Given the ridership figures for various bus routes, is there any logical reason for building the Evergreen line before extending the Millenium line west to UBC?
The 97B line doesn't even make the top 20 routes.
Ridership on a transit system depends on density of population and density of jobs. Do the following experiment: take a drive or the bus between Broadway/Commercial station and UBC on Broadway/10th Ave and compare that to a trip between Lougheed Mall and Coquitlam Mall on North Road, Clarke, and Barnet Highway. Look for population density, job density, places people go daily. Other than 2 or 3 patches of buildings along the route in Coquitlam/Port Moody, there is little or no density.
This is an example of a politically motivated decision that wastes money and limits resources for where they are actually needed.
I have seen a prediction of about 25000 per day riding the Evergreen line when it initially opens. The line is about 11km long, which is about 7 miles. Hence, there will be about 3,500 riders per mile. The figure for the Expo/Millenium line is between 8,000 and 9,000. The Canada line is about 20km, which 12.5 miles. Ridership is reported to be close to be 90,000 - 100,000 per day, which is about 7000 - 8000 mile.
I use the riders per mile figure, because it makes easy comparison to figures for other North American systems given in Wikipedia:

http://en.wikipedia.org/wiki/List_of_United_States_light_rail_systems_by_ridership
Even if the Evergreen line hits 35,000 riders per day on opening day, it will still have only 5000 riders per mile.
The Millenium line extension using Skytrain to UBC is about 12km, which is about 7.5 miles. It will easily reach the 8 - 9000 riders per mile per day average for the Expo/Millenium line on opening day given the existing ridership on the 9, 17, 99 buses which run along the route to UBC.
