Customer challenges
1
The platform–train interface is a top safety risk; operators need faster automatic confirmation of track-clear and intrusion, and berthing or platform-screen-door issues can delay or endanger service.
Customer benefits
Faster, safer dispatch; earlier intrusion and emergency-stop support; fewer PSD incidents and delays; a vision safety layer that augments existing signaling.
