A Cycle Track can move many more people per hour in one lane, than two traffic lanes with cars can. If we build bike lanes in a congested city - people on bikes will come ... thus reducing the number of people using their cars. Adding cycling infrastructure will reduce the congestion that we are all experiencing on Toronto's arterial roadways - at all hours of the business day it seems these days.
Using this "StreetMix" application I can visualize Carlaw Ave in different configurations based on a known Roadway Footprint measurement. For this test I've chosen a 13 metre wide footprint (property line to property line).
Here's Carlaw Avenue as it exists now (assuming 13m) at off-peak hours: two traffic lanes; two parking lanes; and very narrow sidewalks (a function of the Industrial 'built-form' - the architectural and cultural history of the area).
Now there are just two car lanes, one northbound and one southbound - wider sidewalks, and a "Cycle Track" (a two-way Bike Lane) on the West side of Carlaw. I also added a separation island for the Cycle Track, and made the sidewalk as wide as I could...
Below I narrowed the Cycle Track and the separation device so it equals the 2.8 metre width of the car lanes. (total car lanes: 5.6 metres). I've widened the sidewalks as much as possible once again.
That feels better. :)
