Abstract
Changes in a road network may be detected and information/data regarding the change may be locally propagated in at least near real time with respect to the detection of the change. A vehicle apparatus onboard a vehicle analyzes sensor data collected as the vehicle traverses at least a portion of a road network. The sensor data is captured by sensors onboard the vehicle. The sensor data is analyzed in at least near real time with respect to the capturing of the sensor data. The vehicle apparatus detects an inconsistency between a result of the analysis of the sensor data and map data stored in the memory. Responsive to the detected inconsistency satisfying a vehicle-to-vehicle criterion, the vehicle apparatus generates a notification message comprising an indication of the detected inconsistency. The vehicles apparatus transmits the notification message via a communication interface using a short or medium range communication protocol.
