A Reservation-based Smart Parking System for Urban Areas

Parking a car has become a matter of great concern in the modern world. Searching for parking spaces is a major reason for traffic jams and environmental contamination. This problem is becoming more prevalent throughout the world. A system with the help of the Internet of Things (IoT) consisting of sensors, processing capability, and software that connects and shares data through the Internet can be developed to solve parking problems. So, we designed a smart parking system by connecting the parking place with a data server and apps over the internet. The parking space status is updated regularly on the server, and the mobile application can read the parking slot status and request a slot. There are two kinds of slots. One is for instant parking and one is for reservation. Users need to pay a specific amount of money in case of pre-booking reservation. Pay-as-you-go for instant parking has been incorporated. Users can recharge their online wallets from mobile banking options. For the anti-theft purpose, we offered an alert and notification feature. Latency tests of different components are measured. Their averages are 5.24s for parking data update, 3.98s for unparking data update, 6.7s for OTP matching and gate open. 3.64s for anti-theft notification and 5.21s for alarm triggering. Quantitative evaluation and black box tests are done to measure the efficiency of the system. By conducting a quantitative evaluation, we got an accuracy of 96.67%.
