Abstract:

APC systems and methods using vehicle mass to assess boardings and alightings of passengers on transit vehicles (e.g., buses). Vehicle mass is determined based on signaled information indicative of a pressure in one or more air bag circuits of an air ride suspension system of the vehicle. In some embodiments, pressure information from three air bag circuits of the vehicle are monitored and reviewed to determine vehicle mass. The passenger count can be estimated based on determined vehicle mass by an Additional Mass Method or an Event-Based Method for example.
