“…The walking direction of the participants in five runs of the congested condition is clockwise and in other runs is counterclockwise. During the experiments, the participants wore dierent colored hats to indicate their body height, ranging from 1.38-1.70 m. Thus, the trajectories of their heads could be extracted more accurately by PeTrack taking the perspective distortion into account [22][23][24]. A marker on the hat further increases the accuracy of the resulting trajectories [25].…”

Stepping locomotion is the basis of human movement. The investigation of stepping locomotion and its affecting factors is necessary for a more realistic knowledge of human movement, which is usually referred to as walking with equal step lengths for the right and left leg. To study pedestrians’ stepping locomotion, a set of single-file movement experiments involving 39 participants of the same age walking on a highly curved oval course is conducted. The microscopic characteristics of the pedestrians including 1D Voronoi density, speed, and step length are calculated based on a projected coordinate. The influence of the projection lines with different radii on the measurement of these quantities is investigated. The step lengths from the straight and curved parts are compared using the Kolmogorov–Smirnov test. During the experiments, six different step styles are observed and the proportions of different step styles change with the density. At low density, the main step style is the stable-large step style and the step lengths of one pedestrian are almost constant. At high density, some pedestrians adjust and decrease their step lengths. Some pedestrians take relatively smaller and larger steps alternately to adapt to limited space.
