LIDAR-Based Security Systems for Rail Transit 

  • Integrated Railway Track Security Hardware & Software Systems
  • TIDS for Platform Fall Detection and Intrusion Detection
  • SIDS for Transit Infrastructure, Right-of-Way, and Tunnel Security      
Today's biggest and most expensive weakness for transit electronic safety and security system operators is false alarms.


False alarms are a hassle and expensive to manage. They lead to alarm fatigue, a heightened risk of security breaches, and affect safety operations. Addressing these deficiencies requires modernizing the underlying detection systems and an appropriate automatic or manual control response so that these railway track and infrastructure security systems can accurately and proactively detect real threats.

LIDAR Safety & Security Solution

LIDAR-based railway track security systems are deployed at transit stations and inside train tunnels to enhance passenger safety and provide infrastructure security. The systems are designed to  automatically transmit the necessary information to:  


  • The automatic train safety control systems

  • The train drivers for visual confirmation and response

  • Rail control center for overall supervision and response co-ordination.


The TIDS and SIDS systems have been developed exclusively for rail transit solutions that combine current 3D digital LIDAR technology with the operational requirements gained from over 400 transit installations of 2D LIDAR technology at rail transit stations and tunnels across North America.

TIDS - Rail Station Platform Fall Detection

Advanced Object Detection System 

Designed to enhance the safety of passengers at rail stations, by detecting and automatically sending alerts when a person or dangerous object enters the station track area. 


SIDS – End of Platform and Tunnel Intrusion Detection 

Restricted Zone Detection System 

LIDAR-based railway track monitoring system designed to detect and send automatic alerts when a person enters a track restricted zone, such as station end-of-platform, tunnels and right-of-ways.
