SAFETYChapter 2The Science of SafetyDOT’s concerted work to re–engineer streets with above–average crash histories, to meet community concerns abouttraffic safety and to meet its own strategic goal of reducingtraffic fatalities each year relies on ongoing and painstakinganalysis. NYCDOT collects and analyzes more informationabout the causes of traffic deaths and injuries than everbefore, and applies the agency’s resources to develop site–specific responses to that information.Data and design analysis have been key factors in DOT’ssuccess in pushing traffic deaths to historic lows, anddrives safety policy and projects to an unprecedenteddegree. The main effort sustains ongoing analysis ofthe highest–crash corridors and intersections so thoseareas can be addressed by DOT’s traffic safety experts andengineers. This work also focuses resources on particulargroups of at–risk pedestrians. The Safe Streets for Seniorsand Safe Routes to Schools programs described inChapter 1 are based on crash statistics that identifyand address safety problems experienced by specificvulnerable groups.TRAFFIC FATALITIES (2008–2012) TRAFFIC INJURIES (2007–2012)Motor VehicleOccupants24%Pedestrians30%Pedestrians56%Motor VehicleOccupant57%Motorcyclists13%8%7%5%BicyclistBicyclistsMotorcycleSustainable Streets: 2013 and Beyond33
