Addis Ababa Light Rail Transit implemented Light Rail Transit system as an integrated form of public transport, with the rail running through city centers and linking main commercial centers, presents interference with other modes of transportation (road transport) in Addis Ababa (Ethiopia).rnThe main objective of this thesis work is to develop a model of automated railway level crossing system which should manage road-railway transport on level crossing. It is developed by modelling of interfaced automatic railway gate system and automatic object detection system. Simulations are done by using LabView, proteus, Arduino tools and Configure Virtual Serial Port Driver I used for interfacing the two system.rnSimulation of the system demonstrated that automated level crossing system (interfaced railway automatic gate system and automatic object detection system) can detected an object at the position of x = 340.49, y = 251.24 with the score of 698.53 , 10 seconds for making decision for obstacle on crossing, which are good results according to AALRT level crossing background . Therefore, automated level crossing system be employed at AALRT level crossing where the chances of accidents should be avoided, the operation is automatic; error due to manual operation is prevented and it has reliable operation because time spend opening barrier manually is reduced.
