Key Design Features - Making it work for the Neighborhood

Key design features of the roundabout include:

• The grade entering the roundabout at Conrad Hill has been modified improving sight distances and creating a slightly flatter landing.
• It will reduce the frequency and severity of crashes compared to a 4-way stop controlled intersection. This is a result of slower speeds and fewer conflict points. For example, it will virtually eliminate T-bone style crashes because of its shape and one way traffic flow. Drivers simply slow down, look to their left, and merge into the roundabout.
• The design improves sight distances (ability to easily see on-coming cars to avoid colliding with them) on all approaches to the intersection.
• The design of the roundabout slows vehicles down to 20 to 25 MPH.
• Pedestrian crossings are improved. Traffic is slower and pedestrians only have to watch for one direction of traffic at a time. Raised median islands provide a refuge area for pedestrians to wait between the travel lanes.
• It has been designed to accommodate school buses and other large vehicles.
