Scarcity of physical space has become a fact of life in our crowded modern society. As a result, it has become important to maximize usage of physical space resources in situations involving everything from airplane seating and cargo space to hospital bed availability. One area where a scarcity of physical space has become a challenge relates to parking. For example, for individuals who drive their own vehicles as transportation, finding available parking spaces may be a major inconvenience if their destinations lack ample parking. To make matters worse, if a destination is a workplace at which the individuals must recurrently park in order to go to work, this inconvenience may not only aggravate the individuals, but may also become a major source of lost productivity as workers spend time searching for available parking spaces rather than performing productive work.
At the same time, providing excess parking spaces may be a poor use of limited resources. Particularly in expensive geographical areas where real estate is at a premium, providing more parking spaces than is necessary may be equally or more wasteful, from a fiscal point of view, than the lost productivity and/or ill will that may result from forcing drivers to spend significant effort searching for parking spaces.
The accompanying drawings illustrate various embodiments and are a part of the specification. The illustrated embodiments are merely examples and do not limit the scope of the disclosure. Throughout the drawings, identical or similar reference numbers designate identical or similar elements.
Systems and methods for managing and tracking space availability are described herein. For example, as will be described in more detail below, physical spaces may be managed and/or tracked by monitoring whether the spaces are available, indicating the availability of the spaces to various parties in a variety of ways, and/or otherwise managing and tracking the space availability in any manner as may serve a particular implementation. Examples illustrating systems and methods disclosed herein will focus on managing and tracking parking space availability. However, it will be understood that disclosed systems and methods for managing and tracking space availability may be applied to a variety of scenarios in which any type of physical space may be scarce and/or managed such that people wanting to use the resource associated with the physical space would benefit from the disclosed systems and methods. For example, along with physical spaces associated with parking (i.e., parking spaces), systems and methods disclosed herein may be similarly applied to other resource allocation situations involving spaces associated with seating assignments (e.g., airplane seating, train seating, bus seating, restaurant seating, auditorium or theater seating, etc.), workspaces (e.g., office spaces, cubicle spaces, desk spaces, computer availability, etc.), caretaking spaces (e.g., beds, rooms, or other resources at a hospital, assisted living center, or the like), living spaces (e.g., hostel beds, hotel rooms, etc.), object stowing and/or storage (e.g., cargo stowing in an airplane, cargo tracking, storage unit assignments, etc.), and/or any other resources (e.g., physical spaces) that may be allocated or assigned in a particular implementation.
In an exemplary resource allocation scenario involving parking spaces specifically, a parking facilitation system may include a plurality of parking space devices disposed at a plurality of different parking spaces within a parking area, and a parking management system communicatively coupled to each parking space device in the plurality of parking space devices. The parking space devices and parking management system may interoperate with one another, as well as, in certain examples, with one or more parking facilitation devices to monitor and indicate parking space availability to facilitate the task of locating available parking spaces for drivers.
To this end, each parking space device in the plurality of parking space devices included within the exemplary parking facilitation system may respectively include one or more components for monitoring, indicating, and/or otherwise managing and/or tracking parking space availability. For instance, each parking space device may respectively include a processor, a vehicle presence detector communicatively coupled to the processor, a parking availability indicator communicatively coupled to the processor, a communication interface by way of which the processor is communicatively coupled with the parking management system, and/or any other components as may serve a particular implementation.
When directed by the processor, the vehicle presence detector may determine whether any vehicle is parked in a parking space at which the parking space device is disposed. Similarly, when directed by the processor based on the determination (by the vehicle presence detector) of whether any vehicle is parked in the parking space, the parking availability indicator may visually indicate an availability status of the parking space.
In some examples, each parking space device (or, if the parking space devices are not implemented as integrated units, at least each parking availability indicator) may be positioned, with respect to a particular parking space with which it is associated, at a height greater than a height of any vehicle that the parking space is configured to accommodate. For example, if the parking space is included within a parking garage, the parking space device (or at least the parking availability indicator) may be attached above the parking space to a ceiling or structural element of the parking garage (e.g., attached directly to the ceiling or attached to a structure suspended from the ceiling). In other examples, the parking space device may be attached to a tall structure (e.g., a pole or wall that rises above the height of vehicles for which the parking space is configured) or otherwise suspended above the parking space. In this way, the parking availability indicator may be concurrently visible, with other parking availability indicators of other parking space devices in the plurality of parking space devices, from various locations within the parking area at which drivers attempting to locate available parking spaces are to be located. For example, a driver located at the end of a row of parking spaces may be able to look down the row and see parking availability indicators associated with each parking space on the row regardless of whether vehicles are or are not presently parked in the parking spaces.
