Wireless 911 Call Routings Using Population Weighted Address Points
Track: Computer Aided Dispatch and 911
Authors: Li Zou

Wireless 911 call routing determines which Public Safety Answering Point (PSAP) to route cellular 911 calls. Two processes were developed to improve routing when a phone’s cell tower sector with multiple PSAPs. Primary assignment uses population weighted address points, and secondary validation uses wireless 911 call hotspot analysis. These applications have improved routing assignments and reduced both call transfers and response times. The process uses ModelBuilder and Python scripts.
