Intelligent parking refers to the comprehensive application of wireless communication technology, mobile terminal technology, GPS positioning technology, GIS technology and other technologies to the collection, management, query, booking and navigation services for urban parking spaces, realizing real-time update of parking space resources, query, booking and navigation services integration, maximizing the utilization rate of parking resources, maximizing the profit of the parking lots and optimizing the parking services for the car owners[ 1]. 1].

With the development of "Internet+Parking", Smart Parking[2] realizes parking intelligence, management visualization and operation efficiency by mastering parking big data and relying on the advantages of high-frequency and rigid demand, which can provide owners with e-payment, parking query, parking booking, parking navigation, and peripheral information pushing. The value of the experience[3-4] . And the use of Internet technology and big data, cloud computing to create intelligent parking with many advantages, become a rapid solution to this problem of a feasible program, will bring changes to the entire city parking and travel[5-6] .

At present, smart parking mainly includes the main functions of space guidance, parking lot management, reverse parking search, etc. Some smart parking lots have also added a special vehicle management function, which provides exclusive rights for special vehicles by using technical means such as space sensing, video recognition, and smart card reading, and automatically guides them into exclusive parking spaces[7].
