  This paper aims to investigate the disparities in pedestrian crossing
behaviors within static and dynamic crowds through experimental analysis.
First, the crossing trajectories of pedestrians in various crowd environments
were qualitatively observed. These trajectories have shown significant
discrepancies and the phenomenon of cross-channel formation within static
crowds was observed, a phenomenon similar to the evolution of human trails. To
quantitatively assess these discrepancies, metrics of behavior patterns and
swarm factor were introduced. Different behavioral patterns, including
anticipation and reaction behaviors in pedestrian motion, were observed.
Finally, through orthogonal velocity analysis, the variation trends of crossing
motions within static and dynamic contexts were revealed.
