Measuring and Modeling Behavioral Decision Dynamics in Collective Evacuation
Figure 7
The distributions of evacuations as a function of 
.
Frame A shows the numbers of evacuations at each of the eleven values of 
. The distribution is peaked at 
. Frame B presents the normalized cumulative evacuation curves with individuals shown in blue and the population as a whole (the running sum of the distribution in A) in black. This provides a summary of the heterogeneity in evacuation decisions. Frame C shows the evacuations for each individual participant. Here we illustrate results for the highest scoring participant at the top and the lowest scoring participant at the bottom. We see a trend that the higher scoring participants evacuated more consistently at 
, and the lowest scoring individuals have greater spread in the 
values at which they evacuated. Frame D gives the cumulative evacuations, a running sum of the data presented in C. We see that higher scoring individuals evacuate more readily, with the noted exception of the fourth worst scoring participant, who tended to evacuate much earlier than the others; a strategy that resulted in many unsuccessful evacuations.
