Abstract
Delays in railway networks cause problems in the daily operation and result in reduced reliability
of the railway operation. Since the delay is not caused only by the overcrowded train schedules
but also the congestion at railway stations during the peak hours. In fact the determination of
train dwell time is an essential step in planning railway timetable with taking the passengers‘
experience into account.
In view of that, this research focuses on describing how it is possible to use passenger flow to
estimate the actual delays on Addis Ababa LRT. The combination of the passenger flow on dwell
time and the headway of a train is described, the research methodology adopt a strategy to
estimate these paramaters to consider various kinds of improvement and demonstrating the
possibility of predicting an eventual decreasing the delay of the trip and by the same time satisfy
the customers.
The result demonstrated that using together between dwell time and headway time to analyse the
reliability of AALRT have given a benefit return concerning about the delay caused but the
daily operation..
Finally, as the proposed investigated method is relatively easy to implement based on collection
passengers flow data, the contributions from the outcomes of these models are briefly addressed.
