HUMOS 2 model is developed under a European Framework program and used in numerous publications since early 2000's. Unfortunately, I could not find a reference on how the model it self can be accessed. Any help is appreciated.
that presented an introductory work (http://www-nrd.nhtsa.dot.gov/pdf/esv/esv17/Proceed/00129.pdf) with some details at one of the past NHTSA Conference.
I did send him an email. I was thinking it should be owned by IFSTTAR but searching their website does not turn anything. I found some webpages about ESI providing Humos model. I will check with them as well.
