Abstract
In recent years, Railway level crossing (RLC) accidents is one of the major contributing factors
of railway related fatality problems in many countries. A fundamental requirement in pedestrians
safety planning is the isolation of level crossings along the railway. This is normally assisted by
precautions which are used to give information for every group of pedestrians. The study was
done by direct observation and Census (random sampling technique by taking 15 minutes
duration) to examine the flow of pedestrians and trains along the level crossings (Stations) of the
newly build East-West line of Addis Ababa Light Rail Transit.
From the collected data; by calculating the train pedestrian value and pedestrian category, the
necessity of precautions (road markings, audible warnings, pedestrian signals, tactile threshold
and guard rails) is analyzed. And also by taking the flow of pedestrians from the graph, the
necessity of grade separation is analyzed.
The result of the reasearch is that; Road markings, audible warnings and pedestrian signals are
necessary in all stations. Since the necessity of tactile threshold is dependent on the alignment of
crossings and adjacent footways, 8 out of 14 stations are isolated to construct a tactile threshold.
And also the location of all railway stations is at the middle of vehicle road. So, it is unable to
construct a guard rail in every station.
In some areas, there is a crowded flow of pedestrians and due to that reason pedestrians are
trying to use vehicle crossings as a crossing. It may create a collision between pedestrians and
road vehicles due to the congestion. This study recommends the necessity of grade separations
(Bridges or Tunnels) in order to avoid those accidents.
