Traffic Safety is the top priority in VIOHS' plans and programs. Along with the Virgin Islands Police Department (VIPD), VIOHS is actively engaged in several safety-related initiatives and this project involves conducting two annual Scientific Seat Belt Surveys for selected sites throughout the territory in cooperation with the VIPD. In the past, this survey followed the sampling design that adopts and adapts a method by Kish (1965) by which the primary sampling units in the Territory will be in clusters of 15 minutes in which the traffic going past a selected road site will be monitored.
