The impacts of personality traits on the acceptance of shared e-scooters: Evidence from Tehran

Despite the growing research in traffic psychology and behavior, limited attention has been given to the impacts of public personality traits on the acceptance of emerging transportation technologies in the context of micromobility. In this study, we investigate the impact of personality traits on the adoption of shared dockless escooters (SDES). We extend the Technology Acceptance Model by incorporating trust, subjective norms, and personality traits. Using Partial Least Squares Structural Equation Modeling, we analyze 641 online questionnaire responses to test sixteen hypotheses. The findings show that trust and social influence have the most significant effects on the adoption of SDES, followed by perceived usefulness and perceived ease of use. Among the personality traits, sensation seeking directly influences behavioral intention. Openness to new experiences has a positive effect on the intention, while neuroticism has a negative effect. Based on these findings, several practical policies are suggested. To promote SDES, policymakers should leverage social media engaging those high in openness to new experiences. Safety measures may appeal to individuals high in neuroticism, while loyalty programs may incentivize sensation-seekers. Investing in dedicated pathways and supportive regulations can contribute to SDES reliability and encourage users to consider SDES as a convenient option for short-to-medium range trips.
