I found this model a few months ago, its quite good as it shows how pedestrians exit a building when a fire is spreading through it. The model is written in Repast and makes use of .xml and txt files. While it is extremely basic, the model highlights how ABM can be utilized to examine emergency egress from a building. On a side note, CASA has a long history of pedestrian modelling using ABM (Click here to see more along with checking out the CASA working papers)
Unfortunately I don’t remember where the original source code came from but if you wrote it please let me know so I can give you full credit.
