Smart Railway Crossing System is a great integration of IoT technologies. This will enhance and can ensure the safety of road and rail-way users. The Internet of Things (IoT) is a rapidly growing network of interconnected devices that can collect and exchange data without human intervention. In Smart Railway Crossing System (SRCS) the integration of IoT technologies will enable SRCS to become more efficient and intelligent, allowing them to respond to real-time data and improve traffic flow. IoT sensors placed at railway crossings can detect approaching trains and communicate with nearby vehicles to alert drivers to stop or slow down. The collected data from the sensors used to run the smart rail crossing system properly and helpful for the traffic system near the rail crossing area. However, it is important to ensure that these systems are designed with security and privacy in mind to prevent unauthorized access and misuse of collected data.
