Digital train signage

Share

In 2018 we took on the Digital Signage project for the Path trains. Our software parses the entirely custom binary format provided by the reporting systems and sends updates to the signage within 100 milliseconds. As a piece of public facing infrastructure we followed a disaster recovery protocol where over half of the machines in our system can go down and the system remains fully functional.

Our signage features included:

  • Multiple easy to configure layouts for different sized displays
  • Interfaces to change scrollings text, and to override an entire sign
  • A user management system with a full audit trail to allow any operator manage the signs
  • Lightweight APIs which feed data to both the signage and mobile applications

This project was delivered in a strict 4 month timeline. Since launching the product we can proudly say there have been ZERO bugs.
