Road design, safety and Vision Zero

[Bytor]

Here's a design for a Dutch-style turbo-roundabout layout for 4-lane arterial road and 2-lane neighbourhood collector street done with Ontario HTA compliant markings. 

Basically, the curblets prevent people from changing lanes once in the roundabout, but emergency vehicles can still easily mount them if need be.



I probably should Y-split the roads where they touch the circle to allow for a smoother transition into theroundabout instead of the sharp corners, but you get the picture.
