Table based Tariff
A tariff function that is not depending on continuous parameters like measured distance (see DBC!) or time durations. Such tariffs are typically implemented and communicated by tariff tables (look-up tables).
A tariff (short for tariff class) denotes the exact case (as defined in a tariff scheme) that was applied to calculate a usage fee.
A mapping of tariff parameters into price (incl. currency), tariff identifier and position text.
The business rules of how the toll is calculated. The tariff model is also relevant for the definition of the Toll Objects.
Parameters influencing the height of a toll fee, i.e. parameters of the tariff function. One distinguishes fixed, variable (trip specific) and toll object related tariff parameters. Tariff parameters can be discrete (classified) or continuous.
The tariff scheme defines in which way an infrastructure is charged. The tariff scheme is driven by a charging policy.
Time Distance Place (road pricing)
See Smart Client. Term "thick client" shall be avoided.
An OBU implementing central toll event detection. Thin clients are believed to have a lower hard- and software complexity and costs than thick clients.
A written or virtual (electronic) acknowledgment documenting that a user is allowed to use a certain service. Used in the Declarative Scheme. It contains a number of Charge Data Records and contains further information such as address details and the date of issue.
Time to First Fixe (TTFF)
Time between switch on of GNSS Receiver and first calculation of navigation solution (Start-up time).
A fee charged for the usage of constructions such as roads bridges and tunnels.
Within the European standardisation context the abstract roll 'Toll Charger' is the entity selling the road usage and is receiving tolls from road users. He is responsible for levying toll in a toll domain (a motorways network a bridge, a tunnel, all roads on a geographical area.). He claims payment from the Service Providers for the road usage of its clients which is guaranteed by a payment guarantee for genuine claims.
To collect a fee for the usage of constructions such as roads bridges or tunnels. Within the European Context Toll Charging means providing a transport service (road usage) to a Road User and charge a fee for this. The responsibility for levying toll in a toll domain is part of the Role and results in claiming payment.
Toll Charging Schemes
The charge-relevant parameters that exist in a particular electronic toll charging system (time, distance, segment-based charging, area-based charging and/or Vehicle Characteristics).
Toll Data Record (TDR)
A data record produced by a toll frontend that contains all relevant information for a toll event (typically a detected toll object or a booking record). TDRs are not necessarily priced but carry all information (tariff parameters) for rating the event and relate it to a customer account or anonymous payment.
A toll event is both the activity and the result of identifying a vehicle to be subject to a tolling fee (as defined by a toll object) or the result of a manual booking (declaration). A toll event is represented by a toll data record (TDR). A toll event can have various statuses (active, rated, closed, and others) depending on its stage in usage and processing. See also Used Toll Object.
Toll Event Detection
The translation of positioning data or beacon signals to toll events.
A distinguished part of a toll road network. A toll object is used within a tariff scheme to define a physical object (part of an infrastructure) for which the usage is charged. Moreover the toll objects definition includes the objects tariff parameters (including an ID and possibly name) as well as validity period information.
Toll Object Usage
Toll relevant usage of a toll object.
Toll Road Network
An area or part of a road network where a toll regime is applied.
A particular set of use cases within the electronic toll charging system. Example: Description of a Road User's interaction with the electronic toll charging system who uses an OBU in prepayment mode.
Toll Service Provider
A subsystem delivering charge data records (CDRs) and possibly toll data records (TDRs) to charging and enforcement systems.
A limit on the OBU. When this monetary limit is reached, the OBU attempts to send charge data to the central system.
Transport Service Provider (TSP)
The sub-entity of Toll Charger that provides a transport service to the user (i.e. the road operator road authority the "owner" of the road infrastructure)
