Passenger Flow

Dear all,

I was wondering if there is any grasshopper plug in for Rhino ( ideally free) that can simulate passenger flow like Cast Modelling or results like Cast express for stations, airports and similar complex public spaces…

I saw quelea, flow ( payment), but I would like your opinion regarding the best software, plug-in for such exercises.

Any help very much appreciated.
