This paper presents the actor-based freight transport simulation system InterLOG, which is constructed for mapping transport logistics decisions of shippers and transport companies that interact in transport markets and maximize their profits. It integrates methodological elements from logistics science, tour-planning algorithms and modeling techniques from the economics of networks to achieve a fully microscopic simulation of a large number of truck movements on infrastructure networks. The model consists of several modules. The generation and sourcing modules apply a Monte Carlo simulation. The market interaction modules use an agent-based modeling approach, which is influenced by the principles of network economics. The modeling system makes explicit the different decision situation of heterogeneous actors and the emergence of truckload and less-than-truckload transport (ad-hoc) networks. The InterLOG prototype is especially designed as a system that can be adapted to large simulation tasks in order to produce statistically reliable traffic charge patterns in large networks and planning regions. The focus of the paper lies on a technical description of the modeling system’s architecture; however, also the motivation for actor-based freight transport modeling, it properties, some exemplary application cases and the limits of the microscopic rule-based approach are shown.