As mentioned above, each of the parking space devices included in the parking facilitation system may be communicatively coupled to a parking management system that is also included in the parking facilitation system. The parking management system may be configured to control operation of the plurality of parking space devices. Additionally, the parking management system may exchange, with the plurality of parking space devices, data representative of the availability statuses of the different parking spaces at which the plurality of parking space devices is disposed.
Parking facilitation systems and methods described herein may provide various benefits to drivers attempting to locate available parking spaces, as well as to those who provide (e.g., design, pay for, administer, etc.) parking facilities for those drivers. For example, as drivers are searching for an available parking space, the drivers may be able to quickly and conveniently determine whether a particular parking area (e.g., a floor of a parking garage, a row of parking spaces, etc.) has any available parking spaces and where those parking spaces are located. Because parking availability indicators may be positioned in conspicuous locations at heights greater than the height of vehicles that might be parked in the parking area, drivers may see, at a glance, what the availability status is for each of the parking spaces in the parking area regardless of whether vehicles are parked in the some or all of the parking spaces.
This ability to determine the availability statuses of all the parking spaces at a glance may provide significant convenience to drivers compared to conventional approaches that drivers have used to determine parking space availability. For example, while it may be easy for a driver positioned directly in front of a particular parking space to see whether the parking space is currently occupied, it may be more difficult to determine, from a location at the end of a row of parking spaces, for example, whether any parking space in the row is available. As a result, drivers may drive through parking areas (e.g., rows of parking spaces, floors of parking garages, etc.) that appear to be full to double check that there is not an available parking space that could be used (e.g., a parking space whose availability is obscured from a viewpoint at the end of the row or from a particular place in the parking garage).
Additionally, even if a driver locates a parking space that is not occupied by a vehicle, using a conventional approach, it may be difficult for the driver to determine if the unoccupied parking space is actually an available parking space in which the driver is allowed to park. For example, the unoccupied parking space may be a reserved parking space (e.g., a handicap parking space, a special-use parking space permanently reserved for a certain person or category of people, a general-use parking space that has already been reserved by someone else using a parking pre-reservation system, etc.), a parking space designated for a different type of vehicle, a restricted parking space, or the like. Accordingly, by relying on the parking availability indicators provided by the parking facilitation systems described herein, drivers may not only find more unoccupied parking spaces more quickly and conveniently, but may also more easily and quickly identify which of those unoccupied parking space are available parking spaces that the drivers may use.
Along with these benefits provided at the parking area by way of conspicuously located parking availability indicators, drivers may also benefit from parking facilitation devices that are in communication with the parking facilitation system that is monitoring the parking space availability. For example, as will be described in more detail below, before even entering a parking facility, a driver may access information (e.g., from a mobile device application, from a display sign posted outside the parking area, etc.) indicative of whether parking spaces are available within the parking facility, where within the parking facility the available parking spaces are to be found, and so forth. In some examples, the parking facilitation system may even recommend a specific parking area and/or parking space to the driver by way of these parking facilitation devices and/or may allow the driver to reserve a specific parking space ahead of time.
In addition to benefiting drivers attempting to locate available parking spaces, parking facilitation systems and methods described herein may benefit administrators, companies, venues, and other entities that provide parking facilities. For example, by providing efficient and convenient ways for drivers to find available parking spaces, these entities may improve the morale of their respective patrons (e.g., employees, people attending an event, etc.) while freeing up the patrons to spend their time more productively. In the case of companies who provide parking facilities to employees, this may translate into significant increases in employee productivity without having to increase a number of parking spaces provided, which may not be possible (or may be prohibitively expensive) in certain geographies. Additionally, parking facilitation systems described herein may provide valuable information to parking facility providers regarding current parking space usage patterns. This information may enable the parking facility providers to make beneficial (e.g., cost effective) decisions in relation to how parking is to be administered.
