Computer simulation of driver working memory processing
Kong F., Sui J.
In general, using simulations to solve problems of human behaviour, as is done in engineering, is particularly difficult. Making use of research into motor vehicle manoeuvrability, this article studies, from the engineering perspective, a computer simulation of working memory processing disabilities of automobile drivers. Firstly, utilizing theories drawn from cognitive psychology, motor vehicle manoeuvrability dynamics, and fuzzy control theory, a driver working memory simulation model is advanced. The model integrates working memory, which is a critical factor in predicting complex cognitive manipulation activities. Secondly, the driver's working memory processing is simulated using the model, and its effects on motor vehicle manoeuvrability and stability are assessed. The test result shows that there is an optimal range of processing time for driving. The lower limit of the range is limited by human physiological limits. The upper limit is defined by the task's complexity. The task could not be finished if the information processing time for finishing the complex task is greater than the upper limit. © IMechE 2005.
