The current invention provides a real-time wireless parking enforcement system that utilizes parking occupancy, parking payment data, and wireless mobile platforms to provide real-time, continuous information flow to management and parking enforcement officers (PEO) resulting in improved operational efficiency and increased quantity and fairness of citation issuance.
According to one embodiment of the invention, real-time information flows from the remote parking meter monitoring and payment reporting system, and a plurality of wireless mobile platforms to a central server and archive engine used to collect and archive the collected information. The central server and archive engine component collects, processes, and archives the information provided by the system subcomponents. It also supports reporting, querying and optimization of enforcement workforce by supervisors based on historical information as well as supporting real-time monitoring and direction of the workforce.
Optionally, additional information, such as traffic speeds and vehicle counts, flows into the central server and archive engine as well. In yet another aspect of the invention, the parking occupancy data and parking payment data further includes guidance information to the PEO for a maximization of citation revenue, where the guidance information can includes occupancy levels, demand for parking spaces in a region, or street traffic in surrounding areas of the parking space.
In one aspect, parking enforcement officers (PEO's) access the display and deployment engine from their wireless mobile terminals. The wireless mobile terminals may be further integrated in some manner with a ticket issuance system and touchscreen operation.
According to one embodiment, the real-time wireless parking enforcement system provides real-time information about the state of individual spaces that are being managed by the overall system. Each state change is reported, either by the sensor or by a PEO as soon as the information becomes available along with the time when the state change occurred. States that are reported may include sensor outage, possible departure, possible arrival, definite departure, definite arrival, sensor delay, occupied, vacant, and/or indeterminate.
In a further aspect of the invention, the payment reporting system provides real-time information relating to the payment for parking spaces managed by the system that can include the quantity of payment or payment and expiration times for the corresponding individual spaces that are being managed by the system, where the payment may be provided by a single or multi-space meter, by a server connected to one or more meters, by a pay-by-cell system, or may be entered into the system by the PEO. The information relating to the payment for parking spaces managed by the system can also include the remaining time before the current vehicle parked in the space becomes a violation, and the policy in effect for the vehicle currently parked in the space such as whether the vehicle is claimed to be subject to any sort of exempt or reduced rate payment structure (for example, handicapped placards, or city vehicles). The information relating to the payment for parking spaces managed by the system can also include accurately time-stamped changes in status of the meters or payment systems for individual spaces under management. Such status information may include broken meter, jammed meter, no communication from the meter, expired meter, paid meter, meter under maintenance, or meter unable to accept payment.
The wireless mobile platforms collect and process data that includes the information from the central server and archive engine, the current locations of one or more wireless mobile platforms (if available), the information from prior wireless mobile platforms data inputs (observations) at given locations, as entered by the PEO, or inferred from PEO actions and locations, parking policy information, historical parking trends, distance and or travel time from the current PEO locations to likely violations and presenting the end-user PEO with views of locations which have a high likelihood of being ticketable violations. The wireless mobile platforms may further accept and archive one or more of user actions or user location in the central DB store.
In a further aspect of the invention, the status of the potential violation can include the time of visit by the PEO, issuance of a citation, physical verification of whether a car is present and a space is unpaid, presence of exempting permit or placard, and a reason for the PEO not to issue a citation.
Other presentations of data by the wireless mobile platforms may also be based on or include a maximization of citation revenue, occupancy levels and demand for spaces in a region, street traffic in surrounding areas, other wireless mobile platforms locations or actions, availability of limited resources, such as handicap spaces, or other goals set by the supervisor.
