TA Rolls Out CrashStat Improvements

cs1.jpg
E. 33rd St. and Park Ave. was the city’s most dangerous intersection between 1995 and 2005.

Transportation Alternatives’ CrashStat 2.0 is now out of beta, with improvements in performance and functionality.

The most obvious change is that the data loads a lot faster, and the icons are cleaner. There are more data points, too: the map now features stats by borough as well as community district. And there are icons indicating community facilities like schools and hospitals.

Originally launched in 2004, CrashStat allows users to access official data on city pedestrian- and cyclist-involved crashes from 1995 to 2005.

Stats are now viewable by community district.

    Good work TA! The final touches on Crashstat 2.0 really make the difference.

  • Streetsman

    Interesting to see those stats conglomerated by community district. That could really show you which Community Board districts are most in need of traffic calming, based on what percentage of crashes results in injuries or deaths.

    For example, in Manhattan CB3 (shown), 98.2% of crashes resulted in injury, 1.8% resulted in death. I bet the fatality percentage is much higher for other CB’s across the city. Would be good to see a comparison.

    As a side note, I find these statistics positively chilling and it makes me sick to my stomach to throw the numbers around in conversation. 58 human lives were lost in CB3 over 10 years, simply as a consequence of being a pedestrian. That might be more than murders. If I were a member of CB3, lowering those numbers would be one of my top priorities.

  • Streetsman, the injuries and fatalities always add up to 100%, so that total must not include collisions that did not result in injuries or fatalities.

    For CB2 in Queens, we have 33/1772 = 1.86% of the injires being fatal, not that different from Manhattan CB3.

  • For CB11 in Eastern Queens, it’s 11/972 = 1.12%. Anyone calculate the effect size?

  • Streetsman

    Here’s a couple of very high ones:

    Bk CB15 (Sheepshead Bay) – 60 fatalities, 2.2%
    Bx CB10 (Throgs Neck) – 22 fatalities, 2.4%
    Q CB6 (Forest Hills) – 41 fatalities, 2.7%
    SI CB2 (Willowbrook) – 28 fatalities – 2.9%

  • Streetsman

    Two of those districts tend to be high because of known culprits – Queens Boulevard, Hylan Boulevard.

    But Nostrand Ave, Ocean Ave., and Ave. U in Sheepshead Bay are all death traps. That nabe needs some serious traffic calming.

    Dont worry streetsman Lew from Brooklyn is on the case bravely helping to move more cars on Ave. U.

  • Streetsman

    An average of 250 pedestrians a year are hit by cars in Brooklyn CB15, and 5 of them a year will die. It is outrageous.
