Using v2x-based in-network message generation, aggregation, distribution and processing protocols to enable road hazard condition warning applications

A method for detecting potentially hazardous road conditions, said method comprising:

• detecting a road condition by sensors on a plurality of vehicles around the road condition where each vehicle detecting the road condition assigns the detected road condition a confidence value;
• transmitting the confidence value of the road condition from each vehicle that detects the road condition to other vehicles;
• aggregating the confidence value in one or more vehicles to generate an aggregated result that identifies the probability that the road condition is occurring;
• and
• causing a vehicle to act on the road condition if the aggregated result exceeds a predetermined threshold.

A system for detecting potentially hazardous road conditions, said system comprising:

• means for detecting a road condition by sensors on a plurality of vehicles around the road condition for each vehicle detecting the road condition assigns the detected road condition a confidence value;
• means for transmitting the confidence value of the road condition from each vehicle that detects the road condition to other vehicles;
• means for aggregating the confidence value in one or more of the plurality of vehicles to generate an aggregated result that identifies the probability that the road condition is occurring;
• and
• means for wirelessly transmitting the aggregated result in a multi-hop manner to vehicles approaching the road condition.
