(57) In accordance with an embodiment of the invention, there is provided a system for
detecting a collision hazard at a predefined area along a railroad including, one
or more conductive loops, one or more train detectors, railway control interface and
a processing unit. The one or more inductive loops may be adapted to sense a presence
of a potentially hazardous object within the predefined area of the railroad and may
be adapted to provide information indicative of a progress of the potentially hazardous
object through the predefined area or a lack thereof. The one or more train detectors
may be adapted to indicate a train approaching the system. The railway control interface
may be adapted to receive railway control information that is indicative of an approach
by a train to the predefined area and/or that is indicative of a passage of a train
through the predefined area. The processing unit may be adapted to process data received
from the one or more inductive loops, from the one or more train detectors and from
the railway control interface. The processing unit may be adapted to switch from a
standby state to an alert state when it is determined that a potentially hazardous
object is substantially immobile while within the predefined area; and the processing
unit may be adapted to switch from the standby state or from the alert state to an
alarm state when it is determined that while a train is approaching the predefined
area or while a train is passing through the predefined area, there is a potentially
hazardous object within the predefined area.
