Embodiments of the present invention provide a system and method for maintaining a record of parking space usage data for a plurality of parking spaces, using the usage data to compute probability of availability for a given space as a function of time and communicating the resultant probability data along with availability data to an end user who is looking for a parking space in the area. This information can be combined with a user's estimated time of arrival (ETA) to assist the user in selecting a parking spot to drive to. A plurality of spaces can be ranked according to their likelihood of availability at an ETA to the general area or to each of the plurality of spaces.
