Background:
The Toronto Parking Authority operates over 17,500 parking spots across Toronto. Approximately, 10,000 of these spaces are by 2,000 ticket meters and the additional 7,500 by single space meters. Currently, a customer either purchases a ticket from the machine and places it on the cars dashboard or inserts coins into a single spot meter. Employees have to walk weekly to collect money from these 9,500 locations. Additionally, the Toronto Police Service offers parking enforcement via dispatched personnel who randomly select areas to monitor. These personnel need to check tickets or parking meters manually and issue tickets as needed. In order to minimize the number of locations to collect money, the Toronto Parking Authority wants to develop an online platform to process payment for select spaces where single parking meters are currently used. The spaces will be numbered and the registered customer can select the space number from their device online to initiate payment. Additionally, parking enforcement will have a separate login into the application which will allow them to see whether an occupied space has been paid for or manage the parking locations.
