Consensus-based monitoring of driving behavior in connected vehicle systems

A computer program product for vehicle traffic behavior monitoring and feedback, the computer program product comprising:

• one or more computer readable storage media;
• and
• program instructions executable by a processor and collectively stored on the one or more computer readable storage media, the program instructions comprising:
• program instructions to collect vehicle sensor data from a set of vehicles operating in a traffic environment, wherein each vehicle transmits vehicle sensor data via a communications network to a processor;
• program instructions to determine whether to analyze the vehicle sensor data by determining whether the set of vehicles includes enough vehicles to form a quorum;
• program instructions to form, responsive to determining that the set of vehicles forms a quorum, a consensus block of aggregate data, wherein the aggregate data comprises individual vehicle sensor data from each vehicle in the set of vehicles, and wherein the processor discards duplicate data and repetitive data from the consensus block;
• program instructions to detect, in the consensus block, a vehicle motion pattern, wherein the vehicle motion pattern deviates from a threshold by greater than a tolerance;
• program instructions to map the vehicle motion pattern to a particular vehicle in the set of vehicles;
• and
• program instructions to generate a feedback response based on the mapping.

A computer system, comprising:

• a processor;
• a computer-readable memory;
• a computer-readable storage device;
• and
• program instructions stored on the storage device for execution by the processor via the memory, the stored program instructions comprising:
• program instructions to collect vehicle sensor data from a set of vehicles operating in a traffic environment, wherein each vehicle transmits vehicle sensor data via a communications network to a processor;
• program instructions to determine whether to analyze the vehicle sensor data by determining whether the set of vehicles includes enough vehicles to form a quorum;