Various embodiments will now be described in more detail with reference to the figures. The disclosed systems and methods may provide one or more of the benefits mentioned above and/or various additional and/or alternative benefits that will be made apparent herein.
It will be recognized that although distinct and separate components for processor 104, vehicle presence detector 106, and parking availability indicator 108 are shown in
In some examples, each parking space device 102 may be implemented as an integrated unit. That is, processor 104, vehicle presence detector 106, parking availability indicator 108, and/or any other components of the parking space device 102 (e.g., including components making up a communication interface and the like) may be implemented within a single enclosure. For example, as will be described in more detail below, each parking space device unit in a plurality of parking space devices 102 may include a processor, a vehicle presence detector, a parking availability indicator, and other suitable components integrated into a single enclosure that is configured to be mounted above a particular parking space.
In other examples, the components of a particular parking space device 102 may be distributed (i.e., not all integrated into a single enclosure unit). For example, a vehicle presence detector of a particular parking space device 102 may be located on the ground (e.g., embedded in concrete of a parking space, attached to a curb adjacent to a parking space, etc.) while a parking availability indicator of the parking space device may be separate from the vehicle presence detector and mounted above the parking space device. The processor for this type of distributed parking space device may be in either of the locations of the vehicle presence detector and the parking availability indicator, distributed across both locations, or in yet another location.
Processor 104, vehicle presence detector 106, parking availability indicator 108, and the communication interface of a particular parking space device 102 (e.g., representative of any of parking space devices 102-1 through 102-N) will now be described in more detail.
Processor 104 may include any microprocessor or other type of processing unit, as well as any custom computer chip or other suitable implementation of computer logic. While not explicitly shown in
Vehicle presence detector 106 may be communicatively coupled to processor 104 and may be configured to determine (e.g., when directed by processor 104) whether any vehicle is parked in a parking space at which the parking space device is disposed. Vehicle presence detector 106 may include any type of sensing or detection technology and may operate in any manner as may serve a particular implementation. For example, in embodiments where the parking space device 102 is implemented as an integrated unit suspended above the parking space, vehicle presence detector 106 may include depth detection technology configured to determine, based on the depth of a surface detected to be immediately below where parking space device 102 is located, whether a vehicle is occupying the parking space. Such depth detection may be based on acoustic depth detection technologies such as ultrasound technology, on laser or other electromagnetic radiation depth detection technologies involving visible light or electromagnetic radiation at other suitable frequencies (e.g., infrared frequencies, microwave frequencies, etc.), or other suitable depth detection technologies. Similarly, vehicle presence detector 106 may be implemented as a camera or other imaging device configured to capture images (e.g., still photos, video images, etc.) that may be analyzed (e.g., by processor 104) to detect whether a vehicle occupies the parking space.
As another example (e.g., for embodiments where the parking space device 102 is in a distributed, rather than an integrated, configuration), vehicle presence detector 106 may operate using other suitable technologies besides depth detection technologies. For instance, vehicle presence detector 106 may include a magnetic sensor associated with the parking space or with a curb adjacent to the parking space, a sensor (e.g., an inductive loop sensor, a pressure sensor, etc.) built into the concrete of the parking space, or the like.
Parking availability indicator 108 may also be communicatively coupled to processor 104 and may be configured to visually indicate (e.g., when directed by processor 104) an availability status of the parking space. For example, the availability status may be determined (e.g., by processor 104) based on a determination by vehicle presence detector 106 whether any vehicle is parked in the parking space, as well as by other information (e.g., parking availability information that processor 104 receives from parking management system 110 related to a reservation status or other special status of the parking space).
Regardless of whether the parking space device 102 is implemented in an integrated configuration within a single consolidated enclosure, or in a distributed configuration, parking availability indicator 108 may be positioned at a height greater than a height of any vehicle that the parking space is configured to accommodate. In this way, parking availability indicator 108 may be concurrently visible, with other parking availability indicators of other parking space devices 102 in the plurality of parking space devices 102, from various locations within the parking area at which drivers attempting to locate available parking spaces are to be located. For example, parking availability indicator 108 may be conspicuously located so as to be visible, regardless of whether a vehicle is occupying the parking space, from various locations within the parking area including, for example, at the end of a row of parking spaces, at one end of a particular level of a parking garage, and so forth. As such, drivers attempting to locate available parking spaces may easily see whether the parking space is available, along with the other parking spaces around the parking space, at a glance without having to slowly drive around each level of the parking garage and/or down each row of parking spaces.
