Abstract: Nowadays, road safety is that bad, however, it is common for college students to use mobile phones while walking. The Study 1 employed the theory of planned behavior (TPB) to explore the factors of pedestrian using a Smartphone while walking and effects of group counseling. On the basis of the first study 1, the Study 2 conducted group intervention in order to reduce the amount of pedestrians using mobile phone. The 59 college students were assigned to the experimental group (29 subjects) and the control group (30 subjects) who completed the selfdesigned TPB questionnaire and mobile phone addiction questionnaire before and after group counseling. This study showed: (1) behavioral attitude and subjective norms influence behavior indirectly through behavioral intention, while perceptual behavior controls direct and indirect prediction of behavior; (2) executive intention mediated the effects of behavioral intention on behavioral variables; (3) The behavior score of experimental group after intervention was lower than before intervention, but there was no significant difference in the control group. The theory of planned behavior provided a general theoretical framework for explaining the factors that influenced college students using mobile phones while walking, and group counseling had a positive effect on the reducing the incidence of using mobile phones while walking.
