| Abstract | This report covers the seventh in a series of tasks involving the assessment of driver workload in heavy vehicle operation associated with in-cab devices or systems. This report addresses the application of a workload assessment protocol and measurement system to empirically assess the degree to which a text message and cellular phone system impose workload on heavy vehicle drivers. Sixteen professional drivers performed over-the-road driving under various conditions of lighting (dark vs. light), road type (divided vs. undivided), and traffic density (high vs. low). Drivers were asked to read a variety of CRT text messages, to perform several manual tasks, and to respond to several questions imposing cognitive demand. Results revealed that CRT text message impacts visual allocation and lanekeeping and that steering measures were also sensitive to the workload imposed by the CRT messages. Seven- and 10-digit dialing were the manual tasks associated with the highest demand for visual attention, but these tasks did not affect lanekeeping or speed measures. Cellular phone dialogues (cognitive tasks) impacted mirror sampling relative to open road driving. Recommendations for the implementation of the CRT text message system and the cellular phone system in-cab are discussed. |
