Toll Collection

The Toll Collection Subsystem provides the capability for vehicle operators to pay tolls without stopping their vehicles using locally determined pricing structures and includes the capability to implement various variable road pricing policies. Each transaction is accompanied by feedback to the customer indicating the general status of the customer account. A record of the transactions is provided to the Toll Administration Subsystem for reconciliation and so that the customer can periodically receive a detailed record of the transactions.

Security Considerations

The primary security consideration for the Toll Collection Subsystem relates to the financial information collected in the field that is sent to the Toll Administration Subsystem, and to any personal information associated with the financial transactions. Electronic toll payment needs to have a relatively high degree of confidentiality in order to safeguard the information. Additional security sensitivity is for the personal information associated with electronic accounts. In addition, it is important that the information is available from the Toll Collection subsystem to the Toll Administration subsystem in order to ensure that tolls are properly accounted for. The integrity of the information is also important to consider in order to prevent disruption of toll fee collection operations.
