Via Duncan’s City Ride:
The 2010 Toronto Cycling Map includes a brief description of bike boxes, a piece of infrastructure soon to be seen on Toronto streets.
Bike boxes will soon be installed at several intersections on Harbord and College. They allow cyclists to move to the head of waiting traffic, giving them priority for making left turns. Intersections with bike boxes will also restrict right turns on red lights (a safety feature I feel ALL Toronto/Ontario intersections should have) for both drivers and cyclists.
