Ellen Szubski, Ph.D., is a human factors consultant at The Warren Group. She earned a Doctorate of Philosophy in Human Factors Psychology and a Master of Science in Applied Psychology from Clemson University. Ellen is also a Certified XL Tribometrist, a Certified Playground Safety Inspector, and a Certified Associate Human Factors Professional (AHFP).
Ellen worked in the Clemson Visual Perception and Performance Laboratory examining the factors contributing to the conspicuity of pedestrians and bicyclists in challenging road conditions, such as nighttime driving. She did her dissertation on “The Influence of Pedestrian Biological Motion on Time-To-Collision Estimates at Night”. Prior to entering the forensic field, Ellen planned and conducted experiments for a major bicycle manufacturer. She wrote and presented reports to stakeholders and product managers that improved and applied knowledge of bicycle conspicuity. She also conducted laser strike perception studies for the Department of Defense.
Ellen applies her experience in Human Factors to the analysis of crash investigations and other personal injury matters. These matters often include collisions involving vulnerable road users and drivers, driver distraction, and slips, trips, and falls. She utilizes her knowlegde of OSHA regulations, codes, and standards in her analysis of premises liability incidents and safety consulting.
Ellen is a current member of the Human Factors and Ergonomics Society (HFES) and its Forensic Professional Technical Group.
A 43-year-old man driving his small vehicle northbound in the right lane of a rural two-lane paved road, was on his way to his favorite hunting spot in the early morning. He had two passengers with him—one in his front passenger seat and one in his back left seat. It was dark outside, and the […]
An alarming 6,516 pedestrians were killed, and 54,769 pedestrians were injured as a result of traffic crashes in 2020 (NHTSA, 2022). A large majority (77%) of these pedestrian fatalities occurred in low luminance conditions such as nighttime while only 20% occurred in daylight (NHTSA, 2022). This dramatic difference between pedestrian fatalities during the night and […]
Visibility aids, such as lighting, reflectors, and fluorescent material, are marketed to vulnerable road users (VRUs) like pedestrians and bicyclists as a way to enhance their safety on the road. These visibility aids increase the VRU’s contrast within the roadway environment therefore increasing their visibility. However, increasing visibility does not necessarily mean enhancing conspicuity. For […]
There are various visibility aids marketed for vulnerable road users (VRUs). Here, the term VRU is used to describe unprotected road users such as pedestrians and bicyclists. Visibility aids are designed to increase a VRU’s contrast within their environment, making them more distinguishable from the background to a driver. These visibility aids can include both […]
If there is a human involved in the case, there is a good chance that human factors theories and principles will be applicable. Human factors is the study of people interacting with their surrounding environment. A human factors expert applies their knowledge of human capabilities and limitations to each unique case to assess the physical, […]
