The train collision avoidance system (TCAS) offers a warning or situational awareness that is specifically designed to prevent train collisions. Such systems are also extensively used in the mining and automotive sectors, apart from the railways sector, to avoid accidents caused by collisions. These are not specific to train mounting and can be deployed on railway tracks, crossings, and track-changing junctions.

Smart airports are modern aviation facilities that incorporate advanced technologies and innovative solutions to enhance the overall passenger experience, optimize operations, and improve safety and security. These airports leverage digital, data-driven, and interconnected systems to create a more efficient, convenient, and sustainable travel environment.

SUAVs are small aircraft that are flown remotely and without direct human interaction and used for monitoring, aerial photography, product-deliveries, agriculture, policing and surveillance, infrastructure inspections, and others. In the event of accidents or natural disasters, receiving information from the air has become more important. SUAVs are getting a lot of interest as a reliable and effective way to gather such information.
