- How can crowds be moved safely and efficiently?This is the first comprehensive introductory book in this field, summarizing the latest research results on management methods for this purpose. Explains everything from crowd sensing, behavior prediction through simulation, and risk assessment to crowd control methods. A must-read book for anyone involved in crowd management.[From the book “Introduction” (Katsuhiro Nishinari)]Crowd management can be said to be a field of research that has not been very familiar in Japan. Of course, crowd security is routinely used at large concerts, sporting events, exhibitions, etc., and crowd safety is maintained in a variety of ways. However, much of this comes from the accumulation of experience and the wisdom of experts, and it is hard to say that it is systematized scientifically. On the other hand, in recent years, the remarkable development of AI-related technology has dramatically improved the accuracy of analyzing images from cameras and other devices. Simulation technology for predicting crowd behavior is also progressing, and is now being used to design user flow lines in buildings and venues. Under these circumstances, it would be a timely and meaningful effort to compile the various wisdoms of the past into a new crowd management system. Starting with crowd sensing, predicting behavior through simulation, and scientifically organizing and standardizing everything from risk assessment to crowd control in one framework, it is expected to greatly contribute to crowd safety.[Main table of contents]IntroductionChapter 1 Overview of Crowd Management1.1 What is crowd management?1.2 About stakeholders and crowd information1.3 About Crowd Manager1.4 About the structure of this documentChapter 2 Characteristics of Crowds2.1 Qualitative crowd characteristics2.2 Quantitative crowd characteristicsChapter 3 Crowd Accidents3.1 Types of crowd accidents3.2 Examples and classification of crowd accidents3.3 Management role3.4 Crowd accidents that have occurred so far and their outlinesChapter 4 Risk Assessment4.1 Positioning of risk assessment4.2 Determination of risk level4.3 From risk assessment to crowd controlChapter 5 Crowd Sensing5.
