Toll Plaza Application
In addition to the process server, a plaza application used by the users at the toll plaza to perform daily tasks and manage data at the plaza also takes place. The plaza application based on Web technology. The main application is on the appropriate application server that is installed on the process server. Users access the application from the toll plaza workstation via a specific Web browser. Key features of the toll plaza application are:
- Management of toll plaza system parameters. For example, configuration of payment methods, UFD message on the lanes, making templates for receipts printed on toll lanes as well as other receipts in the system and the receipts printed at the point of sale.
- Configuring the toll lanes. Overall, toll lanes are configured at the central level but some parameters, especially those related to the devices on the lanes can be defined at the plaza level. Also, the operation of individual toll lanes is selected from the toll plaza application.
- Management of declared assets. While working on the lane, it is possible that the cashier gathered a lot of resources and wants the money deposited in the toll plaza. This can be done on the toll lane, by calling authorized staff from the plaza and the declaration of assets. The provisional declaration can also be done in the toll plaza. The cashier at the end of a shift declares all remaining funds raised at the toll plaza. After returning from the toll lane, the cashier logs into the plaza application and enters the collected amount of funds by denomination. After the cashier confirms the declaration, his shift is considered completed. To successfully complete the shift, all incidents related to the cashier’s shift need to be resolved.
- Issuance of predefined cards. If necessary, the user can prepare a set of predefined cards at the plaza for each entry lane. These cards are then issued to vehicles on the entrance lane.
- User management. Some user parameters, such as a user privileges in specific modules can be configured by an authorized person at the toll plaza.
- Funds management station. After all assets are declared by the cashier, authorized user once again verifies the funds and transfers funds in the plaza treasury, after which the fundsare sent to the bank.
- Shifts consolidation. After all incidents related to the shift are resolved, funds are declared and the declaration is confirmed by the authorized user, the shift is ready for consolidation. Shift consolidation functionality is a part of the toll plaza application. After the shift is consolidated, the end of shift report (EOS) is available to the cashier. The EOS includes complete information about all specific events during the shift: all declared assets, expected funding, all logs in the system as well as all incidents during the shift. The report also shows the traffic during shift per vehicle classes in the number of vehicles and the collected and the expected amounts.
- Daily consolidation. After all cashier’s shifts are consolidated, authorized users can implement the daily toll plaza consolidation. After the consolidation is conducted, the data can no longer be changed.
- Data aggregation. Data aggregation is performed when daily consolidation is initiated. The data is stored in aggregate tables that are available for analysis by the rules of a data warehouse. Aggregation allows quick execution of various types of reports with minimal impact on database performance.
- Reports. The tolling system allows the user to run a series of reports, used by the toll plaza personnel for reporting on the daily work. Tollway system makes it easy to run all reports required for work. In addition, the authorized user can create new, personal report and its setting in the application menu at the toll station. By that, the report becomes available to other users through a web application at the plaza.

Lane management and control application runs on one of the workstations at the toll plaza (Lane Status Display Unit - LSDU). This application is in permanent communication with all toll lanes and applications at the toll plaza, and provides an overview of the status of all system components in real time. In LSDU application Almost all the changes to toll lanes can be traced in the LSDU application, such as:

Concessionaire’s center can be located at one of the toll plazas, the headquarters of the concessionaire or at another location that is permanently available to all toll stations through a computer network.
Tolling system at the head office consists of several modules that can be carried out in one or more virtual or physical servers:
Central Communication Server
Base of the central communication server is the IBM Websphere MQ. All messages from all toll plazas are sent to the IBM Websphere MQ, where they for download and processing by the process server. Messages that come to the central communication server refer to the incoming transactions, outgoing transactions, all related information created by the transaction, the user shifts and alarms.
Central processing server
Central processing server includes an application for processing messages received on the communication server. Processing of messages creates transactions, which are then stored in the central database. Account balances are calculated based on the transactions. If an account balance takes on a negative value, the user is placed on the blacklist. Information on the change of status of the account and black list is sent as a message back to all plazas.
