Dr J, how many of the roundabouts do you propose for 130 to Pahoa? And what will the speed limits be before and during the turns? How would a loaded gravel truck do speedwise without spilling, especially on his return to straight?
One has been converted as such in Carlsbad Cal., and on a 25 mph, tree lined street with considerable cross street traffic, it worked well, and prettied up the intersections. But that was a 25 mph zone both ways.
On 130, that would be ridiculous, with our mix of trucks etc. each circle would break your momentum and you have to accelerate and slow down for each one. Plus the extra tire wear from all the unnecessary turning, or do we slow to 15, and accelerate to 50 how many times, wasting gas and polluting the environment. That's if you don't get stuck behind a loaded semi and get to breathe his fumes while getting back to speed.
Sounds to me like somthing an oil baron would pull off. How many turns?
