1. A method comprising:
- a mobile device traveling in a vehicle determining a geographic location of the mobile device and using the geographic location of the mobile device to determine whether to initiate scanning for Bluetooth devices wherein using the geographic location of the mobile device to determine whether to initiate scanning for Bluetooth devices comprises comparing the geographic location of the mobile device to each of a plurality of work zone areas using parameters describing the geographic extent of the plurality of work zones that are stored in the mobile device and changing from having scanning for Bluetooth devices disabled to enabling scanning for Bluetooth devices when the mobile device enters one of the work zone areas;
after initiating scanning, the mobile device detecting a Bluetooth device and determining that the Bluetooth device is a work zone tag;
the mobile device issuing a warning that indicates that the vehicle is near a work zone based on the work zone tag;
the mobile device determining a speed of the mobile device, comparing the speed to a speed provided for the work zone tag and issuing a speeding alert when the speed of the mobile device exceeds the speed provided for the work zone tag; and
the mobile device disabling scanning for Bluetooth devices when the mobile device leaves a work zone area.

Abstract
A method includes a mobile device traveling in a vehicle scanning for Bluetooth devices. When the mobile device detects a Bluetooth device, it then determines that the Bluetooth device is a work zone tag. The mobile device then issues a warning that indicates that the vehicle is near a work zone based on the work zone tag.

6. A method comprising:
-
scanning for Bluetooth-enabled devices in a work zone using a first device; detecting a Bluetooth-enabled device in the work zone using the first device; displaying a user interface on the first device that includes a control to designate whether a mobile device in a vehicle in the work zone should trigger speeding warnings when the mobile device detects the Bluetooth-enabled device and that accepts a speed value and a warning message designated by a user of the first device that indicates that the vehicle is near a work zone based on the Bluetooth-enabled device to be conveyed by a mobile device when the Bluetooth-enabled device is detected by the mobile device; sending the speed value and the message accepted through the user interface and an identifier for the Bluetooth-enabled device from the first device to a database on a network so that the speed value and the message can be forwarded to the mobile device by a server that accesses the database. - View Dependent Claims (7, 8, 9, 10)

11. A mobile device comprising:
-
a memory storing; an alert received from a server database that received the alert from a user device wherein the alert is associated with a Bluetooth-enabled device and is stored in memory before the mobile device has detected the Bluetooth-enabled device, the alert indicating that the mobile device is in a work zone; geographic descriptions of a plurality of work zones; a Bluetooth communication module that receives a Bluetooth communication signal from the Bluetooth-enabled device; an output device; a position module that provides information describing a geographic position of the mobile device and that provides a speed for the mobile device; and a processor that; enables the Bluetooth communication module scanning upon determining that the geographic position of the mobile device is within one of the plurality of work zones and disables the Bluetooth communication module scanning upon determining that the geographic position of the mobile device is outside of all of the plurality of work zones; based on the Bluetooth communication signal triggers the output device to generate the alert; and accesses a speed value associated with the Bluetooth-enabled device, compares the speed value to the speed of the mobile device, and generates a speeding warning when the speed of the mobile device exceeds the speed value. - View Dependent Claims (12, 13, 14)
