General Behaviour
In general terms humans are divided into households. Each person ‘belongs’ to a household to which it returns each night (generally speaking). Humans are further divided into ‘workers’ and ‘home-stayers’. Worker humans go to their assigned work zone every day for a predetermined amount of time. Humans can be also programmed with a certain probability of visiting other households.

Routines
Movement
As mentioned in the overview humans can move in a targeted or random pattern. Even the targetted movement can have a given amount of “noise” added to cover scenarios in which humans do not go straight to a given location.
Behaviours
Wander Behaviour
People can be set to move around a given place to mimic children playing around a house or persons that stay at home taking care of their house.
Working Behaviour
Another behaviour that can be activated is the one of people that go to a definite location to work.
Visiting Behaviour
Humans can be allowed to visit other houses if required. For now the simulation has two implemented visiting behaviours.
Random
This routine selects a household at random from the pool of houses with a uniform distribution of probabilities.
Targetted
We have also included a targetted movement routine in our ABM. This routine is coded as a gravity model in which the probability of visiting a household depends on the areas of the houses over the distance between them. These probabilities are static and calculated when the map is detected from Google Maps. They are exported in the house objects.
