Abstract

A method and apparatus for providing timely and efficient notification of vehicle parking space availability and locations of vehicle parking spaces to motorists or other network users. Local detector devices sense the presence or absence of a vehicle in a particular parking space and communicate space identification and status information to a computer network. The parking space status information is integrated with electronic street maps of the area where the relevant spaces are located. Integrated maps containing space status identifiers are communicated to any number of networks.

Claims

1. A parking space locating system comprising:

at least one vehicle detector disposed proximately to an associated parking space and configured to output an occupied/vacant signal along with an associated space identifier according to whether said vehicle detector detects that a vehicle is present/absent in/from said associated parking space respectively;

a central processor in communication with said at least one vehicle detector via at least one communication link;

wherein said central processor is programmed to receive at least one of said occupied/vacancy signals along with said associated space identifiers and maintain an updated database of said occupied/vacant signals along with associated space identifiers,

wherein said central processor integrates said database with geographical map data including a geographical area of said parking space(s) and generates an electronic street map which is capable of being displayed on a standard computer device screen as a graphical map, said graphical map having sufficient detail to distinguish individual parking spaces, wherein said occupied/vacant signal is indicated at a corresponding location on said graphical map;

wherein said central processor is further programmed and configured to quickly communicate updated graphical map data structures including updated occupied/vacant signal indication to a network.

2. The system according to claim 1 wherein said network comprises a publicly accessible network.

3. The system according to claim 1 wherein said network includes an internet.

4. The system according to claim 1 wherein said at least one vehicle detector is disposed in a parking meter.

5. The system according to claim 1 wherein said at least one communication link is an electrical transmission line.

6. The system according to claim 1 wherein said at least one communication link is a microwave link.

7. The system according to claim 1 wherein said at least one communication link is a fiber optic link.

8. The system according to claim 1 wherein said at least one vehicle detector is an ultrasonic metal detector.

9. A method of notifying motorists of vacant parking space locations comprising the steps of:

detecting the presence or absence of a vehicle in at least one identifiable parking space;

generating a signal to represent the presence or absence of the vehicle in said at least one identifiable parking space;

associating said signal with a respective space identifier;

interpreting said signal along with said respective space identifier as space identifier data;

integrating said space identifier data with digital street-map data describing an area including said at least one identifiable parking space to form an active street-map;

wherein said active street-map is capable of being interpreted by standard computer systems for displaying geographical indicators of parking space status at space locations on an electronic street map; and

communicating said active street-map to a network.

10. The method according to claim 9 further comprising the steps of:

communicating said active street map to a mobile-accessible network;

determining a user'"'"'s location using GPS information;

displaying an active-street map of an area including the user'"'"'s position.

11. The method according to claim 9 further comprising the steps of:

periodically updating said active street-map by repeating said step of interpreting said signal along with said respective space identifier as space identifier data; and

repeating said step of integrating said space identifier data with digital street-map data describing an area including said at least one identifiable parking space to form an active street-map.
