A method and implementing computer system are provided for enabling management of restricted parking spaces for vehicles. In an example, a sensing system senses the presence of vehicles in predetermined parking spaces and stores that information for subsequent processing. Particular parking restrictions, or limited parking indicia, for given parking spaces are displayed and viewable to vehicle operators. The posted parking restriction indicia are selectively changeable to accommodate various parking demand situations. The displayed limited parking indicia may be changed from one type of limited parking to other types of limited (or unlimited) parking from a remote server location, either selectively by an administrator or in accordance with a stored parking authorization plan or schedule. Vehicles are scanned for proper authorization for predetermined types of parking spaces. Alarms or other notification processes are implemented to provide notification of unauthorized vehicles which are parked in restricted parking spaces.
