Stamping Out Human Stampedes

Hardly a year passes without news of a major stampede in which people die because of dangerous bottlenecks or unexpected obstacles that obstruct crowd movement. Working with a number of public and private sector partners, engineers and computer scientists at the Technical University Munich (TUM) have created a crowd simulation program that they hope will help prevent such disasters.

Even supposedly minor obstructions can have a major impact on crowd dynamics. We can use the program to run any number of ‘what-if’ simulations. We know, for example, that crowd formation varies in the event of a bottleneck depending on the width of a passage or route. We also know that people tend to follow other people.”

To help make emergency management considerably easier, the program is able to compute evacuation scenarios for major events at various venues by simulating the behavior of crowds numbering into the thousands. According to the TUM announcement, “Color-coded crowd densities and real-time simulations make it a particularly user-friendly application, especially as conventional microscopic simulations usually require a long time to compute.”

Top 10 Emerging Technologies

Top 10 Technologies
Gearing Up for Science-based Change: A list of important future technologies that it predicts will impact the world has been released by the World Economic Forum.

Intelligent technologies for adding value to information and handling “noisy data” are among the expected advances showcased in a list of “Important Technologies” that, according to the World Economic Forum’s Global Agenda Council on Emerging Technologies, are poised to alter the world. The list was produced by a group of experts representing many areas, including science, businesses, and public policy.

“Accelerating progress in science and technology has stimulated a new age of discovery, and many of the technologies identified by the council are critical to building a sustainable and resilient future.”

 — Sang Yup Lee, Council Chair Professor, Korea Advanced Institute of Science and Technology (KAIST)

In alphabetical order, the Council’s top 10 emerging technologies are as follows:

  • Enhanced Education Technology
  • Green Revolution 2.0 – Technologies for Increased Food and Biomass
  • High Energy Density Power Systems
  • Informatics for Adding Value to Information
  • Nanoscale Design of Materials
  • Personalized Medicine, Nutrition and Disease Prevention
  • Synthetic Biology and Metabolic Engineering
  • Systems Biology and Computational Modeling and Simulation of Chemical and Biological Systems
  • Utilization of Carbon Dioxide as a Resource
  • Wireless Power

While the Council members expect that technological progress in these areas could have major impacts on social, economic, and environmental issues, they also caution that their “safe and successful development is far from guaranteed.”
