Agreed, Bob.
In the case of Highway 130, what is needed is an objective comparison of roundabout versus traffic signal versus stop sign at every intersection from Kahakai to Shower.
A roundabout will be better for some of those intersections and for some it will not, in terms of the first priority, safety; as well as traffic flow, construction cost, maintenance cost, and operating cost.
This comparison must be a basic decision tool for the community and DOT -- simply, a decision tree that says, "Does a roundabout work at this site?", "If yes, then build it; if no, then do not build and instead go to the next alternative..." -- stop sign or signal, and so forth.
