Platform Track Intrusion Detection System Evaluation for Los Angeles County Metropolitan Transportation Authority

This project evaluates the capabilities of the Platform Track Intrusion Detection System (PTIDS) at/near passenger platforms to detect bodies/ obstacles intruding into the right-of-way and provide immediate warning to rail operations safety systems and personnel. This system monitors the track area in front of the platform through a row of transmitter and receiver sensor module pairs on each side of the track. The plane between the transmitter and receiver modules is set to a reasonable height below the platform and above the top and rail. An object is detected by the Station Track Intrusion Detection (STID) function when it falls through this plane and interrupts the radar signal between the transmission modules and corresponding receiver modules. Software algorithms are then used to filter unwanted detections, including the train.
