RELATIONSHIP BETWEEN TRUCK RIDE QUALITY AND SAFETY OF OPERATIONS: METHODOLOGY DEVELOPMENT

This report presents an overall program plan, including sample experimental design, which can be used to determine the effects of vehicle vibration upon driver performance. The recommended solution is to combine a fixed-base driving simulator facility with a high-frequency motion base "ride quality" facility. The result is an interactive "rider simulator" that allows line drivers to perform real-world tasks while under very tightly controlled traffic and vibration scenarios. This approach has never been attempted before. Ride simulator facilities that meet the necessary requirements exist, and the driving simulator capability also exists at several research organizations throughout the U.S. The motion and driving task facilities could be brought together in about one year's time to the point of being ready to provide: an instrumented truck cab mounted on motion base and tied into a computer facility; various levels of cab acceleration data "measured" from variou trucks on both rough and smooth roads; and various driving scenarios. This simulator phase would require a minimum of 18 line driver subjects and should take about three months (including data analysis) to complete. When added to one year's preparation and three months for final report preparation, the overall program could be accomplished in about 18 months. The results of this study, if implemented by the NHTSA via subsequent procurement actions, would be used to determine if rulemaking standards for truck ride quality are warranted.
