Design of "Blockchain Plus" intelligent parking matching guidance system

The "Blockchain Plus" intelligent parking matching guidance system was designed on the basis of the analysis of the technologies of blockchain, parking space reservations, parking matching guidance, vehicle service navigation. The system consists of application layer, blockchain technical service layer, network layer, and data layer, using blockchain technologies such as aggregation chain architecture based consensus algorithm services, smart contract services, and anti-counterfeiting verification supported by digital DNA, to provide services such as parking space reservation, intelligent matching parking space, vehicle service navigation to optimize parking matching, parking searching, and parking route guidance. The system performance test shows that the average matching time, average parking searching time, average parking index, average parking success rate and other performance data are better than other similar parking service systems. Therefore, this system can offer a proven help to solve the problems including unbalanced supply and demand of parking space in urban area, travel difficulties and so on.
