This research addresses operational disconnects and knowledge gaps related to traffic data collection in rural areas by developing a low-cost 3D-printed and open-source traffic counter (CTRA). Conventional pneumatic tube-based systems, which are still in use by transportation agencies across the United States because of their affordability, simply do not work on gravel roads and have difficulty counting non-motorized users and differentiating non-traditional vehicles from conventional motor vehicles. CTRA was developed and field tested at the University of Alaska Fairbanks and designed to provide a video-based data collection system that overcomes the limitations of other traffic counting devices. A count rate of 100% was achieved during the calibration process. Other than electronic hardware, most pieces of hardware can be printed on a 3D printer to form a simple and robust case and mounting system and only straps are needed to secure the counter to a fixed object. Because of its relatively simple and affordable design, CTRA could also be used for STEM and educational activities in schools and other related programs.
