Pedestrian Dynamics: Feedback Control of Crowd Evacuation (Understanding Complex Systems)

Pedestrian Dynamics: Feedback Control of Crowd Evacuation (Understanding Complex Systems), 9783540755593 (3540755594), Springer, 2008

The importance of controlling pedestrian flow especially during emergencies is being understood by researchers to be a very important research area. Currently, the use of static emergency routes is not efficient, since during emergencies, the preferred routes might be congested, or worse yet might not even exist. Hence, it is very important to use sensors to measure the current traffic and conditions on the routes and give real-time guidance to pedestrians using feedback control. This book is the first book that provides feedback control design for pedestrian movement control in one and two-dimensional problems using lumped and distributed parameter model settings. There is much more development that is needed in this important work, but the authors hope that this book provides inspiration for other researchers to continue work in this area.

Evacuation can be from a small area, single floor of a building, a entire building, a parking area, or from a much bigger region such as an entire city. The feedback control design for evacation of pedestrians in small areas falls under the framework presented in this book. Evacuation from bigger regions such as a city requires vehicular traffic control from highways, which can involve modeling of networks using digraphs. Network control for evacuation is not covered in this book.

Effective evacuations can save lives. This book provides mathematical models of pedestrian movements that can be used specifically for designing feedback control laws for effective evacuation. The book also provides various feedback control laws to accomplish the effective evacuation. It book uses the hydrodynamic hyperbolic PDE macroscopic pedestrian models since they are amenable to feedback control design. The control designs are obtained through different nonlinear techniques.