Along with processor 104, vehicle presence detector 106, and parking availability indicator 108, the parking space device 102 may further include other components not explicitly illustrated in
As mentioned above, each of the parking space devices 102 in the plurality of parking space devices 102 may be communicatively coupled to a parking management system 110. Parking management system 110 may include any suitable computing technology (e.g., hardware, software, logic, communication interfaces, etc.) that is configured to control operation of parking space devices 102 and to exchange, with parking space devices 102, data representative of the availability statuses of the parking spaces at which parking space devices 102 are disposed. Parking management system 110 may perform any suitable operations to help system 100 operate in any of the ways described herein. Specific implementations and uses of parking management system 110 will be described in more detail below.
In operation, each parking space device 102 within system 100 may detect vehicle presence and indicate parking space availability in any manner as may serve a particular implementation. For example, a respective vehicle presence detector 106 in a particular parking space device 102 may be configured to determine whether any vehicle is parked in a parking space associated with the parking space device 102 by: 1) directing a pulse toward the parking space at a first time; 2) detecting a reflection of the pulse from a first reflection object at a second time subsequent to the first time; 3) determining, based on a known travel speed of the pulse and a difference between the first and second times, a first distance from the vehicle presence detector to the first reflection object; and 4) determining whether a vehicle is present based on a predetermined distance from the vehicle presence detector 106 to a second reflection object from which pulses reflect when no vehicle is parked in the parking space (e.g., the pavement of the parking space itself). For instance, the vehicle presence detector 106 may determine that no vehicle is parked in the parking space if the first distance is within a predetermined threshold of the predetermined distance (e.g., the distance to the pavement), and that a vehicle is parked in the parking space if the first distance is not within the predetermined threshold of the predetermined distance.
To illustrate,
As illustrated, parking space device 102 may be suspended above a parking space 202 to allow parking space device 102 to determine whether a vehicle is present in parking space 202, as well as to conspicuously indicate (e.g., so as to be visible from various locations around a parking area in which parking space 202 is included) an availability status of parking space 202. These operations may be performed in any suitable way.
For example, a predetermined distance from parking space device 102 (e.g., from the vehicle presence detector 106 within parking space device 102 in particular) to the pavement of parking space 202, which is known to be the reflection object from which pulses will reflect when no vehicle is parked in parking space 202, may be predetermined (e.g., as part of a calibration process that parking space device 102 is put through periodically and/or when the device is initially set up). Accordingly,
As shown in
Based on the predetermined distance from parking space device 102 to the pavement (e.g., which may have been determined during a calibration procedure or the like, as described above), parking space device may now determine whether there is a vehicle present in parking space 202. Specifically, parking space device 102 may determine that no vehicle is parked in parking space 202 because distance 208 is within a predetermined threshold 210 of the predetermined distance. For example, predetermined threshold 210 may be large enough to account for a margin of error in the time of flight calculation and/or to account for minor changes to the height at which pulse 204-A will reflect (e.g., to account for a piece of litter or the like that could be left in parking space 202 and reflect pulse 204-A rather than the pavement to which the predetermined distance was specifically calibrated). At the same time, predetermined threshold 210 may be large enough that parking space 202 will not be detected to be unoccupied even if another object smaller than a typical vehicle but large enough to effectively occupy parking space 202 (e.g., such as a motorcycle, a shopping cart, etc.) is present.
