In 2018, the National Highway Traffic and Safety Administration (NHTSA) reported that 76% of pedestrian fatalities occurred during dark lighting conditions. A decrease in illumination often has a diminishing effect on the performance of the human visual system with a reduction in visual acuity. A driver’s ability to detect and recognize potential and immediate hazards is influenced by a number of factors, such as, illumination, luminance or contrast, size, pattern, eccentricity, and adaptation luminance. Accident reconstructionists are frequently asked to evaluate at what point in time an object or pedestrian would have been detectable or recognizable to an approaching driver.

This presentation will cover analysis techniques such as headlight and streetlight mapping, low-illumination photography, luminance measurements, and the application of small target visibility (STV) models to field data. Additionally, several case studies will be presented that demonstrate how these quantitative and scientific principles can be applied to incidents involving lighting and conspicuity issues.

Presented by
Dr. Daniel Wolfe, PH.D., ACTAR
Dr. Wolfe is a forensic scientist and accident reconstructionist specializing in the reconstruction of motor vehicle, pedestrian, and bicycle collisions. He specializes in collisions involving nighttime recognition and conspicuity issues, including headlight mapping of vehicles, illumination from roadway lighting, and nighttime photography.

Ian Grissom, BSME, ACTAR
Mr. Grissom is a forensic scientist and accident reconstructionist specializing in the investigation of motor vehicle accidents. He earned a Bachelor of Science in Mechanical Engineering at Seattle Pacific University and, during his studies, he focused on mechanical deformation and kinematics, including vehicle motion. Mr. Grissom is experienced in three dimensional laser scanning, photogrammetry, and processing data to perform analyses.

ARCCA specializes in figuring out what happened, or what could happen, over a wide range of situations and from the viewpoint of multiple technical disciplines. When clients have questions about a project, case, or claim and need an expert to analyze the facts and circumstances, ARCCA can help.
