No fruitful steps have been taken so far in these areas. our paper deals with automatic railway gate operation (i.e.‚) automatic railway gate at a level crossing replacing the gates operated by the gatekeepers‚ It deals with two things‚ Firstly it deals with the reduction of time for which the gate is being kept closed and secondly‚ to provide safety to the road users by reducing the accidents. By employing the automatic railway gate control at the level crossing the arrival of the train is detected

Throughout most of history‚ the amount of waste generated by humans was insignificant due to low population density and low societal levels of the exploitation of natural resources. Common waste produced during pre-modern times was mainly ashes and human biodegradable waste‚ and these were released back into the ground locally‚ with minimum environmental impact. Tools made out of wood or metal were generally reused or passed down through the generations. However‚ some civilizations do seem to
