This report documents and presents the results from NCHRP Project 07-19, Methods and Technologies for Pedestrian and Bicycle Volume Data Collection. This project tested and evaluated a range of automated count technologies that capture pedestrian and bicycle volume data. The focus of the study was to evaluate the technologies in different count settings, including ranges of temperature, varying weather conditions, mixed traffic conditions, mixed travel directions, and different facility types (e.g., roadways, multiuse paths), to determine their accuracy and reliability in different contexts. This report documents the project’s findings on the accuracy and consistency found for the different automated count technologies. It provides a complete account of the process used to select technologies for testing, identify test sites, and evaluate the effectiveness of the technologies. It is clear from the testing that it is critical for practitioners to calibrate and evaluate the effectiveness of the counters they install at specific sites to have the most accurate understanding of how well the counters capture non-motorized volumes under site-specific conditions.
