Agree on 9th as I said. There should have been a cycle track there from the beginning.
No doubt bicycles have increased on Stephen Ave, but I wouldn't hold much faith in estimates prior to the automatic counters that went in as part of the cycletrack implementation. The vast majority of all traffic counts in Calgary's history didn't bother counting pedestrians, let alone bicycles prior to about 2010. Just because bicycles and pedestrians weren't counted doesn't mean they aren't there.
Near misses are rarely reported or tracked, so it's all anecdotal - but I find it extremely hard to believe that 810 bicycles a day are a bigger issue in causing near-misses and pedestrian injuries than however many vehicles drive down Stephen daily. Take this data with a grain of salt, but the only two accidents I can find online in recent years on Stephen are car-vs-pedestrian.
