Simulation results under different scenarios. (a,c,e,g,i,k,m) is the change of the number of people visiting different interest points after the re-opening strategy is implemented. The black curve represents the number of people visiting under the situation of non-opening, and the red curve marks the number of people visiting after the re-opening strategy is implemented. (b,d,f,h,j,l,n) are the fitting results of the number of cases (green solid line) and the actual number of cases (black dotted line) obtained by the model when the reopening strategy was not implemented at each point of interest, as well as the changes of COVID-19 infection cases after the reopening strategy was implemented (red solid line).
