Transportation plays an important role in serving economic, social, political, and population mobility. Public transport is gaining importance for providing sustainability, such as by reducing traffic congestion, noise levels, providing better air quality, and contributing to public health. Public transportation facilities are undeveloped in Northern Cyprus, and only buses and minibuses are available. Many people are ready to shift to public transportation if safe, reliable, and affordable transportation options are available. The theory of planned behaviour was used, and an online survey including 33 questions was conducted with the contributions of 385 participants. All variables of the theory of planned behaviour have a greater than 0.70 Cronbach’s alpha value; therefore, multiple linear regression analysis with the SPSS V27 program was conducted to detect the impact of attitude, subjective norms, and perceived behavioural control on behavioural intention. Note that 32.2% of intention is indicated by attitude, subjective norms, and perceived behavioural control. The study concluded that subjective norms and perceived behavioural control have a positive influence on behavioural intention. Attitude is not a predictor of behavioural intention. Subjective norms are the strongest (β = 0.438, p < 0.001), and perceived behavioural control is the weakest (β = 0.438, p < 0.001) predictor of public transport usage intention.
