1. A traffic information communication system comprising:
- a receiver configured to receive a message relating to traffic conditions along a thoroughfare from a communication node;
a processor configured to determine that the message is an urgent message or a non-urgent message;
a transmitter communicatively coupled to the receiver and configured to rebroadcast the message within a predetermined amount of time after receiving the message, wherein the traffic information communication system is implemented in a vehicle traveling along the thoroughfare, wherein;
when the message is a non-urgent message, the transmitter is configured to rebroadcast the message at a default transmission power that indicates the message is a non-urgent message; and
when the message is an urgent message, the transmitter is configured to rebroadcast the message at an initial transmission power that is greater than the default transmission power and that indicates the message is an urgent message; and
a sensor installed in the vehicle and configured to detect a trigger, wherein the transmitter is further configured to generate and broadcast a warning message relating to a potential safety threat to other vehicles in response to detecting the trigger.

8. A method of providing communications regarding traffic conditions, the method comprising:
-
detecting a trigger by a sensor installed in a first vehicle traveling along a thoroughfare; generating and broadcasting a warning message relating to a potential safety threat to other vehicles traveling along the thoroughfare in response to detecting the trigger; receiving, at the first vehicle, a message from a second vehicle relating to traffic conditions along the thoroughfare; determining that the message is an urgent message or a non-urgent message; determining that the traffic conditions may affect the other vehicles traveling along the thoroughfare; and in response to the determination that the traffic conditions may affect the other vehicles traveling along the thoroughfare, rebroadcasting the message within a predetermined amount of time after receiving the message, wherein; when the message is a non-urgent message, the message is rebroadcast at a default transmission power that indicates the message is a non-urgent message; and when the message is an urgent message, the message is rebroadcast at an initial transmission power that is greater than the default transmission power and that indicates the message is an urgent message. - View Dependent Claims (9, 10, 11, 12, 19)

13. A processor configured to execute computer instructions to cause a system to perform operations for providing communications regarding traffic conditions, the operations comprising:
-
detecting a trigger by a sensor installed in a first vehicle traveling along a thoroughfare; generating and broadcasting a warning message relating to a potential safety threat to other vehicles traveling along the thoroughfare in response to detecting the trigger; receiving, at the first vehicle, a message from a second vehicle relating to traffic conditions along the thoroughfare; determining that the message is an urgent message or a non-urgent message; determining that the traffic conditions may affect the other vehicles traveling along the thoroughfare; and in response to the determination that the traffic conditions may affect the other vehicles traveling along the thoroughfare, rebroadcasting the message within a predetermined amount of time after receiving the message, wherein; when the message is a non-urgent message, the message is rebroadcast at a default transmission power that indicates the message is a non-urgent message; and when the message is an urgent message, the message is rebroadcast at an initial transmission power that is greater than the default transmission power and that indicates the message is an urgent message. - View Dependent Claims (14, 15, 16, 17, 20)
