Transight LLC can help your agency quickly determine whether an intersection is a good candidate for a roundabout or neighborhood traffic circle. We have produced geometric designs for both types of center-island intersections, and capacity/delay analyses of proposed roundabouts. We also offer a short, entertaining presentation to educate community groups about the types and advantages of center-island intersections.

John Ciccarelli was a reviewer for the FHWA publication Roundabouts: An Informational Guide, focusing on bicycle and pedestrian aspects.

One obstacle to their broader application is that they are unfamiliar elements in many cities whose only traffic controls have historically been stop signs and signals. Especially with roundabouts, everyone is sure they've seen one, but often it's not the kind that your city is considering.

John Ciccarelli is an experienced evaluator of school pickup/dropoff areas, access routes for bicyclists and walkers, and school parking lot operations.
