Multimodal transport between sea, road and rail, has received a large interest in recent years. Hence, this research focusedon the determinants factors of multimodal transport effectiveness. And then how these factors affect multimodal effectiveness. Primary data were collected witha structured questionnaire and interview as a data collection instrument was usedandsupported by secondary data. Out of the 228 questionnaires distributed only 200 were successfully returned back. Descriptive and inferential statistics analysis method were used to analysis the outputs (i.e. mean, ANOVA, t-tests and regression) using SPSS Software. Five determinant factors of multimodal effectiveness (i.e. transitcost, transit time, logisticsinfrastructures, services reliability and cargo safety and liability) were analyzed. Based on the findings of the research most of the respondents were dissatisfied on fairness of transit cost, moderately agreed on the infrastructures, service reliability and transit time, and agree on the cargo safety and liability.Hence, based on the findings of the research it is possible to conclude that shortages of logistics infrastructures which result in increased transit cost and time.It also indicate that transit cost, transit time, logistics infrastructure and service reliabilityhave significant impact on multimodal effectiveness. In addition, least square regression showed that 65 percentage of the variability of multimodal effectiveness was explained by the independent variables. Lastly, the researcher recommends Ethiopian Shipping Logistics Service Enterprise, should improve information technology infrastructures and equipped all the ports and terminalslatest machineries and facilities in the future. Furthermore, remove double costs and should provide one stop services for the effectiveness of multimodal transport system.
