Pedestrians walking in crowds show complex dynamics and stunning collective motion.
\nThe investigation of the underlining behaviors from single individuals to large-scale interactions is the topic of our research.<\/p>\n
The typical questions we challenge ourselves with are<\/p>\n
- \n
- Can we write quantitative models for the behavior of pedestrians walking in crowds?<\/strong><\/li>\n
- Are pedestrian crowds moving like fluid flows?<\/strong><\/li>\n<\/ul>\n
Answers to these questions has primary impact in engineering, as they enable accurate evacuation simulations, crowd management and interactive built environments.<\/p>\n

Walking individuals have an intrinsically random behavior. A quantitative prediction of walking trajectories is thus impossible. Nevertheless, we expect walking pedestrians to exhibit universal features at the statistical level. In other words, we expect the distributions of position, velocity or acceleration to describe the dynamics.
\nComparison with measurements is paramount to shed light on this aspect. Hence, we perform extensive and highly accurate experimental measurements of pedestrian trajectories. To explore the statistical portrait including the rare events we perform 24\/7 automatic data acquisition on a yearly basis. We established different measurement locations within TU\/e<\/a> [1, 2] and at Eindhoven Train Station<\/a> (cf. Figure 1 and 2).<\/p>\n![\"\"](\"http:\/\/crowdflow.phys.tue.nl\/wordpress\/wp-content\/uploads\/2017\/08\/station_tracks-1024x589.png\")
