Let’s further assume that the exit is located at $(0,0)$. Then we may describe the pedestrian’s position with the following differential equations: $$ \dot{x} = ...

An attractor is defined in phase space. Phase space is the space of all degrees of freedom of your system. So in your example it cannot be a spatial location such as a room exit. Instead you have to imagine how many parameters describe the motion of one person (a lot), then how many persons there are, multiply the two and you will get the size of phase ...
