Experiments and results from the paper

This page contains all the results for the experiments described in the paper

Experiment 1 results - Effect of number of people in space

Aim was to check how the social distancing metric and risk metric change with number of people in the room. We simulate N people walking towards each other startingfrom points along the circumference of a circle of radius 8m.They stop when they are 1m away from each other and returnto their original position. Multiple such simulations are runwith different values of N. We used N = 2, 4, 10 and 30 peo-ple. This experiment shows how the social distancing metricand risk metric vary when number of people and distancesbetween them varies.

Experiment 2 results - Effect of time spent in same location

The aim of this experiment is to show howthe social distancing and risk metrics vary when N people re-main in the same position for time T, for example when theyare sitting in a class room. We set N=5 for all the experi-ments. We place the 5 people along the circumference of acircle of radius D, where we vary D. We use D = 1m, 2m,6m and 10m. The 5 people are at the same position for T =50 seconds. For each of the D’s we run separate experimentswhere the distance between people is varied.

Experiment 3 results - Effect of time spent in same location

In this experiment, we simulate people mov-ing in the EP6 setting. We show how the social distancingand risk metrics change as people move around this space.We simulate 30 people moving between different rooms in the space.
