The Visibility Research Laboratory features a 140-foot-long dark tunnel, which is used to test materials for traffic signs and pavement markings. The facility also has capabilities to measure vehicle headlamps, sign lighting and roadway lighting.
TTI’s Visibility Research Laboratory is located in the TTI Headquarters building on The Texas A&M University System’s RELLIS Campus. The lab features a 140-foot-long by 15-foot-wide corridor for testing retroreflective materials as well as coatings, lights and other technologies designed to provide nighttime visibility. The lab also has ventilation systems to allow full-size vehicles to run in the lab while conducting human factors testing and evaluating installed headlamp illumination.
For the last 50 years, TTI researchers have conducted full-scale, closed-course night-time driving studies at the A&M System’s RELLIS Campus. This outdoor facility allows for static and dynamic visibility and human factors research at speeds of up to 70 mph. The Visibility Research Laboratory complements this full-scale testing facility.
