Abstract
Railway transport system hauls huge commodities and passengers from one location to another. Thereby, protection of the freight, passenger and the train itself from collisions and hazards is the pillar of railway system. There have been plenty of methods created to solve train protection problem all over the world so far. This thesis is also focused on solving protection problem in the route from Addis Ababa to Djibouti border (Dewele). Addis Ababa-Djibouti route has both single and double tracks, serves to both freight and passenger trains. Moving Trains at this track have different speeds, passenger trains are relatively run at high speed. Another problem within this track is head-on conflict of outward and inward running trains at the single track. This situation needs an effective train control and protection system in order to protect train collision, increase route capacity and supply proper power distribution. This thesis deals with designing proper, efficient and cost effective GSM-R radio coverage network for automatic train protection (ATP) system. Train detection mechanism is within GPS system. This work inspected the geographical and morphological nature of Addis Ababa-Djibouti (Dewele) route in detail. In this thesis the appropriate radio coverage is done depending on the real geographical nature of the route. The data rate load and dimension of each train, whole line and other communication services are calculated. This thesis has been using an appropriate path loss model to estimate the link budget of the network. The appropriate path loss model is selected with MATLAB software simulation. GSM-R radio network design parameters and appropriate algorithms are selected. Required mathematical calculations and analysis are defined on this thesis work. Then, lastly the network optimized with Atoll software.
