SUMS: Sutherland -- Pedestrian dynamics (or Why you want to punch slow moving people in the back of the head)

This week’s talk:

"Duncan Sutherland is perpetually irritated by annoying pedestrians getting in
his way. To understand the mathematics behind modelling pedestrian dynamics,
he consulted google and found the following paper: Burstedde, C. et al.
”Simulation of pedestrian dynamics using a two-dimensional cellular
automaton”, Physica A, (2001) 507-525, which he decided to discuss in a SUMS
talk.

This talk will introduce the basic concepts of cellular automata, and will
discuss the model of Burstedde et al. A pedestrian is modelled as a particle
which makes a transition between cells with some probability p_ij. The most
interesting feature of Burstedde’s model is the concept of a floor field. The
floor field modifies the probabilty p_ij. A static floor field is used to
model topological features such as walls and doors, and also features which
are attractive or repulsive to pedestrians, such as emergency exits or fires.
A dynamic floor field changes with the pedestrian flow and is used to model
long range interactions."

Usual time, usual place, unusual speaker. I highly recommend coming.
