Using Attractors for Better crowd management

Disclosed is the method on the use of attractors to better manage and control crowd movement so people can get to a final destination point in a more efficient, safe, and orderly manner. Attributes of attractors are as follow:

An attractor is a trigger that creates a navigation path that was not previously scheduled such that the direction of the navigation may be "pulled" toward, or "pushed" away from particular navigation nodes.

An attractor in one navigation path may trigger a new and previously unscheduled navigation path to be created for a different entity, or navigational device.

The navigation path in one navigation device may also trigger an attractor, with either a "push" or "pull" to be activated in another navigation device.

An attractor may be a forward attractor, having a "pull" direction toward a particular direction.

An attractor may also be a reverse attractor, having a "push" direction away from a particular direction.

Different route segments may have different attractors, such that one segment may have a "push" attractor away from a particular node,

whereas the next segment may have a "pull" attractor toward a particular node.

The strength of an attractor may vary along the direction that it follows, meaning that the attractor strength may be stronger near one node and weaker closer to the opposite node. For example, a "push" may be stronger as one gets closer to a particular node in a navigation unit, and weaker as one gets away from that node.

The combination of "push" and "pull" attractors in the navigation nodes may cause a change of direction along the navigation path. This interaction may direct the navigation path toward the intended and desired location.

In some cases, an attractor may cause a previously nonexistent navigation path to be created, and request that navigation be initiated at a particular time.

Each device navigation path has a priority. This determines the route of a particular navigation path, which may gravitate either toward or away from certain nodes of a different navigation path in a different navigation device.

An attractor may be made to automatically be triggered as a result of events, or be triggered by direct intervention. At a given moment, how a particular sub-group of people is affected by the same set of events may differ from how others are affected by those same events, even though events may occur at the same time.

The attractor paths and destinations are dynamic in nature.

Example Embodiment #1: With attractors on navigational devices, the initial plan was for user1 to pick up user2 at point A and meet user3 at point D. Because of an unexpected situation, people at point A needed to be evacuated and traffic restricted for areas east and southeast of point A. These restrictions mean user1, user2, and user3 can no longer meet at point D, so navigation is being "pushed" away from point D.
