A method and system are disclosed for controlling use of predetermined vehicle parking areas and/or transit in predetermined vehicle circulation areas. The system comprises a control unit in communication with a telephone network and a database, the database storing data including an electronic map of one or more of such areas. When the control unit receives a Short Message Services (SMS) message from a user, via the network, requesting access to one of the areas at a selected time, the message is com-pared to data in the database in order to assess whether or not to comply with the request. If it is determined that the request should be complied with, then the database is updated with an indication of an access reservation. The unit then sends the user an SMS message in response, either confirming the reservation or denying availability of access.
