Integrated Modelling of Business Processes and Communication Events for Public Transport

In this paper, a generic communication system, which is controlled by a formalized process model is proposed and instantiated for the public transport domain. The operation of this system combines a distributed work-flow model (Business Process Modelling Notation, BPMN) with open communication standards such as 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 control centers, along with the vehicle users: driver and passengers. Formalization with BPMN allows the modelling and understanding of the different interactions and communications between the different agents. For public transport operators the approach set out in this paper leads to a considerable advantage regarding economic requirements.
