    Abstract: The railways being the lifeline of transportation and the most preferential mode of transportation, tends to move through the thickly inhabited areas more often than not. This, however, leads to a situation where railway tracks traverse the roadways which is yet, another important genre of transportation. The point of juncture of railway-track and the roadway is acknowledged as level-crossing. One important concern of transportation experts is to exercise robust safety at the level crossings. The researchers intend to make use of the developments in the communication system and the internet of things to devise an early warning system for unmanned crossings. Objective of current work is to deliver an audio-visual caution to commuters about an upcoming vehicle (train). The need for such systems and its design implementation along with feasibility is discussed herein.
