Metro lines featuring platform screen doors for protection against unauthorized passenger access require accurate management and correlation between the platform doors and the train side counterparts. The information exchange between onboard train controllers and the PSD controllers in each station are time-critical and safety-relevant to enable reliable door control and safe operation of the line.

A functional combination between passenger counters, traffic management system and door controllers can even be used to optimize and steer passenger flow.


Advantages:

• Correlation between train and platform doors
• Accurate door operation
• Improved door security
• Passenger flow management
• Advanced door information for passengers
