This is an open-source micro-multi-modal traffic simulation toolkit that can accurately simulate various traffic participants from cars to pedestrians. It is developed by the Institute of Traffic Systems at the German Aerospace Center (DLR), and has the ability to handle large-scale road networks. It supports multi-modal traffic simulation of motor vehicles, non-motor vehicles and pedestrians, and is equipped with tools for quick creation and editing of scenarios. It is suitable for applications such as traffic planning, autonomous driving, intelligent transportation, and environmental impact assessment.
