1 siemens.com/tolling Back-office system Server Supplies all front-end data. Suitable for any GNSS tolling back-office.

2 Server: The universal back-office for efficient and effective toll collection Server can process data from three different satellite systems as well as from microwave-based data collection systems. This ensures precise data recording and toll calculation even for areas with limited signal quality. The so-called front-end of a satellitebased tolling solution comprises a whole range of systems that all have a common objective: collecting and aggregating tollrelated data that will be acceptable as evidence in court, and preparing them for further processing by the billing system of the toll operator. The most visible of these components is the on-board unit (OBU) installed in the vehicle to collect toll-related data. Less obvious, but just as important is the back-office system. Only if this system is equipped with the necessary intelligence to fulfill its many tasks while being open and compatible in all directions, the toll operator can benefit from secure, effective and profitable toll charging processes. Server is up to this crucial task in every respect and its role exceeds by far that of a simple data provider. More satellites, higher accuracy, higher toll revenues Server has been designed for collaboration with multi-satellite OBUs, i.e. with on-board units that are able to determine their position using all three satellite systems: GPS, GLONASS and GALILEO. Thanks to their multi-satellite capability, the Unit OBUs developed by Siemens generate reliable revenues for the toll operator because they provide accurate positioning data at all times, even in areas with limited signal quality. Test drives through Vienna s historic city center confirmed that a combination of GPS / GLONASS delivers significantly more accurate data than purely GPS-based positioning. As a result, the system reliably distinguishes between closely-spaced neighboring streets, and very rarely encounters problems with signal reception even in areas where highrise buildings obscure the satellite signals. Reliable toll collection in all kinds of tolling landscapes The Siemens back-office system is EETScompliant and thus suitable for use in many European countries. It adapts to the widest range of tolling landscapes and system architectures. Server works just as well with smart-client solutions (geo-data, toll domains etc. are stored in the OBU) as with thin-client solutions (the back-office system holds those data). Neither does it matter if data collection relies solely on satellite signals or if it also integrates microwave-based sensor solutions. Server is absolutely flexible and compatible with a wide variety of technologies and any tolling scenario up to area toll schemes covering all road classes. The back-office system can be integrated smoothly into existing technical system landscapes and easily adapted to new OBU models. Server takes over the four core functions of a tolling back-office: toll calculation as well as management, monitoring and updating of the on-board units. Meets the strictest demands also in terms of data privacy protection The OBU transfers only those data to Server that are required for toll charging, so the privacy of the road users is always protected. The OBU uses powerful cryptographic algorithms for digitally signing all transmitted information. Server comprises a special security module that authenticates and decodes the incoming data telegrams before storing them in a secure memory sector. If required, the original data telegram, including its signature, is stored in the system as well, so that the original data can be retrieved for verification or recalculation purposes, for instance in the event of a legal dispute. For data transmission between the OBUs and Server, the system uses mobile radio technology. In case the mobile radio network is temporarily unavailable, the OBU can store the data even for several days until the communication system is up and running again. Server checks the tolling data for plausibility, completeness and possible repeat transmissions before passing the validated data sets on to the toll operator s central billing system. 2

3 Main tasks of Server and interaction with other components Vehicles subject to toll Unit Server Collection of tolling data Toll system operator Central system Server, the Siemens back-office system for electronic toll collection, can be smoothly integrated into any technical system landscape. It perfectly fulfills its role as link between the on-board units in the vehicles and the toll operator s billing system. With an inclusive range of functions and detection rates of 99.5% percent and higher, provides for reliable and effective toll collection on the basis of legally acceptable evidence. OBU management OBU updating OBU monitoring Value-added services The satellite-based tolling system GNSS GPS GLONASS GALILEO Server DSRC Unit Microwave Monitor by Siemens is the ideal tolling system for today s needs: Its deployment does not require any roadside infrastructure; the system is suitable for any class of road, from motorways down to the smallest country road; and the scope of the tolled road network can be adapted or extended easily and quickly per software update. Our portfolio covers the entire front-end for a tolling solution: an easy-to-use on-board unit ( Unit), a universal back-office system ( Server) and an intelligent enforcement solution ( Monitor).

Typical update events: Distribution of software updates (operating system / OS, firmware and applications) Transmission of configuration data and geo-data to an operator-specified group of OBUs The OBUs are monitored as to: Correct operation Compliance with applicable toll rules Processing of messages on monitoring events such as startup, wakeup, shutdown, user interventions, statistical data on technical interfaces or unexpected exceptions Value-added services can be implemented individually without impacting the regular toll collection functions. Typical value-added services are for instance: Recording of positioning data (Track&Trace) Detection of up to 30,000 zones and generation of messages regarding entry and exit times Messaging service Recording of DSRC transactions for monitoring purposes Recording of other data (e.g. driver interventions, speed etc.) Number of OBUs Currently up to 2,000,000 Detection rate > 99.5% System availability Depending on requirements (typically 99.9%) Detection algorithms Security procedures Central or distributed Zones Waypoint section recognition for the efficient identification of higher-class road networks (Siemens patent) Map matching Multi-zone (numerous small toll zones) Distance calculation RSA 1024, RSA 2048 for signatures and authentication ECDSA 256 for signatures and authentication AES 256 for encryption SHA 2 for secure hashing Support of hardware security modules 4 Note: This specification cannot claim to cover all details of Server or possible product variations.
