Pedestrian Patterns at Railway Platforms during Boarding: Evidence from a Case Study in Switzerland

Figure 3

Modelling the boarding clusters: (a) minimal bounding box (MBB); (b) minimal bounding ellipse (MBE); (c) minimal bounding horizontal box (MBHB). The grey shape represents the convex hull, i.e., the smallest convex polygon containing the points. The red shape represents the selected model ((a) MBB; (b) MBE; (c) MBHB). Alighting passengers are represented by bullet points; boarding passengers by triangles (left side of the door) and squares (right side of door).
