Integrated modelling of business processes and real time communication for public transport: Modelling connection protection with business process model and notation

This paper proposes a generic communication system, which is controlled by a formalized process model. This system architecture is instantiated for the public transport domain. The operation of this system combines a distributed work-flow model (Business Process Modell and Notation, BPMN) with open communication standards incorporating real time communication (RTC) characteristics as provided by e.g. LTE mobile IP networks. The performed formalization meets the requirements of a typical scenario in public transport: connection protection. The participants involved are represented by the control center, along with the mobile and distributed users: drivers and passengers. Formalization with BPMN allows the modelling and understanding of the various interactions and communications between the different agents. For public transport operators the approach set out in this paper leads to a considerable economic advantage. Passengers benefit from improved customer experience in seamless travel across different modes of transportation.
