Abstract

In determining whether to provide an alert associated with a mobile element to a mobile communication device, speeds and directions of travel of the mobile element and the mobile communication device are determined. A relative location of the mobile communication device is calculated with respect to the mobile element. Based on the relative location of the mobile communication device with respect to the mobile element, a determination is made whether the alert should be provided.
