<p>This study utilized Extended Theory of Planned Behavior (ETPB) to understand the motivations behind pedestrians’ mobile phone usage while walking. A questionnaire comprising of 23 questions was designed based on ETPB to assess pedestrians’ mobile phone use characteristics and psychological factors. It comprised of demographic details, mobile phone usage characteristics, TPB constructs and perception on the effectiveness of the interventions to reduce mobile phone use while walking. The study employed an online survey and 430 samples were collected and analyzed. Structural equation modeling and ordinal logistic regression were used to explore and model the relation of socio-demographic variables, ETPB constructs, and mobile phone usage characteristics with frequency of mobile phone use while walking. The findings revealed that younger individuals and those with higher education levels were more likely to use mobile phones while walking. Positive attitudes towards phone usage, subjective norms, and facilitating circumstances significantly increased the likelihood of mobile phone use while walking, whereas high risk perception and distractions reduced this behavior. The presence of authority figures was observed to reduce mobile phone use while walking. Further, hands-free devices had a positive effect on frequency of phone use. The study provides valuable insights into the complex relationships between demographic variables, psychological constructs, and mobile phone usage behaviors among pedestrians. In the end, this study recommends conducting frequent public awareness campaigns for educating people detrimental effects of mobile phone use while walking.</p>
