Abstract
This research paper mainly deals with the train operation system development for railway
transport of Addis Ababa LRT. The prime justification for the introduction of a Light Rail
System in Addis Ababa is the provision of major improvements to public transport in the city,
particularly with reference to greatly increased carrying capacity, reduced pollution and
improved the service of operation. To achieve this, system analysis approach is presented for the
investigation of train operations in railway stations and routes based on demand, network,
timetable (train schedule), and rolling stock and crew analysis data. Network and train schedule
analysis are the main focus of this paper which are solved using a simulation model programmer
language Arena5. The simulation model is formulated in the way that it represents the
appropriate actual working system of the Addis Ababa LRT. For the constructed simulation
model, the “Program” is well made and run. The simulation model combines the two routes
together and the number of waiting time result shows the stations operations are busy from
Lideta to Meskel Square including the route between both stations where the two routes separate
to east and south lines. Therefore, these route and stations are the bottle neck of the Addis Ababa
LRT corridors. Testing the real operation by simulation, Delay minimization and resource
utilization, waiting time for each station and the route bottle neck identification are the major
output of the research. This research is done depending on the actual data for the Addis Ababa
light rail transit and its application is more for the future operation coming soon. Finally, the
operation data are verified and the simulation model output is valid.
