The purpose of this paper is to assess the management systems and establish the extent to which they are effective in enhancing the performance of the road passenger transport companies in Rwanda. Three hundred thirty four (334) respondents were randomly and purposively selected from three transport companies. The data was analyzed using SPSS and MS Excel for windows statistical software and frequencies, pie charts, frequency tables and chi square (X2) tests of relationships were conducted to determine the pattern among the study variables. The results showed a statistically significant relationship in the vehicle management systems among the three road transport companies (p=0.000<0.05). Findings of both private and public companies indicated that all were moderately effective using scientific accepted formats. Finally, the research recommends that the government owned ONATRACOM Company should put more effort in cost management because the findings revealed that cost management is given less attention by the management. Private transport companies should consider implementing briefing, pre-journey and en-route information as some of the important passenger management systems.
