POWS EVALUATION SURVEY.
Abstract
A Pyrotechnic Outside Warning System (POWS), consisting of rocket propelled vehicle, sound package, flare, smoke cloud and parachute, was evaluated as an alerting means for remote areas. The evaluation program consisted of three phases. In the procurement/technical evaluation phase tests were conducted with the individual alerting mechanisms, their sequencing and the payload vehicle. The survey phase involved all the necessary tasks for measuring the systems effectiveness as an administered by face-to-face interviews. In the analysis phase, a computer program was designed to provide the desired device/mechanism effectiveness of POWS as a function of distance from the test site. The results of HRB-Singer's evaluation show that the basic concept of supplementary outside warning through the use of an acoustical signal for gaining popular attention and a visual signal for identification is valid. POWS with its combined sonic and visual indicators could function with a reasonably high degree of reliability for ranges of two and onehalf miles in rural environments and two miles in suburban environments.
