Abstract:

The causal relationship between driving distraction and road crash is complex. The driver characteristics, roadway characters and constant changing driving environment will potentially affect the estimation. Even though we consider the same confounding factors, the conclusion will vary using different study design. In this study, we use a case-crossover design based on SHRP2 NDS data to investigate the causal relationship between driving distraction and crash risk. The rich information collected from SHRP2 NDS data allows more potential confounding factors to be matched for the case-crossover design. This study will focus on the evaluation of causal relationship between driving distraction and crash risk for case-crossover design. We will compare the difference between case-cohort design and case-crossover design in terms of the population of interest, analysis method and the advantages. Further, we will evaluate the efficiency of matching variable selection in case-crossover design and discuss the equivalent assumptions for the designs.
