This paper examines a transportation model which is to be used as a support in planning and whose main requirement is general applicability in terms of both geographical area and user levels. The model treats the transport network as a system of finite elements characterized by a transit delay. These elements are nodes, legs or links, and carries. The model consists of a series of cores, each of which applies to a different commodity. Integration in the network takes place on the legs at carrier level. The elements of each core characterized by both operational and economic performance. The dynamics run on two times scales: day-to-day and year-to -year. The model is implemented by discrete-event, object-oriented languages and provides a scenario for decision-making problems, which are typically approached using System Dynamics methods.