In contrast, as shown in
While the examples in
While
Along with illustrating how vehicle presence is detected by the vehicle presence detector 106 included within parking space device 102,
Parking availability indicator 108 may make this indication in any suitable way. For example, parking availability indicator 108 may shine a light if parking space 202 is available and abstain from shining the light if parking space 202 is unavailable (or vice versa). As another example, parking availability indicator 108 may use colors to indicate different availability statuses. For instance, parking availability indicator 108 may shine a green light in scenarios such as illustrated in
As described above, it may be desirable for parking availability indicator 108 to be located conspicuously so as to be visible to drivers located at various locations throughout a parking area, and not just from a location directly in front of parking space 202. For example, such conspicuousness in parking availability indicator placement may facilitate drivers in locating available parking by allowing them to quickly drive past unavailable parking areas based on the indications from the parking space devices rather than having to search the parking areas manually in hopes of locating an available parking space. To this end, parking availability indicator 108 may be conspicuously positioned in any suitable way. For example, parking availability indicator 108 may be positioned at a height greater than the height of any vehicle that parking space 202 is configured to accommodate by being attached above parking space 202 to a ceiling or structural element of a parking garage within which the parking space is contained. It will be understood that parking availability indicator 108 may be attached to the ceiling or structural element by being attached directly to these structures, by being suspended from these structures, or by being attached to or suspended from other constructions (e.g., cables, pipes, etc.) that are attached to or suspended from these structures in any way as may serve a particular implementation. Additionally, in other examples, parking availability indicator 108 may be implemented in parking areas that are not parking garages (e.g., street parking, outdoor parking lots, etc.). In these and/or other examples, parking availability indicator 108 may be attached to or suspended from a pole, a nearby building, or the like.
To illustrate one example of conspicuous placement of parking availability indicators included within respective parking space devices 102,
Accordingly, a driver attempting to locate a parking space may glance down a row and see, for example, a lineup of exclusively red-colored parking availability indicators. This driver may thus continue searching on the next row, confident that there is not an available parking space he or she is missing without having to have driven down the row. Conversely, in another example, the driver may glance down the row to find mostly red-colored parking availability indicators but also one green parking availability indicators at the end of the row (e.g., associated with a parking space such as parking space 302-5). In this case, the driver can take advantage of the available parking space even though he or she might not have otherwise taken time to drive down the row and discover it. Additionally, the parking availability indicators may provide a convenience of indicating not only whether parking spaces are unoccupied, but, more particularly, whether the parking spaces are actually available for use by particular drivers. For example, parking availability indicators indicating that certain parking spaces are for handicap use only may allow a driver who is not able to use handicap parking spaces to quickly pass by these parking spaces even if they are unoccupied and may otherwise appear to be available from the location of the driver.
As mentioned above, data representative of availability statuses (e.g., which may be at least partially based on determinations of whether parking spaces are unoccupied by vehicles) may be exchanged within system 100 between parking space devices 102 and parking management system 110. The data being exchanged may include data representative of special characteristics associated with particular parking spaces within the plurality of different parking spaces. For example, the special characteristics may be any of the characteristics described herein such as that a parking space is reserved, disabled, only for special use (e.g., compact car use, handicap use, etc.), or the like. The data representative of the special characteristics may be transmitted by parking management system 110 and received by the plurality of parking space devices 102. As such, the respective parking availability indicator included within each parking space device 102 may be configured to visually indicate the availability status of the respective parking space based on both the determination of whether any vehicle is parked in the parking space (i.e., as detected by the respective vehicle presence detector 106), and the data representative of the special characteristics (i.e., the data transmitted by parking management system 110).
While parking area 300 is only shown to include five parking spaces 302, it will be understood that systems and methods for managing and tracking parking space availability may be applied to many parking areas each including many parking spaces. For instance, in certain examples, systems and methods for managing and tracking parking space availability may be used to facilitate parking across garages and lots including hundreds or thousands of parking spaces distributed within many distinct parking areas.
Each parking space 404 may include or be associated with exactly one parking space device 102 so that parking spaces 404 and parking space devices 102 have a one-to-one relationship. In other examples, one parking space device 102 may be configured to cover multiple parking spaces 404 (e.g., multiple adjacent parking spaces). In still other examples, multiple parking space devices 102 may be used to cover each parking space 404. For instance, by associating more than one parking space device 102 with a single parking space 404, the availability status of the parking space 404 may be determined with more accuracy. Specifically, if one parking space device 102 is located above the center of a parking space 404 while other parking space devices 102 are located at the sides of the parking space, system 100 may be able to not only detect when a vehicle is properly parked in the center of the parking space 404 (e.g., based on a detection by the center parking space device 102), but also when the vehicle is improperly parked across two or more parking spaces 404 (e.g., based on a detection by the parking space devices 102 on the sides of the parking space).
