So Bob, seriously,
Have you shown your traffic engineer a map of Puna? I would sure be interested in hearing a professional opinion.
The more I think about it, it seems to me that there is no way to manage 130 without a secondary road system first. Just too much (current & potential future) traffic; too many intersections too close together.

I voted 130 - 132 intersection. I've had quite a few close calls there and I don't even LIVE on the BI yet!

Bob, what is your source on this?
The general description (I'll dig out the ref) is something like this:
A roundabout requires more space within the intersection.
A signal intersection requires more space leading up to the intersection when there is a right turn lane.
The total difference may be nil.

Here is a basic ref. Others are in agreement.
http://www.tfhrc.gov/safety/00-0673.pdf pages 69-70 explains spatial requirements in detail.
"Although roundabouts typically require more area at the junction
compared to conventional intersections, they may not need as
much area on the approaches."
"...flared roundabouts offer the most potential for
reducing spatial requirements on the approaches as compared to conventional intersections. This effect of providing capacity at the intersections while reducing lane requirements between intersections, known as “wide nodes and narrow roads...”

If all of you just followed the speed limit and not tried to break the law, there would be no need for a speed trap, and the police could attend to more pressing matters.

so.... yesterday when i was driving into Hilo, this car whizzed past me on Hwy 11 past shipman but before Kawailani going north where the speed limit drops considerably. I was doing 30-35 - this car was doing quite a bit more !!!!
The license # was ..... K A P O H O It just tickled me! and reminded me to watch my speed all the time.

yeah...
Some years ago, driving about the same place, near Macadamia Road.
Doing the speed limit on cruise control, hanging close to the right side white line. Steady as we go.
The 'lifted' pick-up nearly sucks me up its tail pipe on the way by going so fast that all I get to see is the bumper sticker, "Slow down! This ain't the Mainaland!"
...somehow, that still isn't as funny as I wish it was.
It was the same stretch of road where, a year or so later, a vehicle like that ran -- from the rear -- straight over a motorcyclist who was out for nice ride on a sunny day. The truck was attempting to pass in the right lane after tailgating a larger vehicle.

All this is meaningless.
I'll say it for the last time: Roundabouts are a traffic control tool. You use the tool that works for the specific job. Just because a hammer can drive a nail in wood doesn't mean it's best for gluing paper, and a glue stick isn't the best tool for pounding a nail.
Did you see the movie “My Big Fat Greek Wedding”? I think roundabouts is your Windex…..
Are roundabouts workable in Puna? Who the heck knows until a
comprehensive review is conducted. Since I have not done any review I can't say they will or won't work. But it appears you have.

Dan, I did show him a roadmap and his only comment was that traffic will always be screwed up because it’s nothing but a giant cultisac. He said the answer is either a helicopter or boat. And that was his laugh for the remainder of lunch, him holding up 1 finger and mouthing “one road?”

Thanks Bob,
That is exactly why I think that PMAR and a secondary road system has to take a priority position in discussing traffic on 130.
ONE ROAD?

cul-de-sac
1. a street, lane, etc., closed at one end; blind alley; dead-end street.
