Department of Transportation. Office of ResearchUnited States. Federal Highway AdministrationUS Transportation CollectionThe objective of this project was to develop a portable automated system to collect continuous video data on pedestrian and cyclist behavior at midblock locations throughout the metro Atlanta area. The system analyzes the collected video data and automatically identifies and characterizes the number of pedestrians and their behavior at midblock locations (specifically, their crossing locations and frequency). The system is designed to be portable to support data collection in multiple locations. Some of the pertinent conclusions from this study are: 1) A portable trailer video recording system was implemented 2) Field testing of pedestrian detection algorithms yielded accuracy of pedestrian detection between 85% and 90% 3) Final output from system tests resulting in pedestrian counts with up to 97% accuracy
