All aboard! 98%-accurate anonymous automated passenger counting on Swiss trains

 

A smart Parquery solution developed for the Swiss Federal Railways SBB CFF FFS

 

In collaboration with Switzerland's leading public transport provider, the Swiss Federal Railways (SBB CFF FFS), Parquery developed a camera-based onboard Automated Passenger Counter (APC). We adapted our versatile Artificial Intelligence (AI) framework to detect travelers with 98 % accuracy as they step on and off a train.

After evaluating multiple providers, we chose Parquery because they are excellent engineers and deliver accurate results.

As a team, we worked out the underlying conditions and requirements and ensured that everything was fully compliant with data protection. SBB were involved in the development process and Parquery's transparent, committed, and competent methodical approach made a strong impression on us.

Uses SBB’s existing infrastructure

 

Existing security cameras installed overhead monitor the two entrance areas of each train carriage. Additionally to their primary use, the cameras' footage is now employed to count passengers. Thus, no additional sensors, hardware, or cabling needed to be installed.

Besides their security use, the cameras' footage is used to count passengers

Difficulties overcome during the development

 

Low ceilings in train coaches and doors on either side of the coach are challenging for every sensing counter. At least two cameras are needed to avoid people hiding one another. In turn, this requires a robust solution that avoids double counts.

We also evaluated a 3D sensor to count people, but some trains only have a [ceiling] height of 2.1m, so [...] you can't be precise with just one sensor. People 1.9m tall will hide others with 1.6m. That's why it's crucial to work with multiple cameras.

Another hitch was to provide continuity for changing looks. A passenger-meter must not be derailed by people entering with, e.g.,

  • a cap or hoodie pulled deep down that they later remove,
  • an umbrella held above their head which they fold away as they step in,
  • a winter coat that has a fur-trimmed hood they drop once in the warm carriage, or
  • skis, bikes, or a lot of luggage.

We identified such cases and trained our learning AI algorithms accordingly. Thus, allowing them to adapt and discern that people remain the same despite altering appearances.

What’s next?

 

Having determined traveler numbers in single carriages with two entrance foyers and four doors, the next logical step is now to deploy the solution on the entire train. And to hone, sharpen and refine our AI models to further increase the precision and squeeze out the remaining errors.

Privacy and data protection

 

Both SBB and Parquery are very sensitive to privacy and data protection and guarantee to process no personal data. The data relevant to SBB are anonymized head counts.

With the counting done in the entrance area, there was no need to monitor the entire carriage and its passengers at all times. Moreover, the team took special care to reduce the image resolution so people cannot be recognized.

 

What happens onboard stays onboard

 

Parquery's solutions also run on edge devices. Edge devices are powerful tiny computers that can be installed onboard near the camera, such as the NVIDIA Jetson Xavier NX. Thus, all image and video analysis can be done onboard the vehicle and deleted once processed. No image or video data ever leaves the train.
