realistic evacuation model

i am trying to determine how to create a realistic model of an apartment building evacuation after a fire alarm has been triggered, and am wondering the best way to go about this. i'm hoping to effectively model the responses of different types of people (eg old and young, men, women, and children, those moving faster and slower etc). could the people all be modeled as various operators? the model run would come to completion once the building has been completely emptied. i'm not sure where to even start, so if anyone had any suggestions of how i might go about doing so, i'd certainly appreciate them!

Hi Danielle,

We have made a few models with people flows
Airport:
Stadium:

These models are all constructed with the use of a Person Flow Library that we have build. Let us know if you want more information. (www.talumis.com)
