Considering Spatial Heterogeneity and Time of Day in Self-Reported Seat Belt Use

Despite the well-known impact of seat belt use in injury prevention, vehicle occupants often fail to wear seat belts. Previous self-reported studies have often not separated the analysis of seat belt use between daytime and nighttime and the role of spatial heterogeneity have often been neglected in the study designs. The aim of this study is to investigate the association between education, engineering, enforcement (the three E’s) and demographic variables with self-reported seat belt use for daytime and nighttime by considering the issue of spatial heterogeneity. The study consists of a self-reported seat belt use survey conducted in a sample of 814 respondents aged 18-50 in six East Tennessee counties. Average self-reported seat belt use rate for both daytime and nighttime was 89% that is slightly lower than roadside observations in the study area. Comparison of a global binary logit model with geographically weighted regression logit model (i.e., local model) indicates that the existence of coefficient variation over the space is not substantial in both the daytime and nighttime models. Multivariate results indicate that perception of receiving a ticket for not wearing a seat belt, uncomfortable seat belt design, and forgetting to put on the seat belt, driving for a short distance, and driving exposure have a significant negative association with self-reported seat belt use. Results also indicate that imposing negative points on driver license is an effective method for increasing seat belt use rate. Findings are discussed in line with road traffic safety countermeasures.
