The Effect of Cognitive Load on Driver's Recognition of Pedestrian Road-Crossing Intention
Objective Accurately recognizing pedestrian intentions is very important to ensure the safety of driv-ers and pedestrians,but drivers are likely to withstand varying degrees of cognitive load when operating the vehicles.The study aim to investigate the effect of cognitive load on the driver's recognition of pedestrian intentions.Methods The study manipulated the cognitive load bytheauditory N-backtask,askingparticipants(N =90)torecognizepe-destrian intentions in simulated driving scenarios.Results The drivers'discrimination of pedestrian intentions under the high load of two-back dual task is significantly lower than that of one-back dual task and single task,addition-ally there exists no difference between the latter two.Conclusion The increasing cognitive load weaken the discrimi-nation of identifying pedestrian intentions,suggesting that the involvement of cognitive resource is needed while recog-nizing pedestrian intentions.Accordingly,for the sake of improving driving safety,the drivers should keep their cogni-tive load as low as possible during driving.
