In this paper we present a computational environment called LINUM for agent-based modelling, based on a geospatial transport model similar to the one implemented in ORBIS, The Stanford Geospatial Network Model of the Roman World. We provide the implementation of the transport model, and tools
for creating and analyzing agent-based models around it. We also provide web-based visualization of the results of the simulation, and enable the user to generate time-collapsed static network for further analysis by the means of complex networks measures. The functionality of the environment is
demonstrated on a model of diffusion process on the transport network.
