7.1.1.4: Check for Advanced Tolls Payment

This process shall be responsible for checking to see if the required toll payment has already been made. The process shall determine the existence of an advanced payment for the toll segment(s) by comparing the received payment information with that in the store containing the list of advanced payments. If the payment has already been made then the process shall remove the requirement for local billing and remove the record of the advanced payment from the store. Details of each payment transaction shall be sent by the process to another process with the payment information received from the driver removed. In special situations this process shall pass along wide area alert information to the toll operators that have been received from the Manage Emergency function.
