Abstract

A communication device for providing road conditions and monitoring congestion, contains a memory and a processor configured by the memory to perform the steps of: extracting key current vehicle and/or traffic insight; determining if the extracted key current vehicle and/or traffic insight represents a departure from expected vehicle and/or traffic insight; if the extracted key current vehicle and/or traffic insight is a departure from expected vehicle and/or traffic insight, using the key current vehicle and/or traffic insight to create a smart message, wherein the smart message contains the extracted key current vehicle and/or traffic insight; and if the extracted key current vehicle and/or traffic insight is a confirmation of expected vehicle and/or traffic insight, creating a confirmation message that does not contain the extracted key current vehicle and/or traffic insight, yet confirms similarity between the extracted key current vehicle and/or traffic insight and the expected vehicle and/or traffic insight.

Claims

1. A communication device for providing road conditions and monitoring congestion, comprising:

a memory; and

a processor configured by the memory to perform the steps of;

extracting key current vehicle and/or traffic insight;

determining if the extracted key current vehicle and/or traffic insight represents a departure from expected vehicle and/or traffic insight;

if the extracted key current vehicle and/or traffic insight is a departure from expected vehicle and/or traffic insight, using the key current vehicle and/or traffic insight to create a smart message, wherein the smart message contains the extracted key current vehicle and/or traffic insight; and

if the extracted key current vehicle and/or traffic insight is a confirmation of expected vehicle and/or traffic insight, creating a confirmation message that does not contain the extracted key current vehicle and/or traffic insight, yet confirms similarity between the extracted key current vehicle and/or traffic insight and the expected vehicle and/or traffic insight.

2. The communication device of claim 1, wherein the communication device is physically connected to the current vehicle, but not electronically connected to the current vehicle.

3. The communication device of claim 1, wherein the communication device is in communication with the current vehicle through use of an on board diagnostics (OBD) or OBDII vehicle connection.

4. The communication device of claim 1, wherein the expected vehicle and/or traffic insight is previously extracted key current vehicle and/or traffic insight from the current vehicle.

5. The communication device of claim 1, wherein the expected vehicle and/or traffic insight is prior extracted key vehicle and/or traffic insight from other vehicles that were driving on a path that is the same as a path currently being driven by the current vehicle.

6. The communication device of claim 1, wherein a departure from expected vehicle and/or traffic insight is wherein extracted key current vehicle and/or traffic insight is outside of a predefined range in values from the expected vehicle and/or traffic insight.

7. The communication device of claim 1, wherein confirmation of expected vehicle and/or traffic insight is wherein extracted key current vehicle and/or traffic insight is within a predefined range in values from the expected vehicle and/or traffic insight.

8. The communication device of claim 1, wherein the communication device transmits the smart message when extracted key current vehicle and/or traffic insight is a departure from expected vehicle and/or traffic insight.

9. A system for providing road conditions and monitoring congestion, comprising:

at least one communication device, wherein the communication device further comprises;

a memory; and

a processor configured by the memory to perform the steps of;

extracting key current vehicle and/or traffic insight;

determining if the extracted key current vehicle and/or traffic insight represents a departure from expected vehicle and/or traffic insight;

if the extracted key current vehicle and/or traffic insight is a departure from expected vehicle and/or traffic insight, using the key current vehicle and/or traffic insight to create a smart message, wherein the smart message contains the extracted key current vehicle and/or traffic insight; and

if the extracted key current vehicle and/or traffic insight is a confirmation of expected vehicle and/or traffic insight, creating a confirmation message that does not contain the extracted key current vehicle and/or traffic insight, yet confirms similarity between the extracted key current vehicle and/or traffic insight and the expected vehicle and/or traffic insight; and

a server for communicating with the communication device to receive the smart message and/or the confirmation message.

10. The system of claim 9, wherein the server aggregates traffic conditions and/or road conditions from multiple communication devices, including the at least one communication device.

11. The system of claim 9, wherein the server transmits alerts regarding the aggregated traffic conditions and/or road conditions to at least one of the multiple communication devices.

12. The system of claim 9, wherein the communication device is physically connected to a vehicle, but not electronically connected to the vehicle.

13. The system of claim 9, wherein the communication device is in communication with a vehicle through use of an on board diagnostics (OBD) or OBDII vehicle connection.

14. The system of claim 9, wherein the expected vehicle and/or traffic insight is previously extracted key current vehicle and/or traffic insight from the current vehicle.

15. The system of claim 9, wherein the expected vehicle and/or traffic insight is prior extracted key vehicle and/or traffic insight from other vehicles that were driving on a path that is the same as a path currently being driven by the current vehicle.

16. The system of claim 9, wherein a departure from expected vehicle and/or traffic insight is wherein extracted key current vehicle and/or traffic insight is outside of a predefined range in values from the expected vehicle and/or traffic insight.

17. The system of claim 9, wherein confirmation of expected vehicle and/or traffic insight is wherein extracted key current vehicle and/or traffic insight is within a predefined range in values from the expected vehicle and/or traffic insight.

18. The system of claim 9, wherein the communication device transmits the smart message when extracted key current vehicle and/or traffic insight is a departure from expected vehicle and/or traffic insight.
