Abstract: An evaluation of skills and abilities that could conflict with each other during multi-task performance of driving and mobile telephone usage was performed using Fleishman's taxonomy of human performance with data collected using the job assessment software system computer-based survey tool. A literature review of mobile phone use during driving and dual task performance was first conducted to assess current thinking about the topic. Taxonomic-based data were collected from 27 survey respondents for the tasks of driving on city streets, driving on long distance highways, dialing a mobile telephone, and talking on a mobile telephone. Data were analyzed, and each of the driving tasks was compared against each mobile phone task using a compatibility index based around the taxonomy. Conclusions are reached that generally suggest some of the reasons, from a human factors viewpoint, why overall performance can be reduced during simultaneous driving and use of a mobile telephone.
