• plan evaluation trials,
• specify (and install) data capture equipment, and
• analyse, interpret and report visual-behaviour metrics (standards of measurement).

It is applicable to both road trials and simulated driving environments. It is not applicable to the assessment of head-up displays.

It comprises definitions of OBU conformance assessment tests of

– basic dedicated short-range communication (DSRC) L7 functionality,

– EFC application functions,

– EFC attributes (i.e. EFC application information),

– the addressing procedures of EFC attributes and (hardware) components [e.g. integrated circuit cards (ICC) and man-machine interfaces (MMI)],

– the EFC transaction model, which defines the common elements and steps of any EFC transaction, and

– the behaviour of the interface so as to support interoperability on an EFC-DSRC application interface level.

The purpose of this part of ISO/TS 14907 is to define tests that

– assess OBU capabilities,

– assess OBU behaviour,

– serve as a guide for OBU conformance evaluation and type approval,

– achieve comparability between the results of the corresponding tests applied in different places at different times, and

– facilitate communications between parties.

Whereas, ISO/TS 14907-2:2016 defines examples of test cases for DSRC and EFC functionality in Annex C, it does not intend to specify a complete test suite for a certain implementation. To compose a test suite for a specific EFC implementation, the test cases may have to be modified and new test cases may have to be defined and added in order for the conformance test to be complete. It can be useful to take into account the following considerations when defining a complete test suite:

– small range: "exhaustive testing" of critical interoperability/compatibility features,

– large range: testing of boundaries and random values, and

– composite types: testing of individual items in sequence or parallel.

It is outside the scope of ISO/TS 14907-2:2016 to define tests that assess

– performance,

– robustness, and

– reliability of an implementation.

Annex D provides an informative overview of Japanese OBE conformance tests that are based on the ISO/TS 14907 series, in order to illustrate how these can be applied in practice.

ISO/TS 14907-2:2011 comprises definitions of OBU conformance assessment tests of

• basic dedicated short-range communication (DSRC) L7 functionality,
• EFC application functions,
• EFC attributes (i.e. EFC application information),
• the addressing procedures of EFC attributes and (hardware) components [e.g. integrated circuit cards (ICC) and man-machine interfaces (MMI)],
• the EFC transaction model, which defines the common elements and steps of any EFC transaction, and
• the behaviour of the interface so as to support interoperability on an EFC-DSRC application interface level.

It also defines tests that

• assess OBU capabilities,
• assess OBU behaviour,
• serve as a guide for OBU conformance evaluation and type approval,
• achieve comparability between the results of the corresponding tests applied in different places at different times, and
• facilitate communications between parties.

It is outside the scope of ISO/TS 14907-2:2011 to define tests that assess

• performance,
• robustness, and
• reliability of an implementation.

ISO/TS 14907-1:2015 is restricted to systems operating within the radio emission, electromagnetic compatibility (EMC) regulations, traffic, and other regulations of the countries in which they are operated.

ISO/TS 14907-1:2015 identifies a set of suitable parameters and provides test procedures to enable the proof of a complete EFC system, as well as components of an EFC system, e.g. OBE, related to the defined requirements of an application. The defined parameter and tests are assigned to the following groups of parameters:

? functionality;

? quality;

? referenced pre-tests.

An overview of the tests and parameters provided by this part of ISO/TS 14907 is given in 5.1 and 5.2.

ISO/TS 14907-1:2015 describes procedures, methods and tools, and a test plan which shows the relation between all tests and the sequence of these tests. It lists all tests that are required to measure the performance of EFC equipment. It describes which EFC equipment is covered by the test procedures; the values of the parameters to be tested are not included. It also describes how the tests are to be performed and which tools and prerequisites are necessary before this series of tests can be undertaken. It is assumed that the security of the system is inherent in the communications and EFC functionality tests, therefore they are not addressed here. All tests in this part of ISO/TS 14907 provide instructions to evaluate the test results.

ISO/TS 14907-1:2010 is restricted to systems operating within the radio emission, EMC regulations, traffic and other regulations of the countries in which they are operated and it is therefore a requirement that all required equipment approvals from an authenticated and accredited test house have been obtained in order to claim compliance.

ISO/TS 14907-1:2010 identifies a set of suitable parameter and provides test procedures to enable the proof of a complete EFC-system as well as components of an EFC-system e.g. OBE related to the defined requirements of an application. The defined parameter and tests are assigned to the following groups of parameters:

— functionality;

— quality;

— referenced pre-tests.

ISO/TS 14907-1:2010 describes procedures, methods and tools, and a test plan which shows the relation between all tests and the sequence of these tests. It lists all tests that are required to measure the performance of EFC equipment. It describes which EFC-equipment is covered by the test procedures; the values of the parameters to be tested are not included. It also describes how the tests are to be performed, and which tools and pre-requisites are necessary before this series of tests can be undertaken. It is assumed that the security of the system is inherent in the communications and EFC functionality tests, therefore they are not addressed here. All tests in ISO/TS 14907-1:2010 provide instructions to evaluate the test results.

The test procedures can be used for prototype testing, type approvals, test of installations and periodic inspections. ISO/TS 14907-1:2010 defines only the test and test procedures, not the benchmark figures that these are to be measured against.

EFC-systems for DSRC consist, in principle, of a group of technical components, which in combination fulfil the functions required for the collection of fees by electronic automatic means. These components comprise all, or most of, the following:

— on-board equipment (OBE) within a vehicle;

— on-board unit containing the communications and computing sub-functions;

— optional integrated circuit card which may carry electronic money, service rights and other secured information;

— communication between OBE and RSE based on DSRC;

— equipment for the fee collection at the road-side (RSE) containing the communications and computing sub-functions;

— equipment for the enforcement at the road-side;

— central equipment for the administration and operation of the system.

ISO/TS 14907-1:2010 relates solely to OBE and RSE and the DSRC interface between OBE and RSE including its functions to perform the fee collection. All the equipment used for enforcement (e.g. detection, classification, localization and registration) and central equipment are outside the scope of ISO/TS 14907-1:2010.
