摘要

NHTSA has sponsored several studies in the past which have been directed to observe and record belt usage by drivers in cars equipped with different warning and hardware systems in 19 cities. The purpose of the current research effort is to continue observing and recording belt usage for a period of 26 months (November 1977-December 1979) in these same 19 cities to determine the effectiveness of various older, as well as newer, safety belt systems in increasing belt usage. Specific objectives of this study are: To continue to monitor safety belt usage rates by drivers in all model year cars (Model years 1964 through 1980); Analyze usage data by: Type of belt system, Age and sex of driver, Model year of car, Region of country, Type of road, Month of year, Car make and model. In addition to observing and recording safety belt usage at primary road intersections and freeway exit sites in the 19 cities, the study was designed to observe safety belt usage: (1) in rural areas; and (2) on three major turnpikes -- Massachusetts, Pennsylvania and Florida for a period of 12 months. The primary purpose of the Turnpike Study was to measure daytime vs. nighttime safety belt usage among drivers.
