Prepare structures based on UN ECE Consolidated Resolution

• UN ECE/TRANS/WP.29/78/Rev.3 (2014) https://unece.org/fileadmin/DAM/trans/main/wp29/wp29resolutions/ECE-TRANS-WP29-78-r3e.pdf
• UN ECE/TRANS/WP.29/1045 (2005) https://unece.org/fileadmin/DAM/trans/doc/2005/wp29/TRANS-WP29-1045e.pdf

…or, identify if someone has already provided SDMX structures with these categories.

The documents provide a variety of different concepts that could be collected in concept schemes, and codes that could be collected in code lists. For example:

2.4. Category O - Trailers (including semi–trailers)
2.4.1. "Category O1": Trailers with a maximum mass not exceeding 0.75 tonnes.
2.4.2. "Category O2": Trailers with a maximum mass exceeding 0.75 tonnes, but
not exceeding 3.5 tonnes.
2.4.3. "Category O3": Trailers with a maximum mass exceeding 3.5 tonnes, but not
exceeding 10 tonnes.
2.4.4. "Category O4": Trailers with a maximum mass exceeding 10 tonnes.
2.4.5. Furthermore, trailers of categories O2, O3 and O4 are of one of the three
following types:
2.4.5.1. "Semi–trailer": […]
2.4.5.2. "Full trailer": […]
2.4.5.3. "Centre-axle trailer": […]

…could be converted to:

• Concepts TRAILER_MASS, TRAILER_TYPE among many others in a concept scheme UN:CS_CONCEPTS(1.0).
• A code list UN:CL_TRAILER_MASS(1.0) with codes O1, O2, …
• A code list UN:CL_TRAILER_TYPE(1.0) with codes Semi-trailer, Full trailer, …
• etc.

These would then allow to use these to describe the structure of data in the TDC.

@khaeru Can you add a bit more context to this task if possible? Is it about the updated manual that Fadiah mentioned in Geneva?

[khaeru]

Hi, yes—so the “Glossary for transport statistics” that @fachmadi shared (see also https://gist.github.com/khaeru/8c91ee67c41f75c7db4918813bfce186) is different from these. These were rather suggested by @PierpCazzola (in May last year, or earlier, given the issue date) as just one existing/common categorization of vehicles that it would be useful to reference and perhaps apply within TDC.

I don't know precisely how they are related; for instance, I am flipping through the 2019/5th edition glossary I was given, and I don't see many specific references to the above documents. They may align closely or differ.

I will update the description with a few more bullet points.

Hi, The fact that there is a discrepancy between vehicle categories used in UN automotive regulations and what is in the glossary is part of a problem that shall be resolved by those in charge of the glossary and the UN regulations. The UNECE happens to be in both. Pier

Thanks for the extra detail. In any case, we should just preserve the existing lists and any future lists as distinct items (or versions of the same item) so that it can be clearly and unambiguously stated which one applies to certain data; and so we can identify if/when data needs to be transformed from old to future categorizations.

Good morning colleagues.
Thank you for the discussion. As I mentioned earlier, we are currently in the process of updating the Glossary, where vehicle categorisation will be aligned with the latest version of RE.3. As I discussed earlier with @khaeru , I will ensure that the contents of the new Glossary are SDMX ready.
