Abstract: This study seeks to identify challenges faced by public transportation in Southern African Development Community (SADC). Quantitative data was gathered using a close-ended questionnaire from 100 responses comprised of bus drivers and passengers on the Johannesburg-Harare route. The sample size used for the study complied with the method of data analysis. Descriptive, mean item score, non-parametric test and principal component analysis were used to analyse the data. To ensure the reliability of the survey, Cronbach's alpha coefficient was conducted, and a value of 0.944 was obtained. The findings revealed that modal shift, inadequate planning, driver performance, security, external costs and on-travel-related factors are the significant challenges transport companies face in the quest to assure satisfaction. The study makes recommendations to aid in abating the identified challenges for better economic fostering and effective regional integration in southern Africa.
