Light Rail Transit / Street Grade Crossing Safety System

SIL4 Systems, Incorporated performed Transit Innovations Deserving Exploratory Analysis (IDEA) project 68 to develop and test an intelligent Light Rail Transit/Street Grade Safety System that can be used by Light Rail Transit Systems. The concept investigated and developed in this project is active, adaptive, alert, and improves recording of crossing incidents for the approaching Light Rail Vehicle (LRV), its operator and the pedestrian, motorist, and/or worker at the crossing. The system has features including an active system which alerts the operator, as well as trespassers/workers, resulting in improved alertness/response time of the operators and persons at risk. Its active system also applies brakes. The system only works when a train approaches, thus avoiding false triggers. It includes a comprehensive record, which records events on the train and in the crossing. Because it is adaptable/portable, it can be set up in temporary work areas. Many of the features are implemented and achieved by the system such that it can activate the crossing light/alarm from the vehicle given the preset "time to crossing" programmed to 20 seconds. At this point, the Highway-Rail Crossing (HRC) package can then communicate to surface traffic controllers or gate mechanisms, or additional surface traffic lights/alarms via WiFi or Cellular networks; or relay logic interface. A comprehensive record is achieved via the on-board Data Logger/Event Recorder along with a Network Video Recorder record. The fact that the HRC package is compact, low profile and under 10 lbs means it can easily be mounted on a battery/work area lighting cart for temporary work area applications. Since it has an Onboard Global Positioning System, it can report its location wherever it is set-up.
