I do not think this concept merits its own article, and believe it is adequately covered at Speed limit#Maximum speed limits, which actually goes more into depth than this standalone article (which is nothing more than a dictionary definition). This article should be redirected to that section. Trainsandotherthings (talk) 00:43, 16 May 2024 (UTC)[reply]

Redirect to Speed limit#Maximum speed limits per nom. Stubby tidbit of information more at home in an article section. BD2412 T 01:53, 16 May 2024 (UTC)[reply]
Merge with Speed limit#Maximum speed limits: Agree that this fails DICDEF. The citations here can be merged. voorts (talk/contributions) 15:29, 18 May 2024 (UTC)[reply]
Keep Agree that article should be expanded, but deletion is not cleanup. I will work to expand the stub soon and welcome help from others.

The 85th percentile speed is a policy decision that was perhaps in the past considered a minor component of Speed limit#Maximum speed limits. However it is now being covered by reliable sources as a large component of Transportation safety in the United States, with criticism directed solely at the 85th percentile rule (as opposed to high speed limits in general) and laws being written to eliminate the rule (but not high speed limits). The rule has significant coverage and meets GNG.

Subject deserves its own article to track the development of 85th percentile rule usage and decline, as covered by reliable sources. Just like Parking mandates is a different article from Parking.

Merge to Traffic engineering (transportation) - per nom, this is a stubby DICDEF; however, merging into traffic engineering (transportation) seems better than putting this in Speed limit. If kept, it should be retitled "85th percentile speed rule" or the like. Walsh90210 (talk) 15:30, 25 May 2024 (UTC)[reply]
Comment I've now expanded the stub past DICDEF, including an academic paper dedicated to this subject and recent Federal Highway Administration lobbying specifically on this rule. PK-WIKI (talk) 20:49, 25 May 2024 (UTC)[reply]

Merge to Speed limit or grow. Traffic engineering (transportation) seems like the wrong merge target; it doesn't actually mention speed limits at all right now. It should at least link to speed limit; setting speed limits is one of the tasks of traffic engineering. I was going to suggest merging into Speed limit#Maximum speed limits as a good outcome, preferable to deletion, as this is an important safety topic.

If the article isn't going to get any bigger than it is now, merging would be appropriate. If we're going to start adding maps that track where in the world this rule is used, and follow along with reform efforts, a standalone article is appropriate. I don't mind merging and then re-splitting later if the section in question gets too long.

I'll also note that a third article covers the same topic, V85 speed. That should be merged into this article if kept, or its merge target if not. -- Beland (talk) 00:42, 1 June 2024 (UTC)[reply]

Merge to Speed limit per voorts. Speed limit is a suitable merge target; in essence this information is a partial answer to the question "how are speed limits chosen?" which is a logical topic for that article. Triptothecottage (talk)
