Crash Risks by Commercial Motor Vehicle (CMV) Driver Schedules, Phase II

This study will collect additional data to answer important questions related to driver schedules and how these factors impact overall driver performance and fatigue. This study is being completed in phases. In Phase I, the research team collected HOS and crash data. In Phase II, the research team will use the data collected in Phase I to analyze crash risk as it relates to various aspects of the HOS provisions. This study will analyze: •Relative crash risk by hour of driving. •Relative crash risk by hour of driving per week. •Relative crash risk of driving breaks. •Relative crash risk as a function of recovery periods. •How each of the HOS provisions is being used. In addition, the study will design, develop, and deliver a database so that the data collected in this study can be used for future research efforts.
