Intelligent car parking systems leverage sensors and data analysis algorithms to optimize parking allocation and provide a seamless parking experience through integration with mobile apps and payments. These systems first emerged in major US cities in the 1920s and work by using cameras and sensors to detect available spots and guide drivers to them while collecting real-time data to predict parking needs. They enable users to reserve spots and pay for parking via mobile apps or payment kiosks. While providing benefits like reduced pollution and parking times, intelligent parking systems also require expensive installation and regular maintenance.
