General Info

LiDAR and TOF Obstacle Detection

Piper’s SAFEGRADE system provides remote monitoring of grade crossings to detect occupancy and alert rail system operators to potential hazards. 

This integrated system is designed to capture the presence of vehicles, pedestrians, cyclists, and objects within the crossing quadrant with high resolution. The system interfaces with gates and signals to provide advanced warnings to approaching trains as well as triggering warning strobes and alarms in the area. SAFEGRADE is the smart solution for transit and freight rail operators seeking to protect their grade crossing and enhance public safety.

In the last 5 years, there have been more than 10,525 railroad crossing incidents resulting in 1,279 deaths.

SAFEGRADE Safety Solution

SAFEGRADE integrates Piper’s proprietary Time of Flight (TOF) cameras and Piper’s patented TrackSight™ LiDAR to continually scan grade crossings to detect obstacles and intrusions.

The high definition TOF cameras and LiDAR are installed at the corners of the grade crossing. Using a database image as reference, they can detect any changes to the fouling area in real-time – and reliably discern animate from inanimate objects. Piper’s public address system can play voice commands to intruders and the system is capable of storing all video and telematic data for training and forensic analysis.

According to the FRA, every four hours in the USA, a person or vehicle is struck by a train at a grade crossing.

A communications system is used for alerting operators to the presence of obstacles and for delivering the data to Rail Control Center (RCC) operators.

SAFEGRADE has multiple options for wayside-to-train communications for alerting approaching rolling stock including: LTE/5G, WiFi, 220MHZ, and UWB. Using a model of the track territory, Piper’s SAFEGRADE expands the distances for alerting to ensure safe stopping even at high speeds. The system is also expandable to integrate with train control operations to make calculations based on train speed and braking curves.  A systems administration control management platform monitors the health and safe operations of all components. SAFEGRADE can operate as a standalone solution or be integrated into other controlled systems.
