Subjective workload and performance of young drivers faced to unexpected pedestrian crossings

The aim of the present study is to identify which of subjective workload dimensions are influenced by driving experience and situation complexity, and which ones influence driving performance. Method: Fifty-seven young drivers [15 traditionally trained novices, 12 early-trained novices, 15 with three years of experience and 15 with at least five years of experience] were randomly assigned to three situations [simple, moderately complex and very complex] in a driving simulator. Self-reported levels of workload during unexpected pedestrian crossings were collected by a questionnaire [NASA-TLX] between each situation. Results and discussion: Three workload subscales decreased with experience and increased with situation complexity, and one subscale was correlated to driving performance
