Ensuring Rail Safety: KAVACH, a Train Collision Avoidance System (TCAS)

KAVACH is a train collision avoidance system (TCAS) for preventing signal passing at danger (SPAD). SPAD is a pivotal safety mechanism designed to prevent railway accidents by ensuring trains do not pass signals at danger, adhere to speed limits, and avoid collisions. In this session, delve into a technical issue central to the SPAD system: the challenge of accurately detecting and responding to potential SPAD events under varying conditions. Explore how simulation environments, particularly those created with RoadRunner and RoadRunner Scenario, are crucial for modeling complex railway scenarios to test the SPAD system's efficacy. Participants will gain insights into:-    The architecture of the SPAD system, focusing on components such as junction boxes, signals, and loco pilot control systems. -    How to utilize RoadRunner for creating realistic railway models and scenarios. -    How to implement the SPAD system in Simulink^® for rigorous testing and validation. -    The application of automatic braking interventions and the system's alert mechanisms. You’ll discover specific topics including the integration of the SPAD system with simulation software, the development of test scenarios in Simulink, and the analysis of system responses to simulated SPAD events. You’ll also learn about the technologies and algorithms that underpin the SPAD system, including the use of Simulink for system modeling and testing. The aim of this project is to enhance railway safety by refining the SPAD system's ability to prevent accidents. This objective is deeply embedded in Tata Elxsi's commitment to leveraging advanced technologies and simulation tools for improving railway security. MATLAB and Simulink products have been instrumental in achieving this goal, providing a robust platform for system development, testing, and validation.
