Effects of mobile phone use on driving performance in a multiresource workload scenario

Objective: This study explores the influence of mobile phone secondary tasks on driving from the perspective of visual, auditory, cognitive, and psychomotor (VACP) multiple resource theory, and it is anticipated to benefit the human-centered design of mobile phone use while driving.

Methods: The present study investigated 6 typical phone use scenarios while driving and analyzed the effects of phone use distractions on driving performance. Thirty-six participants were recruited to participate in this experiment. We abandoned traditional secondary tasks such as conversations or dialing, in which cognitive resources can become interference. Instead, we adopted an arrow secondary task and an n-back delayed digit recall task.

Results: The results show that all mobile phone use scenarios have a significant influence on driving performance, especially on lateral vehicle control. The visual plus psychomotor resource occupation scenario demonstrated the greatest deterioration of driving performance, and there was a significant deterioration of driving speed and steering wheel angle once the psychomotor resource was occupied.

Conclusions: Phone use distraction leads to visual, cognitive, and/or motor resource functional limitations and thus causes lane violations and traffic accidents.

福州西湖水体富营养化现象分析 Ⅳ、底栖生态与底泥淤积

底泥黑臭，向水面冒气泡是福州西湖水体富营养化现象的一个突出表现。目前，有关管理部门主要靠定期挖泥清淤来控制底泥富营养状况。然而１９９９年秋季福州西湖底栖动物种类和数量调查结果却显示，由于底栖动物贫乏，西湖底泥富营养化问题将由于生态失调而进一步深化。建议将控制入湖泥沙量、减少挖泥频度、恢复底栖生态作为一项治淤措施予以考虑。
