| dc.description.abstract | While trains are convenient for travel and for transporting goods, they have become a riskier
mode of transport over recent years. At present time, a large number of accidents have occurred
due to railway mishaps in Bangladesh. Mismanaged railway crossings and faulty rail lines are the
principle reasons behind the accidents. Moreover, Bangladesh Railway has attributed a huge
sector of those losses to massive manpower and maintenance expenses it engulfs. Both the
problems can be resolved by an intelligent unmanned railway introduced in this paper, which will
not only reduce the risk of human lives but also a huge amount of public property. The total
system is an integration of a few stand-alone sub-systems powered by micro-controllers which
perform simultaneously by synchronizing the data to improve the safety and efficiency of the
railway transport in different sectors. A part of the system is a completely unmanned crossing
system, which ensures the safe crossing of a train in the busy city areas. Sensing the flaws in the
railway tracks is also included in this system. This research depends on microcontroller based
subsystems to reduce the complexity, uncertainty and cost. Then the controller unit determines
whether the obstacle is train or stuck and takes necessary steps by controlling the gate, alarm
generator and signal lights. Experimental studies show that the proposed methodology
provides a more cost effective, reliable and simpler railway gate controller than existing
dominant work. | en_US |
