Abstract:

It causes a significant hazard to traffic safety the car drivers have been looking in the direction where the other road users were but have not perceived the presence of the other parties, which is called ‘looked-but-failed-to-see’ (LBFTS) error. This paper first analyzes the main factors which contribute to LBFTS from the perspective of both bottom-up and top-down mechanisms. That Computational Framework is not able to fully explained circumstances because of its insufficient consideration of driver’s practical experience, expectancy and attentional set. Therefore, the extended model of Computational Framework is proposed to offer comprehensive explanations to the LBFTS using bottom-up and top-down mechanisms.

Key words: sensory conspicuity, mental workload, attentional set, driver schemata, inattentional blindness
