Abstract

Systems, methods, and apparatuses are provided for storing and accessing traffic data images in a limited bandwidth environment. A traffic map image database is stored in a navigation device, where the database includes a plurality of traffic map images. A traffic condition is determined for a location of the navigation device. A traffic map image is retrieved from the database using a processor, where the traffic map image reflects the traffic condition for the location of the navigation device. The traffic map image is displayed on the navigation device.

Claims

1. A method comprising:

determining a real-time traffic condition for a location;

comparing, using a processor, the real-time traffic condition with a server database comprising a plurality of traffic map images;

selecting a traffic map image from the server database to represent the real-time traffic condition, the traffic map image having an identification key associated with the traffic map image; and

transmitting the identification key to a navigation device having a navigation device database comprising the plurality of traffic map images, wherein the navigation device is capable of retrieving the traffic map image from the navigation device database for display.

2. The method of claim 1, wherein the navigation device is in communication with the processor, wherein the navigation device relays a device signal to the processor;

and

wherein the processor relays the identification key to the navigation device based on the real-time traffic condition and the device signal of the navigation device.

3. The method of claim 2, wherein the device signal comprises a geographic location of the navigation device.

4. An apparatus comprising:

at least one processor; and

at least one memory including computer program code for one or more programs;

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least perform;

determine a real-time traffic condition for a location;

compare the real-time traffic condition with a server database comprising a plurality of traffic map images;

select a traffic map image from the server database to represent the real-time traffic condition, the traffic map image having an identification key associated with the traffic map image; and

transmit the identification key to a navigation device having a navigation device database comprising the plurality of traffic map images, wherein the navigation device is capable of retrieving the traffic map image from the navigation device database for display.

5. The apparatus of claim 4, wherein the navigation device is in communication with the processor, wherein the navigation device relays a device signal to the processor;

and

wherein the processor relays the identification key to the navigation device based on the real-time traffic condition and the device signal of the navigation device.

6. The apparatus of claim 5, wherein the device signal comprises a geographic location of the navigation device.
