The Addis Ababa Light Rail Transit, East-West line in particular, has a number of at-grade rail-road crossings with an increasing road traffic volumes and train frequencies which affect the smooth operation of the Light Rail Vehicles.rnTherefore, a study on feasibility of at-grade versus highway overpass rail-road crossings was sought of, by considering the economic aspects involved with each; with the objective of determining which of the two crossings would be feasible for investment. Different techniques used to achieve the objectives included: manual traffic counts technique, document review, field observations, queuing model, and NPV, IRR, BCR analysis methods, sensitivity analysis technique, etc.rnBased on the methodology, different economic and transport impact cost and benefit values were obtained, with the highway overpass crossing generating a net benefit of $6,758,782.17, unlike the at-grade rail-road crossing that gave a net loss of -$7,753,428.07. The aggregated at-grade and highway overpass rail-road crossing cost values of $2,613,280 and $1,880,786, respectively; and benefit values of $307,866 and $763,011.38, respectively, were obtained.rnThe feasibility of highway overpass crossing over the at-grade rail-road crossing was determined based on the NPV, BCR, IRR analysis results. Where, $119,875.45 NPV, 15.87% IRR and 3.3704 BCR value for highway overpass crossing; and -$3,427,488.39 NPV, 0.2576 BCR and a negative IRR for at-grade rail-road crossing. These results show that the highway overpass crossing is feasible than the at-grade crossing.rnTherefore, this thesis is relevant in identification and quantification of the transport and economic impacts; supports decision-making when choosing a rail-road crossing alternative.
