This report describes a GIS-driven investigation into the geography of pedestrian safety, especially related to seniors, and the causes of pedestrian-vehicular crashes in New York City. Particular attention is paid to pedestrians over the age of 65, who comprise 40% of pedestrian deaths in New York City. It reports on existing and emerging tools used to improve pedestrian safety in New York City, and describes several NYCDOT programs and projects that have been guided by this research, including the Safe Streets for Seniors program. This work and associated research are intended to lay the groundwork for broader pedestrian safety planning in New York City and to point the way to further research.
