The following discusses how the National ITS Architecture provides the transportation service described by this service package. Each numbered item describes the operation of that portion of the service package identified with the corresponding number on the transaction set diagram.
-
The Parking Operator monitors (parking status) and controls (parking operator inputs) and makes requests for current parking service performance data (request for performance data) from the Parking Management Subsystem. Instructions for operation of local parking facilities to support regional traffic management objectives (e.g., which parking lot exits to use) may be sent by the Traffic Management Subsystem to the Parking Management Subsystem (parking lot inputs).
-
The Parking Management Subsystem detects passing vehicles and may identify the vehicles (vehicle characteristics). When a vehicle is detected, a request (vehicle payment request) is made to the Vehicle. The Vehicle requests payment (request for payment) from the Traveler Card. When payment is received from the Traveler Card, a response (vehicle payment information) is sent to the Parking Management Subsystem which responds with a vehicle payment update. The Driver may request advanced payment of parking lot charges (request for service). A message (in-vehicle transaction status) may be sent by the Vehicle to the Driver to confirm payment and/or alert the driver about a payment issue. When a parking payment is made, the status of the payment (roadside transaction status) may be displayed to the Driver with a signal, sign or other equipment on the roadside. In addition, the Parking Management System can provide general parking information to drivers including lot status, parking availability, and directions to available spaces, entrances, and exits ( driver parking information ) through use of dynamic message signs or other technologies.
-
Alternatively, when a vehicle is detected by the Parking Management Subsystem, a request for payment of parking fees (request for payment) may be made directly to the Traveler Card (without first interfacing with ITS equipment onboard the Vehicle). The Traveler Card responds with the payment. The Parking Management Subsystem can send payments as collected or can aggregate them and send on a set schedule or as warranted (payment request) to a Financial Institution. The Financial Institution may respond with the transaction status.
-
When an invalid payment is detected, the Parking Management Subsystem may contact the DMV (license request) to determine the registered owner of the offending vehicle (registration). Violations (payment violation notification) are reported to an Enforcement Agency.
