Modern roundabouts are the safest form of intersection in the world (much more so than comparable signals). Visit http://tinyurl.com/iihsRAB for modern roundabout FAQs and safety facts. Modern roundabouts, and the pedestrian refuge islands approaching them, are two of nine proven safety measures identified by the FHWA, http://tinyurl.com/7qvsaem The FHWA has a video about modern roundabouts on Youtube, or check out the IIHS video (iihs dot org). http://priceonomics.com/the-case-for-more-traffic-roundabouts/ http://priceonomics.com/the-case-for-more-traffic-roundabout... http://safety.fhwa.dot.gov/intersection/innovative/roundabouts/ http://safety.fhwa.dot.gov/intersection/innovative/roundabou... First cost is the wrong way to compare projects. It would be like buying a car without knowing the fuel economy or safety of the thing, just its price to buy. Present Value Life Cycle Cost Analysis (LCCA) is the best way to compare two or more choices. When comparing modern roundabouts to signals for a 20-year life cycle (the standard period), modern roundabouts usually cost less. Costs to compare include: first cost (design/land/construction), operation and maintenance (electricity, re-striping, upgrades, etc.), crash reduction (what’s your/your family’s safety worth?), daily delay (what’s your time worth?), daily fuel consumption (spend much on gas?), point source pollution (generated by stopped vehicles = health cost), area insurance rates (this costs more where it is less safe to drive). Each of these things, and others, can be estimated for any two choices and everyone near or using the project area will pay some portion of all of these costs.
