Intellectual Property India Publishes Patent Application for 'A Safety-Constrained Advisory System For Optimizing Train Movement And Section Throughput' Filed by Srm Institute Of Science And Technology, Ramapuram Campus; and Easwari Engineering College

MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641047825 A) filed by Srm Institute Of Science And Technology, Ramapuram Campus; and Easwari Engineering College, Chennai, Tamil Nadu, on April 15, for 'a safety-constrained advisory system for optimizing train movement and section throughput.'

Inventor(s) include S. Kanishka; Abay Nandhiga; Varsha V; Ankur Gohain; Varnika P; Thanvarshini VR; and Dr. M. B. Sudhan.

The application for the patent was published on May 1, under issue no. 18/2026.

According to the abstract released by the Intellectual Property India: "The present invention relates to a railway traffic optimization and advisory system configured to maximize section throughput while preserving controller authority. The system operates as a decision-support engine and does not directly control railway signaling infrastructure. The system comprises a data ingestion and digital twin simulation module, a rule-based safety constraint engine, a combinatorial optimization module utilizing constraint programming and mixed-integer linear programming, a disruption detection and re-planning module, a coordinated dual-end advisory dissemination mechanism, and a user interface module. The system computes optimal train meets, crossings, platform assignments, and precedence decisions under real-time operational constraints and generates consistent advisory instructions simultaneously for dispatching and receiving station authorities. Each advisory includes a recorded rationale for audit and traceability purposes. The system improves punctuality and section utilization with."
