we made a proposal to integrate hawkers into pedestrian facilities ( walkways) since their existence cant be ignored for no more ( In India, hawkers encroaches walkways to sell the goods like food, articles etc for pedestrians and motorists..)

We found some case studies to integrate them into walkways ( singapore, Europe ).
We would like to go for a pedestrian simulation for the current situation and would like to compare with the future scenario ( after incorporating the designed facilities and restrictions on hawkers)

My question is What are the Steps Involved/ what parameters do I need to Simulate with VISSIM ( since our organization have this tool)?

How about finding the qualitative LOS is helpful for my studies..?

Thanks in Advance
