Abstract:Through academic research and direct communications with transportation agencies, this project surveys new roadside technologies that can assist in efforts for detecting pedestrians. Reasons for using such technologies include traffic operations enhancements, safety improvements, planning, benchmarking, and eventual connected vehicle integrations. Traditional technologies and many new product offerings are identified. Results of surveys and interviews show that most practitioners use video-based technologies, but thermal imaging, LiDAR, and combinations of these technologies with video are gaining attention. The expense of technologies and their suitability for use in specific environments are important considerations in choosing products. Details about ongoing cost structure and data ownership are also important to analyze, including products that require a recurring subscription to a cloud-based data processing service. Some agencies have designed their own systems or data processing schemes to avoid expenses required by commercial providers. This project delivers a simple decision support framework that assists in identifying products and technologies most appropriate for a set of requirements.
