Let's turn the intersection into an all-ways crosswalk. Also called a 'pedestrian scramble' it enables people to cross the intersection in every direction at the same time.
What's more, for that brief moment the intersection becomes a plaza that can be 'occupied' until the light changes.
To accomplish this, the surfacing could be changed to allow safe passage across the tracks and this opportunity could be used to think of the intersection as a canvas to emboss colors, patterns, images, directions to nearby landmarks, and other symbols such as the maple leaf.
