Figure 14.5 Spatio-temporal variation of visitor flows during the Ghent Festivities 2011.
Four snapshots show the cumulative flows during four time windows of 30 minutes. The
outer border delineates the official event zone where specific regulations are in order to
make the event as safe as possible. The direction of an arrow indicates the direction of the
flow; the width of the arrow indicates its size. The widths of the arrows are normalized to
the size of the largest flow during each time period separately, so flows from other time
windows cannot be directly compared based on this visualization.
are depicted - each depicting the cumulative flows over 30 minutes. In the
afternoon (Figure
14.5
a), visitor flows are quite evenly spread over the event
zone, except for the area in the northeast depicted by the rectangle. Most of
the large flows are balanced in their directionality, but the flows in the perifery
are mainly inward oriented. Visitors regularly venture further from the center
across the Leie and Lieve rivers (depicted by the oval in the west of the event
zone). In the evening (Figure

b), the region in the Northeast has clearly
