The first use case introduced in phase 2 of the project was Payment on Arrival. Besides the parking end customer, the use case involves two platform users: the pay-by-mobile service provider and the enforcement service provider contracted by the operator.
A customer (driver) arrives at the car park / parking area and parks his car. He then opens the mobile application provided by his service provider and enters/confirms relevant information:
Using the provider application, the customer pays the amount due. He has now successfully purchased a right to park here, and a corresponding parking session has been created. The service provider's system sends the details of this parking session (including payment information) to the platform.
An enforcement service officer sees the customer's parked car and wants to check the legitimacy of this parking sessions. Using a handheld device, he types in the license plate number of the parked vehicle. The enforcement system then sends a search request to the platform (including location information and the license plate number). The platform will do a look-up and return all matching data or the information that no data could be found.
Alternative process: if the enforcement service provider's IT system has the capability to temporarily store parking session information, a corresponding subscription for parking session data can be registered. The platform will then pro-actively send all new session information for a particular car park / parking area to the enforcement system backend.
The Pay on check out model enables a customer to log when they park and when they leave. This can be used at the same locations as ‘payment on arrival', the enforcement system will show that a parking session is in progress.
