Today the Boston Cyclist's Union (BCU) launched their interactive Boston bike Crash Map, a mapping tool that I've been working on with them to help share and analyze bicycle crash data. They did all the hard work of getting the Boston Emergency Medical Services and Police Department to properly code and release the data---I just helped them clean it, geocode it and put it on a map.
Back in March and April of this year we asked Boston Emergency Medical Services (EMS) and the Boston Police Department (BPD) to separate bike and pedestrian crash data to allow us to see where bike crashes are happening. And to theircredit, each department quickly recognized the need and worked with us to meet it, partly by adding bicycle checkboxes to their incident report forms.
Now, not only do we have over six months of data to look at (May thru October 2010), but it's all plugged into an interactive Google mapcreated by Union member and volunteer Ben Sheldon. Thanks Ben! It will still be a year or two before we can have a large enough sample size to discern reoccurring patterns at particular intersections, but this first six-month glimpse of the data does give a sense of where crashes are happening in the city and a few other interesting things.
