This final report has been prepared by the Advanced Vehicle Dynamics Lab (AVDL) at Virginia Tech for the Safety IDEA Program, as part of the completion requirements for the project entitled 'Safety Effects of Operator Seat Design in Large Commercial Vehicles'. This report and the work in this project have been reviewed by the Expert Review Panel (ERP) for this project. This report documents our project accomplishments and results, as specified in the IDEA Report Guidelines. The executive summary highlights key points that are explained in detail in this report. A series of road tests were performed using commercial truck drivers in the daily operations of a revenue service fleet. Drivers were asked a series of questions to assess subjective performance of the vehicle environment, and pressure distribution measurements were collected throughout each test session. This data was then analyzed to assess the validity of two newly proposed measures to evaluate subjective ratings of driver fatigue. The results highlight the advantages of using these measures to evaluate the fatigue performance of distinct types of seat cushions - namely foam and air-inflated seat cushions.
