Most of the local public transit companies have vehicle monitoring systems able to collect huge quantities of data in real-time. Typically, these data are used to measure the performance of the transportation system, and rarely they are fully exploited to improve it and to tackle disruptions. In this report we take into consideration the case of the management of urban surface lines of Azienda Trasporti Milanese (ATM) of Milan. We discuss different ways to assess the regularity of the service, pointing out possible pitfalls of the currently used index of regularity. We present a delay and disruption management system describing technical details and the preliminary setting phase.
