Analysis of emergent patterns in crossing flows of pedestrians reveals an invariant of ‘stripe’ formation in human data
Fig 2
Illustration of a trial of crossing flow from our experiments.
Traces of all the pedestrians involved for a typical trial has been shown with expected value of crossing angle equal to 60°. Three different instances of the trial has been shown here viz. before crossing (T1), during crossing (T2) and after crossing (T3). The actual values of time frames are T1 = 2.3 sec, T2 = 6.55 sec and T3 = 10.8 sec from the beginning of the trial. The two groups of pedestrians are denoted by blue and red dots. The tails behind each of the dots are basically the distances travelled by the pedestrians in previous 1.25 sec.
