and a database that stores instructions that, when executed by the processor, cause the processor to determine a speed, a direction of travel, and a geographic location of a mobile device, store route data identifying a route traveled by the mobile device, determine that a traffic condition exists on the route traveled based upon the route data, the geographic location, the direction of travel, and the speed of the mobile device, in response to determining that the traffic condition exists on the route traveled, transmit, to the mobile device, a notification for presentation at the mobile device, the notification indicating the traffic condition and a location of the traffic condition, and determine a code value indicating drivability for the route traveled. ### Claim 2 (depends on 1) The traffic advisory system of claim 1, wherein the traffic condition comprises a traffic incident. ### Claim 3 (depends on 1) The traffic advisory system of claim 1, wherein the traffic condition comprises traffic congestion. ### Claim 4 (depends on 1) The traffic advisory system of claim 1, wherein the instructions further comprise instructions that, when executed by the processor, cause the processor to receive input from the mobile device, the input corresponding to a request for alternative route information. ### Claim 5 (depends on 1) The traffic advisory system of claim 1, wherein the instructions further comprise instructions that, when executed by the processor, cause the processor to receive input from the mobile device confirming that the mobile device is in transit and that relevant driving-condition updates are to be transmitted to the mobile device. ### Claim 6 (depends on 1) The traffic advisory system of claim 1, wherein the instructions further comprise instructions that, when executed by the processor, cause the processor to transmit the notification using an audio message. ### Claim 7 (depends on 1) The traffic advisory system of claim 1, wherein the instructions further comprise instructions that, when executed by the processor, cause the processor to transmit the notification using a text message. ### Claim 8 A non-transitory computer readable medium having stored thereon computer-executable instructions that, when executed by a processor, cause the processor to: determine a speed, a direction of travel, and a geographic location of a mobile device; store route data identifying a route traveled by the mobile device; determine that a traffic condition exists on the route traveled based upon the route data, the determined geographic location, the direction of travel, and the speed of the mobile device; in response to determining that the traffic condition exists on the route traveled, transmit a notification for presentation at the mobile device, the notification indicating the traffic condition and a location of the traffic condition, and determine a code value indicating drivability for the route traveled. ### Claim 9 (depends on 8) The non-transitory computer readable medium of claim 8, wherein the traffic condition comprises a traffic incident. ### Claim 10 (depends on 8) The non-transitory computer readable medium of claim 8, wherein the traffic condition comprises traffic congestion. ### Claim 11 (depends on 8) The non-transitory computer readable medium of claim 8, wherein the instructions further comprise instructions that, when executed by the processor, cause the processor to receive input from the mobile device, the input corresponding to a request for alternative route information. ### Claim 12 (depends on 8) The non-transitory computer readable medium of claim 8, wherein the instructions further comprise instructions that, when executed by the processor, cause the processor to receive input from the mobile device confirming that the mobile device is in transit and that relevant driving-condition updates are to be transmitted to the mobile device. ### Claim 13 (depends on 8) The non-transitory computer readable medium of claim 8, wherein the instructions further comprise instructions that, when executed by the processor, cause the processor to transmit the notification using an audio message. ### Claim 14 (depends on 8) The non-transitory computer readable medium of claim 8, wherein the instructions further comprise instructions that, when executed by the processor, cause the processor to transmit the notification using a text message. ### Claim 15 A traffic advisory system comprising: a processor; and a database that stores instructions that, when executed by the processor, cause the processor to determine a speed, a direction of travel, and a geographic location of a mobile device, store route data identifying a route traveled by the mobile device, determine that a traffic condition exists on the route traveled based upon the route data, the geographic location, the direction of travel, and the speed of the mobile device, in response to determining that the traffic condition exists on the route traveled, transmit, to the mobile device, a notification for presentation at the mobile device in a graphical user interface presenting a map and visual representation of the route, the notification indicating the traffic condition and a location of the traffic condition on the map, and determine a code value indicating drivability for the route traveled. ### Claim 16 (depends on 15) The traffic advisory system of claim 15, wherein the instructions further comprise instructions that, when executed by the processor, cause the processor to receive input from the mobile device, the input corresponding to a request for alternative route. ### Claim 17 (depends on 15) The traffic advisory system of claim 15, wherein the instructions further comprise instructions that, when executed by the processor, cause the processor to receive input from the mobile device indicating that driving-condition updates are to be transmitted to the mobile device. ### Claim 18 (depends on 15) The traffic advisory system of claim 15, wherein the traffic condition comprises traffic congestion, and wherein a location of the traffic congestion is indicated on the map displayed at the mobile device.