As used herein, a “parking area” may refer to any area that includes a plurality of parking spaces that are each located such that parking availability indicators associated with the parking spaces may be visible from various locations within and around the area. For example, in different examples, each row 402 in
Whether or not parking spaces are located in the same parking area in terms of parking availability indicator visibility, interference between different parking space devices 102 that are near one another may arise in certain implementations. For example, if vehicle presence detectors are employed that operate based on transmitting pulses and receiving reflections (e.g., sound-based pulses and reflections such as are transmitted and received by ultrasound-based depth detection technology), interference in which one vehicle presence detector receives a reflection from a pulse transmitted by a different vehicle presence detector at an unknown time may produce unpredictable and erroneous results.
For example,
In
Within a particular potential interface area 506, parking space devices 504 may be near enough to one another to interfere with one another. For example, all of the parking space devices 504 included within potential interference area 506-2 may be near enough to parking space device 504-2 to potentially interfere when parking space device 504-2 attempts to detect whether a vehicle is present in parking space 502-2. In an example employing ultrasound technology to perform vehicle presence detection, for instance, parking space device 504-2 may be near enough to each of the parking space devices 504 included within potential interference area 506-2 to detect (e.g., receive, “hear,” etc.) ultrasound pulses transmitted by these parking space devices 504 (i.e., transmitted for the purpose of detecting vehicles within their own respective parking spaces 502). Additionally, other parking space devices 504 such as parking space devices 504-3 and 504-4 that are technically outside the radius of potential interference area 506-2 but are very near to it, may also pose a potential interference risk and may thus be treated the same as if they were included within potential interference area 506-2. Conversely, various other parking space devices 504 such as parking space device 504-5 may be far enough outside of potential interference area 506-2 so as not to pose a potential interference risk with parking space device 504-2.
A parking facilitation system such as system 100 may avoid potential or detected interference issues problems in any manner as may serve a particular implementation. For example, parking space devices 504 may all be included within a parking facilitation system along with a parking management system (e.g., such as parking management system 110 described above) communicatively coupled with, and configured to manage, all of parking space devices 504. The parking management system may control the operation of each respective parking space device so as to avoid interference. To use parking space device 504-2 as an example, the parking management system may control the operation of parking space device 504-2 by synchronizing a local time maintained by parking space device 504-2 with a master time maintained by the parking management system. The parking management system may also identify an additional parking space device in the plurality of parking space devices that is within a radius of potential interference from the parking space device (e.g., within potential interference area 506-2 or very near to it). For example, the parking management system may identify that parking space device 504-3 is within the radius of potential interference. As a result, the parking management system may direct parking space device 504-2 to perform the determination of whether any vehicle is parked in parking space 502-2 during a first time slot within a plurality of time slots associated with the master time, while directing parking space device 504-3 to perform a determination of whether any vehicle is parked in parking space 502-3 during a second time slot within the plurality of time slots. Specifically, the second time slot may be distinct from, and not overlapping with, the first time slot such that the risk of interference between parking space devices 504-2 and 504-3 is reduced or eliminated due to a separation in time when they each operate.
Additional time slots within the plurality of time slots may thus be assigned to each of the other parking space devices 504 included within potential interference area 506-2, as well as to parking space devices 504 that are very close to potential interference area (e.g., parking space device 504-4), to likewise ensure that these parking space devices 504 do not interfere with vehicle presence detection performed by parking space device 504-2. However, for parking space devices 504 that do not pose an interference risk with parking space device 504-2 (e.g., such as parking space devices 504-1, 504-5, and other parking space devices far outside the radius of potential interference represented by potential interference area 506-2), a time slot may be assigned that is not distinct from and/or that does overlap with the first time slot assigned to parking space device 504-2.
More specifically, the parking management system may further control the operation of parking space device 504-2 by identifying an additional parking space device that is outside the radius of potential interference from parking space device 504-2 (e.g., parking space device 504-5). The parking management system may then direct the additional parking space device to perform a determination of whether any vehicle is parked in its respective parking space (e.g., parking space 502-5) during the first time slot.
