| Analysis of the High Risk versus Low-Risk Commercial Motor Vehicle Driver |
| The research will be conducted in two phases. Phase I, Analysis of Existing Data, is expected to last one year and will leverage data from two different driving studies: SimVal II, and DDMS FOT. SimVal II is expected to collect data on novice commercial motor vehicle (CMV) drivers using instrumented trucks. The DDWS FOT collected data on 103 CMV drivers, each for approximately 12 weeks, as they made their normal delivery runs. The data from the FOT includes drivers with various levels of experience and risk levels. The highest risk and the lowest risk drivers will be characterized with regard to involvement in critical incidents. In addition, the driving behavior, performance, and outcome for both groups will be compared with each other, and with the data collected on the novice drivers in the SimVal II study. Data from these three groups will be analyzed to assess performance, behavior, and outcome discrepancies and similarities.
Phase II of the Naturalistic Driving Study with 1,000,000 Milers, is expected to last 2 years and will involve a new naturalistic data collection effort and subsequent analysis. This new on-road data collection will include some of the safest CMV drivers in the industry (million milers drivers who have driven 1 million crash-free miles). Naturalistic on-road data will be collected for approximately one year. This data will be analyzed to assess the behavior, performance, and outcome characteristics of these elite drivers. The analysis will follow the same method as that conducted in Phase I and a comparison will be made between the three original groups of drivers and the million milers. Depending on the data collected in the SimVal II study, Phase II may also include novice drivers.
