A method for managing a training arena for training an operator of a host vehicle includes the procedures of generating a training arena model, updating the training arena model according to gathered real time training arena data, and managing the selected virtual entity for simulating a real entity. The training arena model is updated according to the selected virtual entity data, deriving from the training arena model an operator arena model, producing a representation of the operator arena model. The representation of the operator arena model is presented to the operator and the selected virtual entity is managed according to the training arena model as would have been detected and as could have been perceived by the selected virtual entity were the virtual entities real.
