<p>In response to a comment from  KitKat, please see below:</p><br><p>There has been significant traffic modeling done at these intersections and for the surrounding areas.  The designs shown a combination of single and double entries, and all single exits.  We have only used double configurations where necessary to accommodate traffic. The geometry of the intersections is also designed to keep drives at slow speeds and we are spending significant time on the signage and pavement markings to give all users the best direction.</p> <p>On double lane entries, the signage and pavement markings will guide drivers to use the correct lane before entering the roundabout. Once in their lane of choice, drivers should not switch lanes within the roundabout. Street name signs will also be posted at each exit to give drivers confirmation of their destination.</p> <p> </p> <p> </p>
