Abstract

A system forecasts parking availability for a time in the future based on driver-reported estimations of how long each vehicle in the parking area will stay and on forecasted arrivals. Current conditions in a parking area might misrepresent parking availability at the time when a driver will arrive. When accessing parking, drivers need a data input mechanism to report their expected stays, such as a smart ticket dispenser or parking meter. The data goes through a computer algorithm to forecast parking availability. This forecast can be communicated to remote parking access points.

Claims

1. A method of forecasting parking availability for a parking lot of given capacity comprising the steps of:

a) upon a vehicle entering the parking lot, providing information relating to an estimated length of stay of the vehicle, associating a time of entry with said information, and issuing an identifier to the vehicle that is linked to the parking lot entry;

b) forecasting an additional number of vehicles entering and staying in the parking lot based on a remote checkpoint that identifies the additional numbers of vehicles or historical data of vehicles entering the parking lot;

c) forecasting space availability in the parking lot using the information gathered from the number of vehicles that entered the lot and the forecasted number of vehicles that will enter the lot;

d) providing the projected space availability to vehicles at one or more locations, at least one location remote from the parking lot entry so that alternative action can be taken if no parking availability exists.

2. The method of claim 1, wherein traveling to the parking lot from the remote location requires a significant amount of travel time from the location(s) where drivers must make a decision about parking there.

3. The method of claim 1, wherein historical data based on a number of cars visiting a site being served by the parking lot is used as part of step (b).

4. The method of claim 1, wherein the information of step (a) is gathered from a number of parking lots, and information regarding availability of parking in the number of parking lots is provided.

5. The method of claim 1, wherein the identifier includes a ticket adapted to be dispensed to a vehicle user.

6. The method of claim 1, wherein the historical data includes weather data.

7. The method of claim 1, wherein information about vehicles exiting the lot is used as part of the step (c).

8. A system for projecting parking availability for a parking lot of given capacity comprising:

a) a parking area entry device which is adapted to receive information relating to an estimated length of stay of a vehicle, associate a time of entry with said information, and generate an identifier related to the vehicle that is linked to the parking area entry;

b) a database storing information received from the parking area entry device either historical information of vehicle traffic to the parking lot over time or information from a remote checkpoint which is adapted to receive information relating to a vehicle traveling to the parking lot and an estimated length of stay, or both;

c) computing means for projecting availability of spaces in the parking lot based on database information; and

d) means for communicating the projected parking space availability at least in a location remote from the parking lot.

9. The system of claim 8, wherein the database includes weather data as part of the historical data.

10. The system of claim 8, further comprising a plurality of parking lot entry devices located in a plurality of parking lots.

11. The system of claim 8, wherein the parking lot entry device dispenses a ticket as part of the identifier.

12. The system of claim 8, further comprising a parking lot exit device used to obtain actual time of departure for the space reservation associated with the identifier'"'"'s record, such that the exit data will update the database by the computing means.

13. The system of claim 12, wherein the parking lot exit device includes a manual input device for inputting information regarding entry into the parking area.

14. The system of claim 8, wherein communication of the parking availability occurs on one or more of a road sign, a handheld or desktop electronic device, in-vehicle devices, a wireless or non-wireless communication device, radio, telephone, and printed material.
