The Way I See It!
I am an Ultra-Conservative, Alpha-Male, True Authentic Leader, Type "C" Personality, who is very active in my community; whether it is donating time, clothes or money for Project Concern or going to Common Council meetings and voicing my opinions. As a blogger, I intend to provide a different viewpoint "The way I see it!" on various world, national and local issues with a few helpful tips & tidbits sprinkled in.
More to Think About on Roundabouts!
Watch how they twist the data to show how much better the roundabouts are.
Caution statistics can and will be slippery! But we will try and put down some sand for traction.
Over 7 years 7 of 13 accidents were injury accidents. With 15 months 3 injury accidents.
Let's do some math. We are going to extrapolate some data forecasting with ratios.
7 years x 12 months = 84 months
84 months/7 injury accidents
15 months/3 injury accidents
So to do this we need a common denominator of 21
84 months x 3 = 252 months and 7 injury accidents x 3 = 21 injury accidents
Compared to
15 months x 7 = 105 months and 3 injury accidents x 7 = 21 injury accidents
So in the timeframe of 105 months (8 years 9 months) the roundabout will produce 21 injury accidents and it will take 252 months (21 years) for an intersection with stoplights to have 21 injury accidents.
With a roundabout, we can say that in 8 years 9 months = 21 injury accidents
Or
Compared to the Intersection with stoplights to have 21 injury accidents it will take
21 years!
Are roundabouts dangerous? So far, yes
Of the 44 reportable and nonreportable accidents at Rock Ridge/Moorland in a 15-month period from the end of 2007 through January 2009, only three were injury accidents, he said. That is far lower than the seven out of 13 accidents that were injury accidents at the Rock Ridge and Moorland intersection with traffic lights, Rieder said. Those 13 accidents happened over a period of seven years.
Yes, you can say some of them are just because the roundabout is new, but the data is the data we have and should we see an improvement with increased repeat use? We should!
Will we see an increase in safety overall with cars just from design improvements? Yes, we should and have. That is always a flaw in drawing out data, the cars keep getting safer. So is it really the roads that are just safer, or is it more than that?
Notice what is missing in the statistics below!
Roundabouts
Modern roundabouts are the newest form of intersection in the
Roundabouts provide safe and efficient traffic flow and make use of extensive safety and traffic research conducted over the past 25 years in other countries.
Today's roundabouts are much smaller than the "traffic circles" of earlier years.
Roundabouts move traffic safely through an intersection because of:
Slower speeds
Fewer conflict points
Easier decision-making
Studies by the Insurance Institute for Highway Safety (IIHS) show that roundabouts provide a:
90% reduction in fatal crashes
76% reduction in injury crashes
30-40% reduction in pedestrian crashes
10% reduction in bicycle crashes

Do they increase or degrease accidents overall? That data is missing!
Why would they omit that statistic and fact?
Would it help or hurt the push for European style turnabouts that in the
