Passenger Management Systems – On-Board Unit (PMS-OBU)
We recently wrapped up a PMS-OBU (Passenger Management System – On-Board Unit) service demo, aimed at strengthening safety and security during automated vehicle operations. The day was all about putting CERTH detection systems to the test and collecting solid data to keep improving how the system performs in real-world conditions.
What was Tested
The demo brought together teams from TPG, CERTH, and UNIGE to explore how the PMS-OBU reacts to a variety of situations that can realistically occur in public transport. The goal was simple: observe, test, and record—so the system can learn and get better.
To make things realistic, we tested a wide range of scenarios, including:
- Fighting and screaming
- Vandalism and sounds of asset damage.
- Serious threat scenarios (knife attack) and distress signals.
- Bag snatching and shouting.
- Signs of intoxication.
- Falls and potential medical emergencies.
- Forgotten or unattended objects.
- Littering and cleanliness-related events scenarios repeatedly under identical conditions.
Not exactly a quiet commute, but a very useful one, with the team fully engaged in bringing the test scenarios to life.
What We Learned
The session generated a rich and diverse dataset across all scenarios. This information will feed directly into further improvements of the PMS-OBU detection algorithms, helping make the system more accurate and robust in day-to-day operations. It’s a concrete step toward safer and more reliable automated vehicle services.
More testing and fine-tuning will follow, as improving safety is an ongoing process rather than a one-off exercise. A big thank-you to the teams from TPG, CERTH, and UNIGE for their collaboration, creativity, and commitment throughout the day.
