多任务处理能力差异对认知分心下跟车表现的影响

istracted driving has been one of the leading causes of the traffic accidents. In order to reveal the effects of distracted driving on car following behavior of drivers with different characteristics (multitasking ability), a driving simulation experiment was conducted. Two types of low-speed and high-speed urban road car following scenarios was constructed on the simulated driving system. The experiment collected driving performance indicators from 25 participants which were divided the participants into two groups according to their multitasking ability of the OSPAN task. Non-parametric tests were used to analyze the differences in driving performance of drivers with different OSPAN scores under the distraction task. The results indicate that: cognitive distraction will reduce the driver's lane offset, but there is a certain difference in the effect of distraction on drivers with different OSPAN scores at different speeds; generally speaking, drivers with better multitasking capabilities perform better with distractions; cognitive distractions may improve the driver's following performance in certain circumstances. Based on the above experimental results, some traffic management measures were proposed to reduce the impact of distracted driving on drivers.
