Conventional APC systems normally fail under these conditions. The advanced method presented in this paper calculates the actual weight of the vehicle from the driving dynamics, traction and energetic data of the vehicle and the track geometry. The weight of the passengers is derived from the total vehicle weight and is used to estimate the number of passengers. A cost-effective system has been developed and validated. The theoretical concept has been first proven under artificial conditions and then validated during real service on a tramline in Budapest. References [1] B.
