THIS might be an idea that can be incorporated into the SGR redevelopment.
Basically it is a "scramble" of pedestrians crossing an intersection with all traffic stopped. They are given something like 30 seconds to cross the intersection in any direction. They've introduced these intersections in the U.S., Vancouver and Toronto (just to name a few).
SGR is already a pedestrian controlled road and this idea would further attract more people to walk there while dettering traffic. Since they are planning to tear up the road it would be easy to install, and it would go along with the "green" idea for the revamp. I'm not saying install at all the intersections along the road, only a two or three intersections (South Park, Dresdon and maybe Queen). I can say from personal experience that if this idea was to work anywheres in HRM, SGR would be the best testing street.
