Abstract

This article describes the methodology for the design of an observational safety belt use survey. It highlights the innovative features of the design: (a) the use of area probability sampling; (b) the measurement of the usage rate as the ratio of the estimated time front-seat passengers are belted in eligible vehicles to the total time in eligible vehicles; and (c) the implementation of procedures to reduce nonsampling or measurement error. Discussed are the development of the sampling plan, the sampling materials, the procedures used to conduct the observations, the approach for estimation and variance computation, and results from recent surveys.
