12011. Pedestrian Level Crossing Safety On The East West Line Of Addis Ababa Light Rail Transit

In recent years, Railway level crossing (RLC) accidents is one of the major contributing factorsrnof railway related fatality problems in many countries. A fundamental requirement in pedestriansrnsafety planning is the isolation of level crossings along the railway. This is normally assisted...

12012. Suspension Damping Influence On Ride Comfort Of Passenger Rail Vehicle

This paper analyzes the secondary suspension damping influence of a passenger rail vehiclernupon the ride comfort, evaluated via the sterling ride comfort index. The selection of dampingrnratio is a sensitive issue when a too small damping may compromise the vehicle dynamicrnperformance, and a too...

12013. Evaluation Of Alternative Track Alignments On Whole Life Cost Of Lot 11 Section Of The Awash-weldiya Railway Line

Geometric design is an essential and major component in the design development of railway projects. Geometric alignments (horizontal and vertical) affect project cost and safety significantly keeping other factors constant. The effect of track alignment on cost of awash-weldiya railway project in...

12014. Development Of Material For The Overhead Contact Line Of The Addis Ababa Light Rail Transit (aa-lrt)

The purpose of this research is to develop a better material for the AA-LRT overhead contact line production. So with this in mind, the mechanical wear and corrosion resistance as well as the conductivity and hardness test of Cu-Ag and three other age-hardened copper alloys (Cu-Sn, Cu-Sn-Cr, and...
