Electronic fee collection - Charging performance - Part 2: Examination framework (ISO/TS 17444-2:2017)

This document defines the Examination Framework for the measurement of charging performance
metrics defined in ISO/TS 17444-1 to be used during Evaluation and/or on-going Monitoring.
It specifies a method for the specification and documentation of a Specific Examination Framework
which can be used by the responsible entity to evaluate charging performance for a particular
information exchange interface or for overall charging performance within a Toll Scheme.
It provides a toolbox of Examination Tests for the roles of Toll Charger and Toll Service Provider for the
following Scheme types:
a) DSRC Discrete;
b) Autonomous Discrete;
c) Autonomous Continuous.
The detailed choice of the set of examination tests to be used depends on the application and the
respective context. Compliance with this specification is understood as using the definitions and
prescriptions laid out in this document whenever the respective system aspects are subjected to
performance measurements, rather than using other definitions and examination methods than the
ones specified in this document.
The following aspects are outside the scope of this document.
— This document does not propose specific numeric performance bounds, or average or worst-case
error bounds in percentage or monetary units. Those decisions are left to the Toll Charger (or
to agreements between Toll Charger and Service Provider).This document does not consider the
evaluation of the expected performance of a system based on modelling and measured data from
trial at another place.
— This document does not consider the specification of a common reference system which would be
required for comparison of performance between systems.
— This document defines measurements only on standardized interfaces. Proprietary interfaces
are excluded, because it is not possible to define standardized metrics on such system properties.
These excluded interfaces are among others the link between Toll Charger RSE and central systems
in DSRC systems, and the additional sensor input of GNSS modules (inertial sensors, CAN-bus for
wheel ticks, etc.).

Elektronsko pobiranje pristojbin - Izvajanje zaračunavanja - 2. del: Okvirni pogoji za preverjanje (ISO/TS 17444-2:2017)

Ta dokument določa meritve za uspešnost zaračunavanja sistemov za elektronsko pobiranje pristojbin (EFC) na podlagi ravni napak, povezanih z izračuni zaračunavanja.
Ta dokument je osnovni standard meritev. Podrobna izbira meritev je odvisna od uporabe in povezanega konteksta.
Ta dokument opisuje sklop meritev z ustreznimi opredelitvami, načeli in ubeseditvami, ki skupaj sestavljajo referenčni okvir za določitev zahtev za sisteme za elektronsko pobiranje pristojbin
ter poznejši pregled njihove uspešnosti zaračunavanja.
Meritve uspešnosti zaračunavanja iz tega dokumenta so namenjene uporabi v zvezi s katerim koli sistemom zaračunavanja, ne glede na njegovo tehnično zasnovo, sistemsko arhitekturo, tarifno strukturo, geografsko pokritost ali organizacijski model. Določijo se za obravnavanje tehničnih podrobnosti, ki se lahko razlikujejo med tehnologijami in ponudniki ali se sčasoma spreminjajo kot »črna skrinjica«.
Osredotočajo se izključno na rezultat postopka zaračunavanja, tj. na znesek, ki se zaračuna glede na vnaprej izmerjen
ali teoretično pravilen znesek, in ne na vmesne spremenljivke, ki izhajajo iz različnih sestavnih delov
senzorjev, kot je položajna natančnost, doseg signala ali optična ločljivost. Ta pristop zagotavlja
primerljive rezultate za vsako meritev v vseh ustreznih primerih.
Meritve so namenjene obravnavanju informacij, izmenjanih v okviru čelnega vmesnika in
vmesnikov interoperabilnosti med izvajalci storitev cestninjenja, pobiralci cestnine in uporabniki cest ter tudi na
celotni ravni.
Opredeljene so meritve v zvezi z naslednjimi izmenjavami informacij:
– poročila o zaračunavanju,
– izjave o plačilu cestnine,
– podatki o obračunavanju in povezani podatki o dogodku,
– zahtevki za plačilo na ravni uporabniških računov storitve pobiranja cestnin,
– uporabniški računi,
– celotne meritve, ki ocenijo splošno delovanje postopka zaračunavanja.
Podrobnosti o utemeljitvi te izbire so navedene v točki 5.1.
Predlagane meritve so posebej namenjene zaščiti interesov udeležencev v sistemu cestninjenja,
kot so izvajalci storitev cestninjenja, pobiralci cestnine in uporabniki cest. Meritve je mogoče uporabiti za opredelitev
zahtev (npr. za zahteve za predloge) in ocenjevanje uspešnosti.
Ta dokument določa dve vrsti primerov, v katerih je potrebna ocena uspešnosti:
a) kadar se ocena izvaja v omejenem časovnem obdobju, na primer pri oblikovanju
zahtev in oceni sistemov za namene pridobivanja in preskušanje ustreznosti,
pri čemer se te vrste ocene imenujejo vrednotenje,
b) kadar je ocena potrebna v okviru stalnega nadzornega postopka v celotni življenjski dobi
sistema, da se validirajo ravni pogodbene storitve, opredeli goljufija ali okvara ali
podprejo stalni postopki vzdrževanja in izboljšave uspešnosti. Ta vrsta ocene se
imenuje spremljanje.

