Monitoring the Number of Pedestrians in an Area: The Applicability of Counting Systems for Density State Estimation

Figure 4

Visualisation of the demand at both entrances (left) and cumulative number of pedestrians in the region (right), where (a) illustrates the symmetric demand case and (b) the nonsymmetric demand case. The solid line represents the inflow, while the dashed line indicates the outflow.
