Carmel is a city in Indiana. It is adjacent to a very big city, Indianapolis (pop. 875K). Carmel has more roundabouts than any other city in the U.S. Here are some results of the city's aggressive program of replacing signalized intersections with roundabouts (155 of them since 1996):

• 40% reduction in accidents
• 80% reduction in injury accidents
• $180K reduction in long-term maintenance costs per roundabout
• 24K gallons of fuel saved per roundabout (plus air emissions benefit)

The population of Carmel, Indiana, is roughly the same as our population here in Arden Arcade (pop.100K). Arden Arcade is an unincorporated community that is adjacent to a very big city, Sacramento (pop. 525K). Arden Arcade has zero roundabouts, but plenty of signalized intersections. In part due to the County's massive road maintenance backlog ($1.4B),  Arden Arcade is known for bad pavement and an inordinate number of traffic accidents, along with pedestrian and bicycle un-friendliness.  Would Arden Arcade benefit from replacing signalized intersections with roundabouts? Well, sure. But it will never happen as long as the County is running the show. Right?
