# Message Length Evaluation on IEEE 1609.2 and IEEE 1609.2.1 Messages Source: [Message Length Evaluation on IEEE 1609.2 and IEEE 1609.2.1 Messages]() Collection index: [llms.txt]() Data updated: 2026-06-15T07:08:24.254Z Evaluation of message lengths for IEEE 1609.2 and IEEE 1609.2.1 standard messages. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Message Length Evaluation | | Dataset (including any stated split) | IEEE 1609.2 and IEEE 1609.2.1 Messages | | Metric | Message Length | | Unit | SCALAR | | Direction | Lower is better | | Results loaded | 30 of 30 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [Message Length](): Lower is better; unit: SCALAR. - [SL Value](): Higher is better; unit: SCALAR. ## Recorded results | Method | Message Length | Result date | Report paper | | --- | --- | --- | --- | | IEEE Standards | 122 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 122 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 122 | Not recorded | 6a2f8720d33dfb23e783c04f | | IEEE Standards | 164 | Not recorded | 6a2f8720d33dfb23e783c04f | | IEEE Standards | 212 | Not recorded | 6a2f8720d33dfb23e783c04f | | IEEE Standards | 313 | Not recorded | 6a2f8720d33dfb23e783c04f | | IEEE Standards | 315 | Not recorded | 6a2f8720d33dfb23e783c04f | | IEEE Standards | 416 | Not recorded | 6a2f8720d33dfb23e783c04f | | IEEE Standards | 504 | Not recorded | 6a2f8720d33dfb23e783c04f | | IEEE Standards | 628 | Not recorded | 6a2f8720d33dfb23e783c04f | | IEEE Standards | 764 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 813 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 813 | Not recorded | 6a2f8720d33dfb23e783c04f | | IEEE Standards | 954 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 1553 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 1629 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 1629 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 2444 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 2444 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 3146 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 3171 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 3171 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 3920 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 4163 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 4595 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 5282 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 8880 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 8880 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 9341 | Not recorded | 6a2f8720d33dfb23e783c04f | | Proposed Generalized Pseudonym Scheme | 11378 | Not recorded | 6a2f8720d33dfb23e783c04f | ### IEEE Standards Message Length: 122.
