| Abstract |
A variety of high technology in-cab devices have been proposed for use in heavy trucks. Many of these devices introduce subsidiary tasks which may compete with the drivers primary task of safely controlling the vehicle at all times. As part of this research project into heavy vehicle driver workloads, the Battelle team developed a workload assessment protocol suitable to assess the safety implications of high technology systems that might be introduced into heavy trucks. Task 1 of this project involved review of existing task analysis data and protocols (Tijerina, et al., 1991). Task 2 involved the fdefining a standard heavy vehicle configuration and a set of standard driving tasks to serve as a baseline condition for measuring workload in future phases of the project. This report presents the identification of a standard heavy vehicle configuration and driver tasks that would serve as baseline conditions for measuring workload. A subject matter expert and review of Department of Transportation manuals determined that a standard configuration would have the following functional characteristics: combination tractor and single trailer vehicle; conventional cab configuration with sleeper box optional; flat panel dashboard; diesel power with air brakes; and an absence of high-technology devices. Standard driving tasks reviewed in Task 1 and those results were categorized, rewritten for application, and screened by a subject matter expert, thus identifying key driving tasks. A list of basic driver behaviors (sub-tasks) is presented to complement the key driving tasks. References, 5 tables, 20 p. |
