Abstract
Rail transport is an important mode of transport that can play significant role for economic
development of a country. Especially, Electric system train driving technology has many
advantages for environment protection and fuel consumption reduction.
Train control system is a broad section in railway technology and has responsible for ensuring
passenger’s safety and security during their journey. It also improves travel comfort, providing
real time multimedia information and access to social networks in stations or in motion. Accident
in railway technology is very series issue. So, maintaining safety is the first precondition for
railway transport.
To have safe operation in railway technology, train operators need to put in place an effective
and reliable train-to-ground and train to train communication technology. On the other hand, the
commercial wireless technologies have been evolving from voice centric 2G systems (e.g. GSM)
with limited data transmission capabilities to 4G broadband multiservice systems (LTE).
This Thesis addresses how the innovative commercial wireless technologies can enhance the
safety and reliability of AA-LRT. It introduces the implementation of long term evolution (LTE)
technology to Addis Ababa light railway. Each train communicates with their neighbor trains
through modern communication system called LTE. The information like train speed, train
distance and location of the train obtain from the speed capturing system and GPS technology.
This information processed through Microcontroller and the system alert for the train pilot even
it takes action on the braking system if necessary. The system decreases the need to construct
additional track in the city and reduce the probability of train collision.
In this scenario, this paper investigates capacity and quality of service improvement; energy
efficiency, mobility, passenger’s safety and security and results obtained from simulations are
presented.
