Thanks to Iain Campbell for this great infographic "Two Wheeled Traffic, or why bike lanes work"! It shows the bike traffic volume relative to the size of the road. Thus a street like St. George has only two car lanes but carries many more cyclists than nearby Queen's Park/University with its 8 lanes. Iain's data came from the City's 2010 Bike Cordon Count, which counted bike traffic into and out of downtown over 24 hours.
Iain's infographic provides a strong visual of how bike lanes are a much stronger magnet for cyclists than the importance of a road for car traffic. It strongly suggests that people will go out of their way to travel on a more comfortable, less stressful street with bike lanes. This is why I believe that separated bike lanes on Richmond and/or Adelaide will be a big draw for people of all ages, shapes and sizes.
