BACKGROUND Modelling travel time to services has become a common public health tool for planning service provision but the usefulness of these analyses is constrained by the availability of accurate input data and limitations inherent in the assumptions and parameterisation.

Formal modelling provides valuable intellectual tools which can be applied to the problem of analysis and optimisation of systems. In this paper we present a novel software tool which provides a graphical approach to modelling of Collective Adaptive Systems (CAS) with constrained movement. The graphical description is translated into a model that can be analysed to understand the dynamic behavi...
