Patent Images
1. A system for determining the availability of parking spaces including on-street parking spaces, comprising:
- a non-stereoscopic optical detector adapted to scan a plurality of the on-street parking spaces and to produce scan data for the on-street parking spaces scanned;
a processor adapted to receive the scan data from the optical detector and to determine the availability of the on-street parking spaces scanned from the scan data; and
a device adapted to receive parking space availability data from the processor, the device adapted to broadcast information on available ones of the parking spaces to interested persons via AM or FM transmission or to wireless telephone devices.

-
11. A method for determining the availability of parking spaces including on-street parking spaces, comprising:
-
viewing a plurality of on-street parking spaces with a non-stereoscopic video camera to produce one or more images;
processing the one or more images to determine whether an associated on-street parking space is available;
updating a list to reflect the availability of the plurality of the on-street parking spaces in response to processing the one or more images; and
broadcasting a signal indicating the availability of a portion of the plurality of parking spaces to interested persons via AM or FM transmission or to wireless telephone devices. - View Dependent Claims (12, 13)
receiving a telephone request from the motorist for the availability of a selected portion of the plurality of parking spaces; and
wherein the act of transmitting indicates the availability of the selected portion.