Along with separating vehicle presence detection operations by time as described above (i.e., assigning different time slots to neighboring parking space devices 504 to avoid interference between them), other methods of separating vehicle presence detection operations or otherwise minimizing interference potential may also be employed as may serve a particular implementation. For example, instead of a time separation between parking space devices 504, a frequency separation may be employed where neighboring parking space devices 504 are each assigned unique frequencies at which to transmit and receive pulses.
In theory, most or all vehicle presence detection interference of the type described above may be eliminated by preplanning and selectively assigning different time slots or pulse frequencies to each parking space device 504 operating in a particular parking area. However, in practice, issues may arise that still cause parking space devices 504 to become unsynchronized and/or to otherwise unexpectedly interfere with one another. Additionally, it may be desirable for a parking facilitation system to eliminate interference without strategic preplanning on the part of operators administering the parking facilitation system.
As a result, artificial intelligence, machine learning, and other such techniques may be employed to detect, identify, and handle interference issues in an automated fashion that does not require human intervention. For example, a machine learning algorithm may identify an interference issue when an unexpected behavior or result is observed. Potential interference issues may be revealed, for instance, by an observation that a particular vehicle presence detector is toggling too often (i.e., indicating that a vehicle is repeatedly pulling in and pulling out of the associated parking space at a rate or for a duration of time that is unlikely to be occurring in actuality). As another example, potential interference issues may be revealed by an observation that the time of flight of transmitted pulses is too short or too long (i.e., indicating that a vehicle is of a size or shape that it is unlikely to be in actuality).
When such potential interference issues are identified, the parking facilitation system may reassign time slots or frequencies as appropriate to attempt to resolve the interference issues. Specifically, referring again to the example of parking space device 504-2, the parking management system within the parking facilitation system may control the operation of parking space device 504-2 by recognizing (e.g., based on a machine learning algorithm) an anomalous outcome of the determination of whether any vehicle is parked in parking space 502-2 (e.g., an anomalous outcome such as the potential interference issues described above). The parking management system may then direct parking space device 504-2 to perform subsequent determinations of whether any vehicle is parked in parking space 502-2 during a different time slot within the plurality of time slots. For example, a time slot distinct from, and not overlapping with, the first time slot or any other time slots currently assigned to parking space devices 504 within the radius of potential interference may be assigned. Additionally or alternatively, the parking management system may also swap assigned time slots, readjust all the time slots to be further apart or closer together, add new time slots to the plurality of time slots being used, or the like. For example, if ten time slots of one second each are being used (i.e., such that each of ten parking space devices repeatedly determines whether any vehicle is parked in its respective parking space during a one-second period every ten seconds) when the machine learning algorithm recognizes the anomalous outcome, an eleventh time slot may be added such that each of the ten parking space devices begins to perform the determination only once every eleven seconds.
As described and illustrated above in relation to
Mesh network 602 may provide a communication infrastructure by way of which parking space devices 102 may communicate with one another and with gateway device 604. For example, parking space devices 102 may each include a communication interface based on wireless radio technology. However, every parking space device 102 may not have close proximity to gateway device 604, a line of sight with gateway device 604 by way of which radio signals may travel without interference, or the like. Accordingly, it may not be possible for each parking space device 102 to communicate with gateway device 604 directly, especially if there are hundreds of parking space devices 102 in a large, multi-level, concrete parking garage through which wireless signals cannot easily travel. Rather than direct communication, parking space devices 102 may thus communicate by passing messages from device to device (e.g., between devices that are near one another and/or have good line of sight or the like) in a mesh networking fashion.
Gateway 604 may be included within parking management system 110 along with parking management server 606, or, in other examples, may implement parking management system 110 alone or with other components. In some examples, multiple gateway devices 604 (e.g., each associated with a few hundred parking space devices 102, for instance) may be employed to communicate with one another and with parking management server 606 in an exemplary implementation of parking management system 110. Gateway device 604 may facilitate communications between parking space devices 102 and parking management server 606 by receiving, consolidating, and exchanging messages (e.g., including data representative of instructions, availability statuses of parking spaces, etc.) between the parking space devices 102 on mesh network 602 and parking management server 606 over network 608.
