The VTTI Smart Outdoor Lighting Lab (SOLL) provides a unique combination of capabilities and test sites around the Virginia Tech campus that can be configured with adjustable lighting systems based on real-world conditions.
The VTTI SOLL provides a unique combination of capabilities and test sites around the Virginia Tech campus that can be configured with adjustable lighting systems based on real-world conditions. SOLL consists of the Virginia Smart Roads test sites focused on lighting and transportation safety as well as several parking lots and parking garages that are used to perform ongoing testing of lighting and control systems with Field Operational Testing projects. Current SOLL projects include an evaluation of the requirements for pedestrian lighting sponsored by the Federal Highway Administration along with two U.S. Department of Energy studies on the use of adaptive lighting in parking lots and the impacts of light on human health.
The Roadway Lighting Mobile Measurement System (RLMMS) was created by the Infrastructure-Based Safety Systems Lab at VTTI as a method for collecting in-situ roadway lighting performance data in addition to participant response data. Mounted on the roof of a vehicle (typically an SUV) a frame called the spider holds a series of sensors and a high accuracy GPS unit. The RLMMS can measure horizontal and vertical illuminance, luminance, color, and spectral output. These measurements are geocoded to allow for geospatial assessments of outdoor lighting. A small robot-based system is also available for assessing the lighting of paths and sidewalks.
