BS EN 15509:2014

What is BS EN 15509 - DSRC interoperability application profile electronic fee collecting about?  

BS EN 15509 focuses on electronic fee collection of interoperability application profile for DSRC 

BS EN 15509 specifies: 

• Payment method: Central account based on EFC-DSRC 
• Physical systems: OBU, RSE and the DSRC interface between them (all functions and information flows related to these parts) 
• DSRC-link requirements 
• EFC transactions over the DSRC interface 
• Data elements to be used by OBU and RSE used in EFC-DSRC transactions 
• Security mechanisms for OBU and RSE used in EFC-DSRC transactions 

Note: It is outside the scope of BS EN 15509 to define: 

• Contractual and procedural interoperability requirements (including issues related to a Memorandum of understanding, mou) 
• Conformance procedures and test specification (this is provided in a separate set of standards) 
• Setting up of operating organizations (e.g., Toll charger, toll service provider, trusted third party, etc.) 
• Legal issues 
• Other payment methods in DSRC-based EFC (e.g., On-board accounts using integrated circuit cards) 
• Other basic technologies (e.g., GNSS/CN or video registration-based EFC). However, BS EN 15509 may be used for defining the DSRC-EFC parts for use in applications that implement a mix of different technologies 
• Non-EFC transactions over the DSRC interface (e.g., CCC and LAC communication, which is defined in other standards) 
• Other interfaces or functions in EFC-systems than those specified above (i.e., Information flows and data exchange between operators or personalization, initialization and customization of the OBU) 

Who is BS EN 15509 - DSRC interoperability application profile electronic fee collecting for?  

BS EN 15509 on electronic fee collection — Interoperability application profile for DSRC is useful for: 

• Toll chargers and service providers  
• Toll service users  
• Electronic fee collection system  
• Information security system  
• Quality assurance tests organizations  
• Compliance checking interrogator operators  

Why should you use BS EN 15509 - DSRC interoperability application profile electronic fee collecting?  

BS EN 15509 provides for a coherent set of requirements of the EFC application and that is intended to serve as a common technical platform for EFC interoperability. 

Using DSRC, BS EN 15509 establishes a minimal degree of technological compatibility for EFC equipment, such as onboard units (OBU) and roadside equipment (RSE). To promote technical compatibility between EFC systems, BS EN 15509 provides an Interoperable Application Profile for DSRC-EFC interactions. 

In addition, BS EN 15509 includes a number of annexes that provide more thorough specifications and examples for the conformity requirements, in order to improve readability and comprehension. 

What’s changed since the last update?  

BS EN 15509:2014 supersedes EN 15509:2007 which is withdrawn. 

This second edition of EN 15509 incorporates the following main modifications compared to the previous one: 

• Amendment of terms, in order to reflect harmonization of terms across electronic fee collection (EFC) standards 
• Addition of a new clause (i.e., Clause 5) on conformance 
• Amendment of the definition of vehicle licence plate number (size constraints and clarification that only Latin alphabet coding is supported) 
• Revision of the informative annex on security considerations (i.e., Annex F), and reference to CEN/TS 16439 on electronic fee collection – Security framework 
• Addition of a new informative annex (i.e., Annex I) on how to use this standard for the European electronic toll service 
• Deletion of informative Annex H, part of the first edition, on Vehicle classification data, as it was deemed obsolete in view of EN ISO 14906:2011 
• Deletion of informative Annex I, part of the first edition, on Using this European Standard for other DSRC based transactions, as it was deemed obsolete in view of CEN ISO/TS 12813 and CEN ISO/TS 13141 
• Amendments to reflect changes to the underlying base standards, with emphasis on backward compatibility with the first edition of BS EN 15509:2014 

For the revision of BS EN 15509:2014, the following principles have been used: 

• Take into account the evolution of some of the underlying standards and technical specifications, i.e., EN ISO 14906:2011, CEN/TS 16439, ISO/IEC 9797-1 
• Maintain compatibility with the EN 15509:2007of BS EN 15509:2014