Parking management server 606 may similarly be included within or may implement parking management system 110, and may include processing, memory, and storage resources for performing any of the operations described herein. For example, parking management server 606 may include one or more computing devices (e.g., server computers, database storage centers, etc.) for controlling operation of the plurality of parking space devices 102 on mesh network 602 in any of the ways described herein and/or for exchanging data with the parking space devices 102. For example, the exchanged data may be representative of the availability statuses of the different parking spaces at which the plurality of parking space devices 602 is disposed. Parking management server 606 may be communicatively coupled with one or more gateway devices such as gateway device 604 to manage as many parking space devices 102 as may be employed in a particular implementation.
Network 608 may provide data delivery infrastructure between gateway device 604 and parking management server 606. As such, network 608 may include a provider-specific wired or wireless communication network (e.g., a cable or satellite carrier network or a mobile telephone network), the Internet, a wide area network, a content delivery network, and/or any other suitable network or networks, and data may be distributed using any suitable communication technologies included within network 608.
Similarly, network 610 may provide data delivery infrastructure between parking management server 606 and parking facilitation devices such as parking facilitation devices 612, parking facilitation display sign 616, and parking analytics system 620. Like network 608, network 610 may include any provider-specific wired or wireless communication network, the Internet, a wide area network, a content delivery network, and/or any other suitable network or networks, and data may be distributed using any suitable communication technologies included within network 608. In some examples, network 610 may be integrated with network 608, while, in other examples, networks 608 and 610 may be separate and distinct from one another. On either network 608 or 610, data may flow using any communication technologies, devices, media, and protocols as may serve a particular implementation.
Collectively implementing parking management system 110, either or both of gateway device 604 and/or parking management server 606 may operate to manage and control parking space devices 102 in any manner as may serve a particular implementation. For example, as described above, either of these components may store and transmit data representative of parking space availability such as relating to reserved or special parking spaces. As another example, when firmware updates are released for parking space devices 102, parking management server 606 and/or gateway device 604 may systematically load the new firmware onto parking space devices 102 (e.g., in the background as the parking space devices continue to operate), confirm (e.g., via comparing checksums, etc.) that each parking space device 102 has properly received and stored an uncorrupted image of the new firmware, and direct each parking space device 102 to restart using the newly loaded firmware.
In addition to interoperating with gateway device 604 to manage parking space devices 102, parking management server 606 may be further configured to provide data representative of the availability statuses of different parking spaces to one or more parking facilitation devices communicatively coupled to parking management server 606. These parking facilitation devices may be any suitable devices as may serve a particular implementation.
As one example, parking facilitation devices may be implemented by respective mobile devices (e.g., parking facilitation devices 612) associated with drivers attempting to locate the available parking spaces (e.g., users 614). For example, mobile devices may include smart phones, tablet computers, laptop computers, smart watches, car navigation systems, and/or other mobile devices that may be used by drivers or passengers within a vehicle trying a locate an available parking space.
Parking facilitation devices 612 may be configured to present (e.g., to respective users 614) data representative of the availability statuses of the different parking spaces at which parking space devices 102 are disposed. For example, parking facilitation devices 612 may receive the data representative of the availability statuses from parking management server 606 as described above and may present the data in any suitable way.
To illustrate,
In this way, the user may conveniently determine, in real time with minimal wasted time, at which levels and/or sections he or she is mostly likely to find available parking spaces. For example, based on the information presented in
User interface 700 may be navigable by the user (e.g., using the back button and/or other conventional navigation techniques) to further explore the availability statuses of parking spaces in other levels and sections of the parking garage and/or of other parking facilities (e.g., other parking garages, etc.). Additionally, user interface 700 may include additional features such as a reservation feature allowing a user to reserve a particular parking space before arriving at the parking area, a recommendation feature that automatically recommends a particular parking space or parking area (e.g., level, section, etc.) to the user as the user arrives at the garage, a map feature to help the user navigate to and/or within particular parking areas, and/or any other feature as may serve a particular implementation.

In certain examples, the parking availability indicators may be positioned at a height greater than a height of any vehicle that the different parking spaces are configured to accommodate. As such, the parking availability indicators may be concurrently visible from various locations within the parking area at which drivers attempting to locate available parking spaces are to be located. Operation 906 may be performed in any of the ways described herein.
In operation 908, the plurality of parking space devices included within the parking facilitation system may exchange, with the parking management system, data representative of the respective availability statuses of the different parking spaces.
