Introduction: In New York City (NYC), nearly 4,000 residents are injured and more than 250 residents are killed due to traffic collisions each year1.  According to NYC government, collisions injure or kill some City residents every two hours2.  In response to the high injury rate, the City has taken a number of initiatives to mitigate the volume of injuries, including, expanding enforcement against speeding and yielding to pedestrians, harsher penalties for dangerous drivers, and new street designs that improve safety. The questions for this project are to find out tendency of fatalities due to road accidents in NYC for period from 2009 to 2016, localize some high-risk locations for 5 boroughs for 3 major groups – pedestrians, bikers, and motor vehicle occupants, and explore what are the changes for these locations. To answer the stated questions, I’m going to analyze a data provided by Department of Transportation (DOT) of NYC.
