In particular, some authors (Castle et al., 2011) have compared the use of STEPS (a Cellular Automata model) with
LEGION. The authors conclude that both models get good results, however LEGION is more realistic than STEPS because it
is based on a continuous movement algorithm rather than grids. Similarly, Alexanderson and Johansson, 2013 have compared
VISWALK (a Social Force Model) with LEGION. They state that both models simulate the interaction with other modes
of transport; however VISWALK is better than LEGION for in-depth analyses. In this sense there is not an ultimate software
