Story summary
- Researchers found passengers at Eindhoven Centraal follow the person ahead even when it adds travel time.
- They built an algorithm that identified and excluded proximate groups to isolate individual walkers.
- Sensors recorded 30 million trajectories on a 1,400 m² area at 10 fps from March 2021 to March 2024.
- The model reproduced avalanche patterns only when it incorporated the stranger-following effect, leading authors to conclude such interactions shape crowd dynamics.
