![]() The purpose is to verify that there is enough light present to identify tripping hazards. We measure the average amount of light on the horizontal plane at finished grade in foot candles. Illumination for Safety focuses on the horizontal plane, meaning the ground, as well as the color of the light. The illumination of these areas is intended to help pedestrians and bikers identify potential tripping hazards such as uneven pavement, tree roots, debris, and changes in elevation. The primary area of evaluation is typically the “street adjacent” pedestrian way or bike way, otherwise known as a sidewalk or path. It is intended for safe navigation of pedestrians while on foot, bike, or other normal means of non-motorized transportation. Illumination for Safety refers to the proper amount of illumination required for a person to detect a hazard and take appropriate action to mitigate that hazard. These may seem similar, but in reality they are very different. Lighting designers need to evaluate two important design objectives when designing pedestrian lighting, which we refer to as Illumination for Safety and Illumination for Security. ![]() Exterior lighting is critical to create a safe environment whether for a college campus, business park, urban environment, parking lot, public park, or anywhere else. ![]() In my last post, Pedestrian Lighting: A Case Study, I outlined a recent JDB Illumination commission to provide pedestrian lighting for a neighborhood adjacent to a college campus. ![]()
