Abstract
An event-triggered dynamic landmark creation system includes a management system and tracking devices attached to mobile objects. Each tracking device is configured to wirelessly transmit information pertaining to current time, identification and location of tracking devices, and status of mobile objects. The management system is configured to wirelessly communicate with each tracking device and is operable: to receive information transmitted from each tracking device; in response to occurrence of an initial event respecting status of a first mobile object, to create a non-physical dynamic landmark about the first mobile object relative to location of a first tracking device attached thereto; and in response to occurrence of successive subsequent events respecting location of a second tracking device attached to a second mobile object, to record a visit of the second mobile object within the dynamic landmark about the location of the first mobile.
