Curbing vehicular urban pollution in China: Investigating the usage intentionof public electric buses

Public electric bus (PEB) usage remains critical in reducing carbon emissions, traffic congestion, energy consumption, resource exhaustion, and environmental pollution. PEB usage revolves around consumer acceptance, and assessing the psychological factors accounting for using PEBs is essential in mitigating these challenges for a sustainable environment. The study extends the reasoned action theory (TRA) with environmental awareness, convenience, and personal norms in investigating residents' intention to use electric buses in Nanjing, China. 405 responses were gathered through an online survey and evaluated using Structural Equation Modeling (SEM). Statistical analysis showed that the structural model (66.4%) explained public electric bus use better than the original TRA model (20.7%). Attitude, subjective norms, personal norms, environmental awareness, and convenience directly influenced the intention to use PEBs. Personal norms related to attitude positively. Environmental awareness related to personal norms in PEB use. Subjective norms partially mediated the impact of personal norms on the intention to use PEBs. Convenience moderated the interaction between personal norms and intention to use PEBs. Respondents differed in income level, educational level, and employment but not gender in their inclinations to use PEBs. The current study recommends potent policy implications to enhance and ensure the maximum use of PEBs.
