Layout of Roundabout and Miniroundabouts.

Hello all,

I'm designing the roundabout's now and since I'm new to this Can u please provide me some material for setting out the layout of Roundabout's and Mini Roundabout's. If possible can u please record the screen and send me the video file while u work on it. FYI I ill be using MX ss2 for the furthur Design process.

******** I dont want to use the civil geometry's Roundabout since I'm not comfortable with it.

Thanks and regards, Jayanth.M
