Talk:Raised pavement marker

message: The content in this article was transferred in from Cat's eye (road), because it became clear to everyone involved that the American raised pavement marker and the British cat's eye are really two different things.  --Coolcaesar 01:27, 25 August 2005 (UTC)
replies: text: The orange marker is not cat's eye as invented by Percy Shaw, and that is what the bulk of the article is about. take a look at the picture here for a proper side on view of a cat's eye. Also look at the diagrams from the patent drawings linked in the article and you will see signficant differences. Jooler 15:29, 9 July 2006 (UTC)

message: I was going to suggest renaming the page to Botts dot, but given the content, this does not seem correct.  Stimsonite Markers appears to be the main brand for the reflectors listed on this page and they are not called botts dots on the Ennis Paint] web site.  They also do not list the round dots which are what I thought were the bots dot's.  So it appears that this page is combining two different items into a single definition.  I think these two need to be split out.  At that point we can see if this should be retained as an article or split out into two articles.  Are there any definitive sources so we can clean this up?

replies: text: The problem is that Botts dots are a subset of raised pavement markers.  Also, I'm not sure if there's any need for a split since the article is really not that long yet.  --Coolcaesar 02:04, 18 July 2006 (UTC)
replies: text: I have added some other brands into this article.  I'm not sure if they used to be, but they are currently not referred to in the generic as Stimsonite Markers, lest that threaten the trademark.  For example, 3M definitely is a manufacturer of retroreflective raised pavement markers.  Also, I do believe it is common to refer to both retroreflective and non-reflective raised pavement markers informally as "Bott's Dots" but in the industry they are designated more specifically by their formal names.  Vegaswikian -- the reason why you won't find the round dots on Stimsonite's website is because they don't manufacture or market that product.  However, they are still considered Bott's Dots.  According to the Caltrans website, companies that market the round non-reflective type are: Apex Universal, Glowlite, Hi-Way, Interstate Sales, Novabrite, and Three D Traffic Works.

replies: text: Thanks for the cleanup.  We needed someone with some knowledge in the area to clean it up.  Since the Cat's eye stuff was all removed to an article, I have also moved the botts dots to one.  Vegaswikian 08:31, 14 January 2007 (UTC)
thread_title:  Move of page or is it a split or a rewrite 

message: 3M is listed on the page as a supplier of these.  I could not find this on their web site.  Anyone have the exact URL? Vegaswikian 21:30, 17 July 2006 (UTC)
replies: text: Try typing "3M raised pavement marker" into Google.  The first link is this one. .  --Coolcaesar 02:02, 18 July 2006 (UTC)
replies: text: Those all appear to be reflective and not Botts dots.  I did find one state web site that lists Gulf Industries, Inc. as a supplier of what appears to be the dots.  However their web site does not provide any details.  Vegaswikian 02:59, 18 July 2006 (UTC)
replies: text: Just figured it out.  Try searching Google for "ceramic pavement marker" and "non-reflective pavement marker."  Apparently that's what they're formally called by engineers nowadays.  --Coolcaesar 12:37, 18 July 2006 (UTC)
replies: text: Thanks again.  Do you know if the Botts dots really come in a square one or are they all based on the Stimsonite markers?  I'm far from an expert in this area and just trying to understand this.  Vegaswikian 14:44, 18 July 2006 (UTC)
replies: text: No, I'm not sure how Heenan's work relates to Botts's work.  I know that the general concept (of using raised retroreflective markers) was already well-known in the 1950s because of Percy Shaw's work with cat's eyes in the UK, but it's not clear whose square design Caltrans was using between the round clay dots since Heenan's design hadn't been invented at the time Botts was doing his research.  There's probably some magic document in the state archives in Sacramento that will resolve this issue, but I don't have the time right now to go look for it.  --Coolcaesar 03:56, 19 July 2006 (UTC)

message: Delineator is currently a redirect to Cat's eye (road). We need to get the delineator text out of this article and into its own article.  While delineators serve a similar purpose as raised pavement markers (to channelize traffic), hitting a delineator will do a lot more damage to both pylon and car than hitting a raised pavement marker! I have also raised this issue at Talk:Cat's eye (road).--Coolcaesar 08:44, 5 August 2006 (UTC)

message: Please see WP:NAME. Wikipedia policy is to use the most common name for an object.  The term actually used by both transportation engineers and road geeks is raised pavement marker.  --Coolcaesar (talk) 15:55, 27 September 2010 (UTC)
thread_title:  Correct title for article 

message: There's another type in some parts of England, that have admirable simplicity, and durability as well as being equally effective when approached from any angle - a full 360 degrees. They are a very simple design: apparently a 1-piece glass moulding with a 1-inch hemisphere above the road surface and a 4-inch hemisphere below the surface (the two hemispheres being co-axial and co-planar). Presumably the lower hemisphere is 'silvered' before embedding in the tar.
Looks like Tiger Eye, Siglite from Seih-Ying, Taiwan

message: US Patent 1872643 filed May 17, 1930 by Evan P. Bone. Granted August 16, 1932. Predates the UK patent by a couple of years. http://patimg1.uspto.gov/.piw?PageNum=2&docid=01872643&IDKey=BF2C758CC529 A design for an automotive reflector but also saw wide use in the USA for "marbles" in road signs before the invention of plastic cubical retroreflectors like Stimsonite's No. 8 (also commonly used in the 1950's in automotive tail lights).

message: In Egypt, they are often used (quite unsuccessfully) to force drivers to reduce their speeds. I'm wondering if this is the case elsewhere.

message: I see plenty of reliable sources on Google Books for all those names except for two: convex vibration line and road turtle.
It looks like according to Google Books that the usual meaning of "road turtle" is a turtle that has been run over on a road. 
Any objections before I take out the trash? --Coolcaesar (talk) 21:29, 2 January 2021 (UTC)
