PDI LUNCH TIME WEBINAR – ARCCA will present “Accident Reconstruction After Hours”

In 2018, the National Highway Traffic and Safety Administration (NHTSA) reported that 76% of pedestrian fatalities occurred during the dark lighting conditions.  A decrease in 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 oint 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,m 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.
