The author of the I Quant NY blog profiles an excellent use of of NYC’s Open Data portal in a post detailing how the city has been systematically ticketing legally parked cars:
As of late 2008, in NYC you can park in front of a sidewalk pedestrian ramp, as long as it’s not connected to a crosswalk. It’s all written up in the NYC Traffic Rules, and for more detail, take a look at this article.
Is it a problem that drivers don’t realize that there are some extra parking spots they are now allowed to park in? Not so much. But, I’ve got a pedestrian ramp leading to nowhere particular in the middle of my block in Brooklyn, and on occasion I have parked there. Despite the fact that it is legal, I’ve been ticketed for parking there. Though I get the tickets dismissed, it’s a waste of everybody’s time. And that got me wondering- How common is it for the police to give tickets to cars legally parked in front of pedestrian ramps? It couldn’t be just me…
In the past, there was not much you could do to stop something like this. Complaining to your local precinct would at best only solve the problem locally. But thanks to NYC’s Open Data portal, I was able to look at the most common parking spots in the City where cars were ticketed for blocking pedestrian ramps. It’s worth taking a moment upfront here to praise the NYPD for offering this dataset to begin with. Though we are behind on police crime data in the city, we are ahead in other ways and the parking ticket dataset is definitely one of them.
The response from the NYPD that the author received speaks volume (an admission of mistake and a promise to get it right with the proper training):
Mr. Wellington’s analysis identified errors the department made in issuing parking summonses. It appears to be a misunderstanding by officers on patrol of a recent, abstruse change in the parking rules. We appreciate Mr. Wellington bringing this anomaly to our attention.
The department’s internal analysis found that patrol officers who are unfamiliar with the change have observed vehicles parked in front of pedestrian ramps and issued a summons in error. When the rule changed in 2009 to allow for certain pedestrian ramps to be blocked by parked vehicles, the department focused training on traffic agents, who write the majority of summonses.
Yet, the majority of summonses written for this code violation were written by police officers. As a result, the department sent a training message to all officers clarifying the rule change and has communicated to commanders of precincts with the highest number of summonses, informing them of the issues within their command.
Thanks to this analysis and the availability of this open data, the department is also taking steps to digitally monitor these types of summonses to ensure that they are being issued correctly.
