Today we are talking to Jim Brainard, Mayor of Carmel, Indiana. He's the first seven-term mayor. Under his tenure, Carmel has experienced tremendous growth and prosperity. It is considered one of the fastest growing cities in the United States. The population has grown from 25,000 to almost 100,000 in the last 25 years.

Mayor Brainard has implemented numerous environmental and traffic safety initiatives for the City of Carmel. He has encouraged the construction of roundabouts in place of traditional signaled intersections, which have reduced vehicle emissions and accidents with injuries. He is here today to talk to us about the benefits of roundabouts, where his passion for these corner-less intersections comes from, and why Carmel bills itself as the roundabout capital of the U.S.
