KenParticipantcopy > paste works.
Or send it to me and I can post it on one of my web servers as a pdf.

hooper1961Memberredblack i am an expert in traffic engineering and deal with this type of data all the time.

miwsParticipantAnd Ken is an expert in computers, and things related, and has offered a way for your data to be posted here!
(Pssssst……click on his name!)

redblackParticipantken, you can haz data now? who has this alleged data? come on! i’m dying to see how lowering speed limits causes more accidents, so i have an excuse next time i get pulled over.
facts, figures, skid mark lengths, tape measures, testimonials, court transcripts, 8 x 10 glossy color photos with the writin’ on the back…

hooper1961Memberredblack – arbitrary speed limits reduce safety for the basic reason motorists disrespect them. someone who travels at an arbitrary low limit can cause frustration to other motorists.
setting speed limits based on recognized Traffic Engineering science improves traffic safety by being more credible and meeting motorist expectations. properly set speed limits improves compliance and uniformity in travel speeds; and thus safety.

AlParticipanthooper – so we should set higher speed limits because drivers want to go faster and because the poor drivers get frustrated? LOL!
Have you read “Traffic?” It discusses lower speed limits in detail and why they are safer and can actually improve traffic flow. Not only that, but motorists are not the only road users. Name one place where traffic is allowed to go as fast as they want with no stringent traffic regulations and that has a low accident/fatality rate per accident (that includes pedestrians, cyclists, farm machinery etc.). And I want a link to your documentation.
Traffic: http://www.amazon.com/Traffic-Drive-What-Says-About/dp/0307264785
I believe I have posted this link before, a good study on speed which you may be referring to: http://www.ibiblio.org/rdu/sl-irrel.html
Note that the study was conducted only on nonlimited access rural and urban highways, not interurban multi-use streets. And the conclusion was that speed limits even on rural and urban highways should NOT be automatically raised, but the idea should be studied to make sure that it’s deemed safe to do so.
“The data collected during this study indicate that there are no benefits, either from a safety or operational point of view, from establishing speed limits less than the 85th percentile speed. This does not mean that all speed limits should be raised. Traffic and engineer investigations should be conducted to obtain an accurate measure of the speed distribution.”
And here’s a good counterpoint:

AlParticipantAnd what does this have to do with the inability of drivers to understand that a two-way left turn lane is NOT a passing lane, even if they *think* someone is just not moving fast enough for them? OFF TOPIC.

I sent the link to hooper so I thought he had posted it.
Appears to be data from Rick Perez at

LindseyParticipantMy boyfriend works at AAA, and do you know what the fleet drivers call those two-way turn lanes? Suicide lanes. EEP.
February 15, 2011 at 2:35 pm #716906
redblackParticipantpop quiz: for fun and learning, what is the longest legal travel distance in the “suicide lane?”
thank you for the mixed data, hooper. is there anything more than 4 examples of federal way semi-arterials – which, if i recall correctly, are mostly one-lane roads? that data shows both increases and decreases in collisions, and it doesn’t give any reasons for the speed limit changes. i.e. were the changes “arbitrary?” or, like the fauntleroy way rechannelization, were surrounding residents truly concerned for their own safety?
btw, SDOT states that safety – sight distance, grade, curves, proximity of cyclists, etc. – is the main reason for 30 mph on admiral.
safety is not “arbitrary.”
