手机分心对行人过街中信息加工及行为的影响

he proportion of pedestrian casualties involving mobile phones during road crossing keeps increasing. The distraction from mobile phone affects both pedestrian information processing and behavior. Compared with non-distracted pedestrians, pedestrians using a cellphone have a narrower scope of attention (esp. in the peripheral visual field), making it more difficult to perceive visual and auditory cues in traffic scenes. They are also more likely to miss street crossing opportunities or make risky decisions. As for the motor control ability, using cell phone also led to altered gait patterns and declined action stability. Although these impairments are modulated by specific task types (e.g. conversing vs. browsing), the distraction of mobile phones generally increases the risk for pedestrians crossing the street. To integrate these findings, a conceptual model was proposed on the effect of mobile phone distraction on pedestrians information processing and behavior. Based on the model, future research needs to evaluate how mobile phone distraction affects pedestrian auditory information perception, and its impacts on sub processes within the gap acceptance decision-making to develop targeted interventions.
