From the Massachusetts Institute of Technology, American scientists have found that the transition from the sequential movement of the crowd to chaotic movement emerged when the average deviation angle of pedestrians was higher than a certain value. Discovery can revolutionize the design of public spaces. The study was published scientifically magazine National Academy of Sciences (PNA) procedures.
The team combined mathematical modeling based on hydrodynamic equations and experiments with volunteers in a controlled environment.
The results showed that the crowd was turned into clear lines with a less angular spread of less than 13 °. However, with more than 13 °, a chaotic movement occurs with frequent conflicts. Flow activity is reduced by 20-30% with error.
According to scientists, the “Rule 13 °” will help design safer and more effective airports, stations and pedestrian zones, and will also provide a tool to manage the crowd in mass activities.
“This is just like a boiling point for human flows, Prof said Professor Karol Bachik, the head of the study.
Previously, scientists provenAnts are superior to the people who work for collective actions.
