A concept for interoperability of security systems in public transport

In the field of public transport, operators and first responders collaborate in the prevention of and reaction to security issues. In order to optimise their specific daily operational business needs in a timely manner heterogeneous information and communication systems are deployed. In case of an incident however it is crucial that the various involved parties exchange relevant information to develop a shared understanding and act in a coordinated way. Yet, heterogeneous communication and information system infrastructures often hinder this crucial flow of information. To address this shortcoming it is crucial to enable the design of interoperable system-of-systems approaches in this domain. This paper describes a conceptual model to construct system-of-systems environments in the domain of security in public transport. By building on the results of several European research projects this concept offers a starting point for modelling and documenting individual systems inside a system-of-systems architecture.
