Challenge: Put together a preliminary design layout of a roundabout for the intersection of one-way streets being converted to two-way streets. Keep all lanes at 12′ widths, avoid right-of-way conflicts by keeping the design within the current curb-and-gutter boundaries.
Done before lunch. Who at your firm takes these challenges with this kind of excitement? Click through for full resolution graphics.
That’s a challenging location with the restrictions on space.
To me the biggest challenge is making a design that results in lower speeds. How to you get the (assuming north is at the top) southwest bound to westbound traffic to slow down? Similarly, how do you get the eastbound to eastbound traffic to slow down? There does not seem to be enough space to implement curved approaches to the roundabout. The resulting design, with such limited space results in high speed entry and exit in the above mentioned movements.
This is why roundabouts are generally discouraged for locations with such a skew angle (notwithstanding major redesign to get the approaches closer to 90 degrees from each other).
Cheers!
