Talk:Rumble strip

message: "Occasionally in the UK, they may be painted horizontally across the road in groups of 5 as a traffic calming method, to slow drivers down."  I imagine painted-on strips wouldn't actually rumble.  Am I understanding this sentence wrong? --Mdwyer 22:20, 28 February 2006 (UTC)

-I do not know. But I can tell you my Grandfather claims he invented the machine for making them. He did work with a large International Construction company from at least the 50's through to the early 2000's. (Yes he really retired well into his 70's). I am not going to name names but the company does a lot of paving in North America and other countries. I don't know if it is true or not but he says that it was patented or trademarked(I"m not sure which) through the company and not his name. Magu (talk) 10:01, 24 September 2009 (UTC)

The outcome would likely be different in both scenarios. The article does not seem to mention or consider this.  —Preceding unsigned comment added by 87.232.36.109 (talk) 20:46, 17 December 2010 (UTC)

message: I believe the alternating coloured strips on the edges of race tracks are also called rumble strips and function in a similar fashion.

thread_title:  Race Tracks? 

message: I have always wondered: for all their benefits, won't rumble strips eventually make (that part of) the road more brittle, as over time, the elements (rain — don't the strips fill up with water during and after rain? — sleet, snow, plus the passage of ever more autos over them) will collapse (at least some of) the strips. I'm curious to see if that doesn't make sense and how (if at all) the planners provide for that not to happen. Asteriks (talk) 12:30, 3 December 2009 (UTC)

thread_title:  Part I - Alex's incorrect claim of "controversies" by a single editor

message: Hi Alex,
I was examining one reference #6 - The hidden persuaders - Contractor magazine, Vol 30 No 9, October 2007.  You didn't provide the link, but its: http://www.contrafedpublishing.co.nz/Contractor/The+hidden+persuaders.html
Two key points from the journel are:
"• Reports of rumble strips’ effectiveness had shown a  two to 44 percent reduction across all types of crashes, with an average reduction of 27 percent. 
• Shoulder rumble strips had reduced “run off road” crashes by 20 to 80 percent, with an average of 32 percent (42 percent for fatal crashes)." 
In the Wiki paragraph you reinserted states:
"New Zealand used rumble strips in small applications since the late 1980s, and started a larger program in 2004. Research in the country indicated that lane delineation with rumble strips reduced crashes by an average of 27% over all crash types and studies, with types of crashes such as "run off road" being reduced by up to 80% in some studies. Centre-line rumble strips showed similar effects.[6]"
This paragraph doesn't reflect the journel. There's no mention of "two to 44 percent"; or the 20 to 80 percent versus up to 80%.  
Also, "20 to 80 percent, with an average of 32 percent" seems questionable.  The median of 20 to 80 is 50, but the stated average is 32 and this indicates that 80 is an extreme outlier and is suspect.
The Wiki paragraph is not a balanced reflection of the reference as it emphasizes the questionable high-end without mentioning the ranges.
Also, another quote from the journel:
"• Efforts to lower the road toll in New Zealand tend to focus on the numbers killed each year and to publicise punitive measures taken against two of the main perpetrators: speeding and intoxicated drivers."
Were there other crash reduction campaigns (i.e. increased policing, eudcational programs, "to publicise punitive measures") in conjunction to the rumble strips that may have contrituted to the reduction similar to the New York Thurway study that initially claimed an 70% reduction, but later admitted that there were other initiatives that contributed to the reduction. (see New York Times article)?
http://www.nytimes.com/1998/06/26/automobiles/autos-on-friday-safety-achilles-heel-for-gasoline-trucks.html?sec=&spon=&pagewanted=all
This paragraph appears unbalanced, so can it be removed?

thread_title: Part II - The hidden persuaders - a contractor magazine

message: Hi Alex,
I see you just inserted (May 23, 2010) new material from a Ghana study.  However, it appears to be a misrepresentations of the reference.  
: You wrote (May 23): "Rumble strips can be used to reduce speed. In Ghana, rumble strips were installed on the main Accra-Kumasi highway and reduced crashes by about 35% and fatalities by about 55%. By reducing speeds the environment for and safety of pedestrians and cyclists was improved. [5]"
: The article states: "While the enforcement of speed limits by traffic police may not be affordable for most developing countries, rumble strips and speed humps were found to be effective on Ghanaian roads."  
Also, contrary to your take on the article there is no mention of cyclists' safety.
Furthermore, what kind of rumble strip is the Ghana study involve?  Shoulder rumble strips or tranverse rumble strips?  This lack of detail doesn't enhance the article.  
Ghana is a third world country with low levels of policing (and I believe the motor vehicle fatality rates there is very high although I'm having trouble find accident stats for that country - probably because its a third world country). So, the implication is that they will produce the similar results elsewhere (with high levels of policing) is suspect.
Rumble strips should only be installed in locations where they are identified problems and there is a reasonable level of certianity they will be effective in reducing those problems.

thread_title:  A Re: To the noice complaints 

message: Why is there a huge section of this article that just basically states that rumble strips don't prevent run-off-road accidents? It seems like too much weight is given to this content. In fact, it's essentially an anti-rumble strip rant full of synthesis and bias. SwarmTalk 15:13, 24 June 2010 (UTC)
replies: text: I was taking while to think about this issue, but it seems, my opinion be damned, you've gone ahead and reversed my action. Oh well, I'm not interested in edit warring over it, so I'll leave it for now. I hope you used the undo feature, and didn't rewrite all of that. Anyway, I have no emotional interest in the topic, but if someone else raises any concerns I might return. I certainly hope you don't try to "lock down" your content by fighting any changes that someone makes to it. Anyway, I'm sure you have nothing but the best intentions.

I don't doubt that there was lobbying from the Amish community based on some snippets/half references I've found but it seems a bit errm.. odd to have this section here. Unless I can find a better ref or *some* reason that this needs a breakout section relevance I'll be proposing to slice the section out and integrate the factoid into the top section on opposition (basically by x-reffing M-DOT's policy on horse/buggies and rumble strips) Fuzi (talk) 07:24, 11 October 2012 (UTC)

I was going to put that in the history section but I'm not sure of the context – it implies that it was the beginning of side-of-the-road usage but doesn't state it outright, at least in the abstract. Mapsax (talk) 01:13, 6 February 2022 (UTC)
