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, wherein the message is received in a single wireless carrier wave;
a processor configured to determine;
that the message is an urgent message or a non-urgent message; and
from the single wireless carrier wave at least one of a speed of the communication node and a distance between the traffic information communication system and the communication node;
a transmitter communicatively coupled to the receiver and configured to rebroadcast the message within a predetermined amount of time after receiving the message, 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/or using a resource block from a first set of resource blocks reserved for non-urgent messages;
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/or using a resource block from a second set of resource blocks reserved for urgent messages; and
the traffic information communication system is implemented in a vehicle traveling along the thoroughfare; 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, wherein at least one of;
the sensor comprises a brake sensor configured to detect emergent braking in the vehicle;
orthe sensor comprises a component sensor configured to detect failure of a particular vehicle component in the vehicle.

7. A method of providing communications regarding traffic conditions, the method comprising:
-
receiving, at a first vehicle traveling along a thoroughfare, a message from a second vehicle relating to traffic conditions along the thoroughfare, wherein the message is received in a single wireless carrier wave; determining that the message is an urgent message or a non-urgent message; determining from the single wireless carrier wave at least one of a speed of the second vehicle and a distance between the first vehicle and the second vehicle; determining that the traffic conditions may affect other vehicles traveling along the thoroughfare; in response to the determination that the traffic conditions may affect 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/or using a resource block from a first set of resource blocks reserved for non-urgent messages; 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 and/or using a resource block from a second set of resource blocks reserved for urgent messages; detecting a trigger by a sensor installed in the first vehicle, wherein the sensor comprises a brake sensor configured to detect emergent braking in the first vehicle or a component sensor configured to detect failure of a particular vehicle component in the first vehicle; and generating and broadcasting a warning message relating to a potential safety threat to other vehicles in response to detecting the trigger. - View Dependent Claims (8, 9, 10, 11, 12)

13. A processor configured to execute computer instructions to cause a system to perform operations for providing communications regarding traffic conditions, the operations comprising:
-
receiving a single carrier signal from a first vehicle; determining from the single carrier signal at least one of a speed of the first vehicle and a distance between the processor and the first vehicle; extracting, from the single carrier signal, a message relating to traffic conditions along a thoroughfare; determining that the message is an urgent message or a non-urgent message; determining that the traffic conditions may affect other vehicles traveling along the thoroughfare; in response to the determination that the traffic conditions may affect 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/or using a resource block from a first set of resource blocks reserved for non-urgent messages; 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 and/or using a resource block from a second set of resource blocks reserved for urgent messages; detecting a trigger by a sensor, wherein the sensor comprises a brake sensor configured to detect emergent braking or a component sensor configured to detect failure of a particular vehicle component; and generating and broadcasting a warning message relating to a potential safety threat to other vehicles in response to detecting the trigger. - View Dependent Claims (14, 15, 16, 17, 18, 19)
