HAZARD MITIGATION FOR RAILWAY TRACK INTRUSIONS AT TRAIN STATION PLATFORMS
First Claim
1. A system for hazard mitigation related to an object intruding into a track zone at a train station platform, comprising:
- a structure including a fixed foundation and a surface layer cushionably placed above said foundation, wherein said structure is located in the track zone;
at least one sensor mounted between said surface layer and said foundation, wherein said sensor senses the weight of the object upon said surface layer and provides a sensor signal representative of said weight; and
a control unit to receive said sensor signal, to process said sensor signal to determine whether the object represents a potential hazard, and, if so to generate a warning signal.

Abstract
A hazard mitigation system to detect intrusion by an object into a track zone at a train station platform. A structure is provided that includes a fixed foundation and a surface layer that is cushionably placed above the foundation, such that the structure is located in the track zone. At least one sensor is mounted between the surface layer and the foundation. This sensor senses the weight of the object upon the surface layer and provides a sensor signal representative of that weight. A control unit receives the sensor signal, processes it to determine whether the object represents a potential hazard, and, if so generates a warning signal. The sensor can particularly include a strain or pressure gage, or a fiber optic sensor. When a fiber optic sensor is employed, it can particularly include a fiber Bragg grating.
