Thanks for clarifying that it was 39,000 on King only (the previous poster just said "the intersection"). It also has to be remembered that this data is from 1999 and traffic volumes have declined (Main at Dundurn has declined by 9.5%), so the actual volume now is likely to be closer to 35,000.

Note that the average volume for King West of Bay is much lower, 25000 per day, and one could also use this figure rather than the figure just at Dundurn. http://www.raisethehammer.org/article/17...

We are actually interested in weekday capacities (since that is when demand is heaviest), so we can estimate that (15)(70)/56 = 18750 HSR passengers + 2000 or so Go is about 20,000 bus passengers at that intersection each weekday compared with 35,000. Since there are four non-bus lanes, that is about (8750)(1.1) = 9625 car passengers/drivers per lane (assuming 1.1 people per car) compared with 20000 bus passengers. So the bus lane seems to be carrying as many people as two (or three using the "King West of Bay" data) regular lanes at this location. Not as many as all other lanes, but far more than necessary to justify its existence!
