Smart service relying on Internet of Things technology in parking systems

In this paper, a smart parking system formed by the integration of smart mobile device applications and Internet of Things (IoT) technology is proposed. The system is able to guide users through the process of searching for a car park until they successfully park the vehicle in a parking lot. The features of the system can be divided into four parts: recommendation and reservation, outdoor navigation to the car park, parking lot detection, and car park indoor navigation. An algorithm is designed to compute the recommendation priority of car parks based on adjustable, given conditions. Outdoor navigation provides a dynamic guide to the user during the trip to the car park. The iBeacon is implemented in indoor navigation to locate the position of users. The RSSI value of the iBeacon is filtered through an algorithm to provide an accurate result. The performance of the iBeacon in a different set-up condition is also evaluated. A field test is performed to acquire data and investigate the operational feasibility of the proposed system.
