A study was conducted on a closed track in both daytime and nighttime conditions to compare the conspicuity of three different types of safety garment for use by first responders; NFPA 1971 turnout gear coats, and ANSI/ISEA 107 and 207 safety vests. Eight participants, balanced for gender and age, drove instrumented vehicles on the closed track indicating the distance at which they could detect pedestrians in a simulated emergency response scene. Pedestrians, wearing one of the safety garments, stood adjacent to the emergency scene, on either the right or the left side, oriented either facing or perpendicular to oncoming traffic. The effect of pedestrian motion on detection was also examined by having pedestrians stationary or walking in place. |
