In Delaware County, the Ohio Department of Transportation (ODOT) identified safety concerns at an existing 4-leg rural intersection and opted to replace it with a roundabout as the preferred countermeasure. Due to the existing skew of the intersection and property locations of adjacent parcels, ODOT studied a standard roundabout design, along with an elliptical roundabout and a peanut-shaped roundabout. 

Design was completed using Bentley® Solutions’ OpenRoads software, in which 3D models and a driving simulation were created to more accurately display the roundabout concepts to township officials. The peanut-shaped alternative was chosen for its ability to remain on non-residential land, greatly reducing impacts to nearby residents while implementing the preferred intersection improvements.

Attendees will develop a more detailed understanding of:

  • The benefits of non-standard roundabout designs
  • The process used to cost-effectively and efficiently develop alternatives 
  • Effectively communicating roundabout concepts for consensus among key stakeholders
