, zip code, and borough, as well as by the number of injuries and fatalities.
Later today EDC will be launching the BigApps competition, and Mayor de Blasio has asked NYC’s tech community to take on the issue of street safety. With this NYPD data upgrade, developers will have more flexibility to build useful tools for the public. A community board, for example, could receive an alert within 24 hours whenever there is a traffic injury or fatality within its borders.
“Up until now, New Yorkers haven’t had the opportunity to easily assess the relative safety of their street, the route their child walks to school, or their neighborhood at large,” said Transportation Alternatives Executive Director Paul Steely White in a city press release. “The Mayor’s announcement represents an important step forward to present crash data in a timely fashion that New Yorkers can view, understand and use, so that we can all make our city safer.”
“On first pass, this looks fantastic,” said John Krauss, who developed a map of crashes using the old data set. “This is amazing, and more than I was expecting.”
By opening the source data to the public, the city has essentially leapfrogged a City Council bill that would require NYPD to map its crash data. But despite the improvements, there are some remaining questions. The updated data goes back to July 2012, but NYPD has been publishing crash information since August 2011. The updated data adds geographic coordinates, making it easier to map the information, but they are tied to the nearest intersection, not the actual location of the crash. (NYPD has said it will work with the DMV to update crash forms to allow for more precise location data.)
