Using Spatial Analysis to Prioritize Pedestrian Safety Interventions and Describe Geographic Trends in Pedestrian Safety

Transportation Research Board Annual Meeting 2010, Paper #10-4049

“This paper illustrates the application of several geospatial and analytical tools to the problem of prioritizing pedestrian and other safety improvements in New York City, describes the process used to analyze crashes in New York City, then describes the application of spatial analysis to the problem of contextual project evaluation. An analysis was conducted of the change in pedestrian crashes from the 1992-1996 period to the 2002-2006 period using the kernel density technique. Pedestrian crashes in New York City were found to have decreased in severity and frequency from the mid-1990s to the mid-2000s, but these changes were not evenly distributed across New York City Low-density residential and commercial areas did not experience consistent improvements, except at the locations of major NYCDOT safety implementations, e.g. Queens Boulevard.”
