Internet of Things (IoT)-based apparatus and method for rail crossing alerting of static or dynamic railtrack intrusions


There are over one hundred and fifty thousand at-level railroad crossing in the Unites States. Unfortunately about 2,000 accidents a year occur in the U.S., with approximately 200 death a year (and a higher number of injuries), due to cars, trucks, and people finding themselves, for various reasons, on the tracks of an incoming train while positioned within the barriers (working or non-working) of a road-rail crossing. The apparatus discussed in this paper, and the subtending methods, provides a relatively inexpensive Internet of Things (IoT)-oriented system that can be used to either alert a rail operator that there is an obstruction on the tracks or even interwork with a Positive Train Control (PTC) system to attempt to automatically stop an incoming train.
