To gain insight into the total number of passengers in vehicles, GVB conducts manual counts. This work is labor-intensive, prone to errors, and only provides a snapshot in time. With GVB, we developed software that can take over this task. By utilizing computer vision in combination with footage from the security cameras in a vehicle, the number of passengers can be counted. The footage is not viewed or shared but is only analyzed by the model, ensuring privacy is maintained. With this solution, GVB can achieve actual insights into passenger numbers over a longer period, allowing them to respond to these insights. For example, they can identify which lines have a higher number of non-paying passengers.
