The rapid growing of applications of Advanced Transport Telematic (ATT) systems in recent years is generating an increasing request for tools to help in system design and assessment. Microscopic traffic simulation has proven to be one of the most useful tools to achieve these objectives, and thus microscopic traffic simulation has become an ever increasing field of research and development. The development of a microscopic traffic simulator represents a double challenge: traffic and network modeling on one hand, and how to embed the models in a software platform interfacing the user in a friendly and efficient way. This paper summarizes the most relevant concepts in microscopic traffic simulation, and how they have been implemented in AIMSUN2. Other applications of microscopic traffic simulation can be envisaged provided the computing time can be shortened properly. For large scale models parallelization appears to be a natural way to achieve such speeding-up objectives. The paper concludes by describing the parallelization approach used and presenting the first computational results of the parallelization of AIMSUN2
