Visibility and conspicuity, human factors, and accident reconstruction
Mr. Suway is a licensed Professional Mechanical Engineer, an ACTAR accredited accident reconstructionist and human factors expert and has been working in these fields since 2008. Mr. Suway holds a Master of Science degree in Civil Engineering with a specialty in Transportation Safety from the George Washington University through the National Crash Analysis Center (NCAC), and he holds a Bachelor of Science in Mechanical Engineering from Bucknell University. He has testified as an expert in Accident Reconstruction and Human Factors including complex visibility and conspicuity analyses.
He has extensive experience conducting complex 3-dimensional accident reconstructions and simulations. He performs mechanical inspections for component failure and driveability issues in light-duty passenger vehicle, heavy trucks, buses and other equipment.
Mr. Suway is qualified to download and analyze all types of Event Data Recorders and is certified in the download and analysis of Bosch Crash Data Retrieval (CDR) data.
Mr. Suway conducts and analyzes complex visibility and conspicuity analyses and recreations. These recreations allow for analysis of when or if pedestrians, vehicles or other objects are visible. Additionally, Mr. Suway creates Forensically Accurate Photographs and Video for demonstrative evidence.
Mr. Suway researches and analyzes human factors issues, such as perception-response times, typical human behavior, object detection, human perception, and product warnings and signage.
He has extensive involvement in research and has numerous peer reviewed publications and presentations through the Society of Automotive Engineers (SAE), Transportation Research Board (TRB), Human Factors and Ergonomics Society (HFES), and Enhanced Safety of Vehicles (ESV). Mr. Suway has published papers on crush stiffness coefficients of heavy commercial vehicles, tractor-trailer tire blowouts, brake characteristics of tractors, small overlap impact configurations, and 3-dimensional simulations. He has also conducted research and published on topics relating to visibility, calibration of night-time photographs and video, retroreflective DOT-C2 tape, driver detection distances, driver eye glances, responses to slow or stopped lead vehicles, and the visibility of stairs in low-light conditions.
Mr. Suway is a voting member on several SAE and American Society for Testing and Materials (ASTM) committees dealing with data collection and analysis and retroreflective sheeting and materials.
