Modern cities have a lot of trouble finding parking spaces because more people are moving to cities and buying cars. Drivers often spend a lot of time looking for open parking spots, which makes traffic worse, uses more gas, and pollutes the environment. Traditional parking management systems depend on people to keep an eye on things and don't have real-time information about availability. This paper suggests a Smart Parking System with Real-Time Slot Detection that uses web-based technologies and cloud databases to make parking management easier. The proposed system lets users find open parking spaces, book them, and pay for them online all in one place. Finding parking spots in real time makes better use of space and makes things easier for users. The system also uses map services to track locations and help drivers find parking spots nearby. The suggested solution cuts down on traffic jams, saves time and gas, and gives a scalable and effective way to manage parking.
