Specialist Task Force 282: 

DSRC Conformance Testing in support of Interoperability

Who we are:

Team Leader: Ultan Mulligan
Team members: Fausto Caneschi  
Hans-Joachim Fischer  
Jean-Claude Wattelet  
Vegard Larsen

What we do :

The has STF produced interoperability test suites and related documentation to achieve:

a) Protocol testing for CEN DSRC MAC and LLC layers (EN 12795), and
b) Protocol testing for CEN DSRC application layer (EN 12834) and using selected elements from EN 14906.
The deliverable comprises six Technical Specifications (TS), covering:

  • Protocol Implementation Conformance Statement (PICS) template
  • Test purposes document
  • Abstract Test Suite, and Protocol Implementation Extra Information for Testing (PIXIT) template

The six ETSI Technical Specifications which have been developed by this STF are as follows:

DTS/ERM-TG37-001-1
TS 102 486-1-1
Electromagnetic compatibility and Radio spectrum Matters (ERM);
Road Transport and Traffic Telematics (RTTT);
Test specifications for Dedicated Short Range Communication (DSRC) transmission equipment;
Part 1: DSRC data link layer: medium access and logical link control;
Sub-Part 1: Protocol Implementation Conformance Statement (PICS) proforma specification
DTS/ERM-TG37-001-2
TS 102 486-1-2
Electromagnetic compatibility and Radio spectrum Matters (ERM);
Road Transport and Traffic Telematics (RTTT);
Test specifications for Dedicated Short Range Communication (DSRC) transmission equipment;
Part 1: DSRC data link layer: medium access and logical link control;
Sub-Part 2: Test Suite Structure and Test Purposes (TSS&TP)
DTS/ERM-TG37-001-3
TS 102 486-1-3
Electromagnetic compatibility and Radio spectrum Matters (ERM);
Road Transport and Traffic Telematics (RTTT);
Test specifications for Dedicated Short Range Communication (DSRC) transmission equipment;
Part 1: DSRC data link layer: medium access and logical link control;
Sub-Part 3: Abstract Test Suite (ATS) and partial PIXIT proforma
DTS/ERM-TG37-002-1
TS 102 486-2-1
Electromagnetic compatibility and Radio spectrum Matters (ERM);
Road Transport and Traffic Telematics (RTTT);
Test specifications for Dedicated Short Range Communication (DSRC) transmission equipment;
Part 2: DSRC application layer;
Sub-Part 1: Protocol Implementation Conformance Statement (PICS) proforma specification
DTS/ERM-TG37-002-2
TS 102 486-2-2
Electromagnetic compatibility and Radio spectrum Matters (ERM);
Road Transport and Traffic Telematics (RTTT);
Test specifications for Dedicated Short Range Communication (DSRC) transmission equipment;
Part 2: DSRC application layer;
Sub-Part 2: Test Suite Structure and Test Purposes (TSS&TP)
DTS/ERM-TG37-002-3
TS 102 486-2-3
Electromagnetic compatibility and Radio spectrum Matters (ERM);
Road Transport and Traffic Telematics (RTTT); 
Test specifications for Dedicated Short Range Communication (DSRC) transmission equipment; 
Part 2: DSRC application layer;
Sub-Part 3: Abstract Test Suite (ATS) and partial PIXIT proforma
  

These test specifications are currently being validated by ETSI members: they are developing test tools, implementing the test specifications on these tools, using them to test their products, and providing feedback on the test specifications to ERM TG37.

ERM TG37 has started development of a 2nd edition of these test specifications, in order to take into account comments and corrections which arise from this validation activity.  Early drafts of the 2nd edition of the test specifications are available as follows:

Draft TS 102 486-1-2 V1.2.1
Draft TS 102 486-1-3 V1.2.1
Draft TS 102 486-2-1 V1.2.1
Draft TS 102 486-2-2 V1.2.1
Draft TS 102 486-2-3 V1.2.1

Why we do it:

The European Commission has issued mandate M/338: “Mandate to CEN, CENELEC and ETSI in support of the proposal for a Directive of the European Parliament and of the Council on the widespread introduction and interoperability of electronic road toll systems in the Community" (COM (2003) 132 final). The 3rd bullet of the scope of the mandate states:

“To encourage, in particular CEN, as a matter of priority, further standardisation covering aspects of Digital Short Range Communications (DSRC) using 5.8 GHz microwaves with the objective to enable the provision of on-board units (OBUs) which are interoperable with all current DSRC EFC systems within Europe. In addition to the standards, the ESOs shall develop an interoperability testing scheme permitting the practical verification of interoperability between implementations”

CEN TC 278 has requested that ETSI, as a matter of priority, provide conformance testing suites as essential preparatory work to support interoperability of the CEN DSRC.

The impact of the current proposal is anticipated to be as follows:

Fulfilment of the following EU policies:

  • Assisting in the creation of a single market for DSRC equipment.
  • Interoperability of pan-European tolling. 
  • Facilitating the free movement of citizens within the EU.

Consequential benefits:

  • Speed up toll collection.
  • Smoother traffic flow.
  • Increasing the capacity of motorways.

The introduction of pan-European interoperable EFC based on DSRC opens the possibility for additional road and transport-related applications and services, which enable:

  • Increased road safety
  • Enable police co-operation in the transport sector 
  • Increase supply-chain efficiency.
  • Reduce congestion, delays and accidents.

The provision of this test specification will avoid current provisions for interoperability which are manual and costly, requiring a demonstration by each vendor of interoperability with other vendor’s proposed systems, for each and every installation of an EFC system.

Time plan for the work:

The first edition of the test specifications was published in August 2006.  Work has started in ERM TG37 to produce a 2nd edition, as described above.
