Road accident detection and avoidance using blockchain

A system for road accident avoidance receives sensor data from computing devices associated with vehicles traveling on a road. The system communicates the sensor data to a blockchain network as blockchain records. The system determines that the sensor data includes an indication of a road accident. The system determines a location of the road accident from the sensor data. The system communicates, to the blockchain ledger, data that indicates the location of the road accident. The system identifies one or more vehicles within a threshold distance of the road accident that are traveling toward the road accident. The system communicates an alert signal that comprises the location of the road accident to each vehicle. The system determines a routing recommendation for each vehicle based on the location of the vehicle and the location of the road accident. The system communicates the routing recommendation to the vehicle.
