Using Security Cameras to Count Transit Passengers

The Institute for Transportation Research and Education at North Carolina State University performed research to determine if transit vehicle security camera footage could be paired with Autoscope software to automatically count transit passenger boardings. The research was limited to community transportation systems vehicles. The Autoscope software allows analog footage to be analyzed using the strategic placement of detectors and functions of detectors to determine where the background image changes. After attempting multiple detector placements in multiple vehicle types with multiple camera configurations, the results show promise that algorithms can be set up in a cost effective manner for counting passenger trips repeatedly on the same vehicle, but less promise that a standard algorithm can be developed that will accurately count passenger trips even on the same vehicle type with similar camera configurations. Because this research stems from a specific need for North Carolina Department of Transportation (NCDOT) to be able to validate passenger trip reporting from transit systems, two sampling plans are suggested as well as expected costs. One involves manual counts using spot-checks of data and the other involves more robust analysis of a single vehicle from each transit system operating deviated fixed route service.
