This report documents the research conducted by NCHRP Project 07‐19(02), Methods and Technologies for Pedestrian and Bicycle Volume Data Collection: Continuation. This continuation project tested and evaluated automated count technologies that capture pedestrian and bicycle volume data, focusing on technologies that came onto the market too late to be included in the Phase 1 research (NCHRP Project 07‐19). The report presents combined results for a range of technologies tested by both the Phase 1 research and the continuation research (Phase 2). The research evaluated automated nonmotorized count technologies in different settings, including ranges of temperature, varying weather conditions, mixed traffic conditions, mixed travel directions, and facility types (e.g., roadways, multiuse paths), to determine their accuracy and reliability in different contexts. This report documents the research 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 careful site selection plays an important role in the ultimate accuracy of the collected count data. It is also critical for practitioners to calibrate the counters they install at specific sites to obtain the most accurate and reliable results.
