The Online Car Parking System enables customers/drivers to reserve a parking space. It also allows the customers/drivers to view the parking status at specific location. It was developed because the congestion and collision of the vehicle, so we developed this system. Therefore the project aimed at solving such problems by designing a web based system that will enable the customers/drivers to make a reservation of available parking space. The designed system was implemented using different development tools which include HTML for creating interfaces, CSS for styling wed pages ,JavaScript, and Jquery for dynamism in the web pages and as an input validation tool.XAMMP was used to build the database and PHP used as a server side scripting language to connect the user interfaces to the database.
