Insight into actual passenger numbers using computer vision

To understand the total number of passengers on its vehicles, GVB carries out manual counts. This work is labour-intensive, prone to error and provides only a snapshot. We developed software for GVB that can take over this task. Using computer vision and footage from a vehicle’s security cameras, it can count passengers. The footage is not viewed or shared; it is only analysed by the model. This protects passengers’ privacy. The solution gives GVB insight into actual passenger numbers over a longer period, so it can act on what the data shows. For example, GVB can see which routes have more passengers travelling without paying.  

It has been a challenging project that has taught us a great deal about innovating with data while keeping things practical. Collaboration between experts from different fields shows what is possible.
