If your simulation includes vehicles you need to load an Aimsun XML file when opening project files in order to display the vehicles. This XML file contains all vehicle positions over time and enables LEGION Simulator to visualise traffic.

When loading project files, using the ‘Open Project Files’ (dialog, you can now check the box labelled ‘Load Aimsun simulation result file’, click the adjacent Browse button and navigate to the appropriate Aimsun XML file.

With vehicle positions loaded, LEGION Simulator can display traffic as part of the simulation.
