Abstract

A “smart parking” system and method for an urban environment based on a dynamic resource allocation approach. The system assigns and reserves an optimal resource (parking space) for a discrete user based on the user'"'"'s objective function that combines proximity to destination with parking cost, while also ensuring that the overall parking capacity is efficiently utilized. The solution of each Mixed Integer Linear Program (MILP) is an optimal allocation based on current state information and subject to random events such as new user requests or parking spaces becoming available.

Claims

1. A parking allocation and management system for an urban environment for optimally allocating and reserving parking resources for a discrete user based on a user'"'"'s parking preferences, the system comprising:

a parking resource management center that is adapted to continuously track in real-time a state of occupancy and geographical location of each parking location of a multiplicity of parking locations within the urban environment and to generate state of occupancy data signals and parking resource geographical location data signals;

a driver request processing center that is adapted to continuously receive user requests and user geographical location data and to generate user request data signals and user geographical location data signals; and

a smart parking allocation center that is adapted to receive said state of occupancy data signals, said parking resource geographical location data signals, said user request data signals, and said user geographical location data signals in order to optimally allocate to and reserve parking resources for each discrete user and to dynamically and continuously re-allocate and reserve parking resources until each discrete user has changed the state of occupancy of an allocated and accepted parking resource.

2. The system as recited in claim 1, wherein the driver request processing center includes at least on of:

a processing/communication device for communicating with the user;

a processing/communication device for communicating with the smart parking allocation center;

a database for storing the user'"'"'s real-time geographical positional data;

a database for storing user parking requests;

a database for storing parking offers made to users;

a database for storing user acceptance of parking offers; and

a database for user parking preference data.

3. The system as recited in claim 1, wherein the parking resource management center includes at least one of:

a processing/communication device that is in communication with and capable of transmitting data signals to a plurality of variable-message signs;

a gateway that is adapted to store and maintain local parking information collected from a plurality of occupancy sensors at on-street parking spots;

a gateway that is adapted to store and maintain local parking information collected from a plurality of occupancy sensors at off-street parking spots;

a database for storing real-time geographical positional data on the on-street and off-street parking spots;

a database for storing real-time geographical positional data on vacant on-street and off-street parking spots;

a database for storing real-time geographical positional data on reserved on-street and off-street parking spots; and

a database for storing real-time geographical positional data on occupied on-street and off-street parking spots.

4. The system as recited in claim 1, wherein the smart parking allocation center includes at least one of:

a processing/communication device that is in communication with and capable of transmitting to and receiving data signals from the parking resource management center and the driver requests processing center;

an allocation period timing device;

a database for storing parking resource reservation data; and

a database for storing reservation fee billing data.

5. The system as recited in claim 1 further comprising a communication device that enables a user to communicate with the smart parking allocation center.

6. The system as recited in claim 5, wherein the communication device includes a database for storing user-specified parking requirements or preferences.

7. The system as recited in claim 6, wherein the user-specified parking requirements or preferences include:

an upper bound constraint on an acceptable parking cost; and

an upper bound constraint on an acceptable walking distance between the allocated parking resource and a user'"'"'s final destination.

8. The system as recited in claim 4, wherein the allocation period timing device provides a pre-established period of time during which user requests are received;

parking resources are allocated;

parking resources are reserved; and

unfulfilled user requests are placed in a reserve queue if a parking resource has been allocated and reserved for the discrete user or in a wait queue if no parking resource has been allocated.

9. A method of optimally allocating and reserving parking resources in an urban environment for a discrete user based on a user'"'"'s parking preferences, the method comprising:

receiving a parking request for a parking allocation from at least one user;

continuously receiving geographical positioning data for each of the at least one user;

identifying each of the at least one user'"'"'s corresponding parking preferences;

receiving continuous parking resource data as to a geographical location and a state of occupancy or vacancy of each parking resource within the urban environment;

optimally allocating parking resources to select users during a first allocation period based on given performance metrics;

reserving an allocated parking resource for a select user after said select user has expressed a desired for the allocated parking resource; and

continuing to optimally allocate comparable or better parking resources to the select user during a second and subsequent allocation periods.

10. The method as recited in claim 9, wherein identifying each of the at least one user and corresponding parking preferences further comprising:

preparing, in advance of receiving a parking request, user-specified parking requirements or preferences for each discrete user; and

modifying the user-specified parking requirements or preferences at any time after initial preparation.

11. The method as recited in claim 10, wherein preparing user-specified parking requirements or preferences for each discrete user includes:

providing an upper bound constraint on an acceptable parking cost; and

providing an upper bound constraint on an acceptable walking distance between the allocated parking resource and a user'"'"'s final destination.

12. The method as recited in claim 11 further comprising transmitting a message to the user, prompting the user to amend his/her user-specified parking requirements or preferences after a predetermined number of allocations periods.

13. The method as recited in claim 9 further comprising providing driving directions to the select user to the allocated parking resource.

14. The method as recited in claim 9 further comprising:

dynamically re-allocating a reserved but unoccupied parking resource from a first select user to a second select user during a subsequent allocation period; and

allocating another parking resource to the first select user.

15. The method as recited in claim 9, wherein continuing to optimally allocate comparable or better parking resources to the select user during a second and subsequent allocation periods includes:

offering substitute parking resources to select users during a second and subsequent allocation periods; and

reserving an allocated parking resource for said select user after said select user has expressed a desired for the substitute parking resource.

16. The method as recited in claim 9 further comprising placing each user in a reserve queue if a parking resource has been allocated and reserved for the discrete user or in a wait queue if no parking resource has been allocated during any allocation period.

17. The method as recited in claim 14 wherein optimally allocating parking resources to select users includes immediately allocating a parking resource without placing the user in a queue when:

the parking cost of the parking resource is less than the upper bound constraint on parking cost;

the walking distance to the user'"'"'s final destination is less than the upper bound constraint on an acceptable walking distance; and

the user can occupy the allocated parking resource prior to beginning of the second or subsequent allocation period.
