Abstract: The proportion of pedestrian casualties involving mobile phones use while crossing road keep increasing. This paper reviewed recent studies on how mobile phone distraction affected pedestrian information processing and behavior process. Compared with non-distracted pedestrians, using a cellphone leads to a narrower scope of attention (esp. 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. Therefore, the distraction of mobile phones increases the risk of pedestrians crossing the street and is more likely to cause crossing accidents. To integrate these findings, this paper proposed a conceptual model of the effect of mobile phone distraction on pedestrians ’information processing and behavior. Based on the model, we highlighted research needs on how mobile phone distraction affects pedestrian auditory information perception, and its impacts on sub processes within gap acceptance decision making as to develop targeted interventions.
