New areas of application of traffic micro-simulation models arecurrently being explored. Examples include analysis of IntelligentTransportation Systems, safety assessments and vehicle emissionsstudies. Many of these new applications depend on reliable andrepresentative simulated vehicle trajectories. The traffic simulationmodels used for these applications must therefore modeldriver/vehicle behavior with greater detail than what is necessaryfor traditional traffic engineering applications. In this paper,we argue that this increased model complexity may reducethe applicability of the models to other situations with differentdriver/vehicle behavior. Such situations include simulation of trafficin different countries or regions as well as simulation of roadenvironments with different properties. The objective of the paperis to bring focus to modeling considerations that are important fortoday’s increasingly detailed traffic micro-simulation applications.Model application to traffic in different regions is exemplified by acase study in which the Rural Traffic Simulator developed in Swedenis applied to simulation of traffic on a Dutch two-lane highway.Simulation of traffic in different regions and new model applicationsis to a certain extent facilitated by the model calibrationand validation. The high level of detail of micro-simulation modelsmay however require use of different modeling assumptions for different applications. Advances in vehicle trajectory measurementtechniques will allow developments of more detailed traffic microsimulationmodels. It is therefore increasingly important that themodels are estimated and cross-validated using data sets that arecollected in the regions and traffic conditions that the models aredeveloped for.