Introduction
Electronic tolling systems are complex distributed systems involving critical technology such as
dedicated short-range communication (DSRC) and global navigation satellite systems (GNSS), both
subject to a certain random behaviour that may affect the computation of the charges. Thus, in
order to protect the interests of the different involved stakeholders, in particular Service Users and
Toll Chargers, it is essential to define metrics that measure the performance of the system as far as
computation of charges is concerned and ensure that the potential resulting errors in terms of size and
probability are acceptable. These metrics will be an essential tool when establishing requirements for
the systems and also for examination of the system capabilities both during acceptance and during the
operational life of the system.
In addition, in order to ensure the interoperability of different systems, it will be necessary to agree on
common metrics to be used and on the actual values that define the required acceptable performances
although this is not covered in this document.
This document is defined as a toolbox standard of examination tests plus a method for defining and
documenting Specific Examination Frameworks to meet specific needs. The detailed choice of the set
of examination tests within an Examination Framework depends on the application and the respective
context. Compliance with this specification is understood as using the definitions and prescriptions
laid out in this document whenever the respective system aspects are subjected to performance
measurements, rather than using other definitions and examination methods than the ones specified in
this document.
ISO/TS 17444-1 defines a set of charging performance metrics with appropriate definitions, principles
and formulations, which together make up a reference framework for the establishment of requirements
for EFC systems and their later examination of the charging performance.
These charging performance metrics are intended for use with any toll scheme, regardless of its
technical underpinnings, system architecture, tariff structure, geographical coverage, or organizational
model. They are defined to treat technical details that may be different among technologies as a “black
box”. They focus solely on the outcome of the charging process, i.e. the amount charged in relation
to a pre-measured or theoretically correct amount, rather than intermediate variables from various
components as sensors, such as positioning accuracy, signal range, or optical resolution. This approach
ensures comparable results for each metric in all relevant situations.
The metrics are designed to cover the information exchanged on the front-end interface and the
interoperability interfaces between Toll Service Providers and Toll Chargers, as well as information on
the end-to-end level.
Metrics for the following information exchanges are defined:
— Charge Reports;
— Toll Declarations;
— Billing Details and associated event data;
— Payment Claims on the level of user accounts;
— End-to-End Metrics which assess the overall performance of the charging process.
The proposed metrics are specifically addressed to protect the interests of the actors in a toll system,
such as Toll Service Providers, Toll Chargers and Service Users. The metrics can be used to define
requirements (e.g. for requests for proposals) and for performance assessment.

Toll schemes take on various forms as identified in the ISO 17575 series and ISO 14906. In order to
create a uniform performance metric specification, toll schemes are grouped into two classes based on
the character of their primary charging variable:
— charging based on discrete events (charges associated to the fact that a vehicle is crossing or
standing within a certain zone);
— those based on a continuous measurement (duration or distance).
In all these toll schemes, tolls may additionally vary as a function of vehicle class characteristics such
as trailer presence, number of axles, taxation class, operating function, and depending on time of day or
day of week, such that, for example, tariffs are higher in rush hour and lower on the weekends.
With this degree of complexity, it is not surprising to find that the attempts to evaluate and compare
technical solutions for Service User charging have been made uniquely each time a procurement
or study is initiated, and with only limited ability to reuse prior comparisons made by other testing
entities.
Examination Framework
The Examination Framework that is defined in this document is designed for measuring the metrics
defined in ISO/TS 17444-1. The general aim is to achieve a maximum co
