Short description

This Abstract Syntax Notation (ASN.1) file precisely specifies the structure of the data used to support implementation of SAE International Standard J2945/3. As part of an international treaty, data defined in US ITS standards are expressed in ASN.1 syntax. ASN.1 Syntax is used to define the data entities or ASN specifications. Using the ASN.1 specification, a compiler tool can be used used to produce encodings as required by the encoding rules identified in the standard (SAE J2945/3 messages are encoded with UPER or JER encoding). Both this file and the SAE J2735 ASN.1 files are necessary to collectively implement the data exchanges described in the J2945/3. The combined library can be used by any application (along with the additional logic of that application) to exchange the data over interfaces conformant to J2945/3.
