Abstract: With the popularity of automobiles, traffic accidents frequently occur, and high mental workload during driving is an important cause of accidents. The multiple resources theory holds that the mental load is derived from the information processing process, and the information processing process can be described by four behavioral elements: visual, auditory, cognitive and psychomotor. Based on the multiple resources theory, this paper summarizes the analysis methods of typical driving tasks. On this basis, the load calculation process is programmed using the mental workload calculation model. In the paper, the task of "green light crossing straight" is selected for case analysis. The calculation system is used to realize the quantification transformation from "driving task" to "brain load". Finally, an experiment recording the operator's eye movement index and skin electricity level during the task is conducted, and the experimental results are compared with the result from the calculation system. The resulting load value comparison validates the correctness and availability of the system. Through the research of this paper, it is convenient to calculate and predict the mental workload of typical driving tasks to find the cause of high load, thus reducing the occurrence of traffic accidents.
