I'd like to add my 2cents to this discussion.
I think that the Broadway line to UBC should be the highest priority among all rapid transit lines
(1) Broadway already has extremely strong ridership. I believe that the the 9 has the highest ridership among all electric trolley route. The 99 has the highest ridership among ALL translink bus routes.
(2) A rapid transit line to UBC benefits people from the entire region. It is not simply people from Vancouver who will be using this line. People from all over the region take transit to UBC daily. I am will to make a large bet that of those who transfer from the Millenium and Expo lines to the 99 bus, more than 50% live outside Vancouver.
(3) If population density along Broadway is such a concern, then why build a rapid transit line in Coquitlam or Surrey at all? Vancouver has a population of about 600,000 and a density of around 14000 per square mile. Surrey has a population of about 400,000+ and a population density of about 3,500 per square mile. Even if you exclude the population of downtown Vancouver (about 80000), the density in Vancouver is still around 12000 per square mile.
The area along Broadway from about Main to Granville has a large number of jobs and has population density. The density tails off as one approaches UBC, but UBC is the 2nd or 3rd most popular transit destination in the whole system. (Central Broadway between Granville and Main is either 2nd or 3rd more most popular as well.)
Can someone tell me what are the destinations in Surrey where large numbers from outside the region travel for jobs or school?
In last year's auditor general's report on structural deficit at Translink, the following was written (page 75):
The majority of the $130 million structural deficit faced by Translink is a result of factors other than the Canada Line, such as the increase in the operational cost of the bus fleet, particularly into lower ridership, geographically spase areas.
geographically sparse = low density.

(4) In one of the articles it is stated by a Surrey councillor that Vancouver is a place where one doesn't need a car, but one does it one in Surrey. OF COURSE you idiot. There isn't some conspiracy against Surrey. Vancouver has 4 times the population density than Surrey! More density, more potential ridership, more potenial revenue from fares, less subsidy to run a bus/rapid transit service, better chance that a transit service can succeed.
(5) Extending the skytrain to Surrey and/or Coquitlam is going to add more strain to bottleneck that is Broadway-Commercial station and the transfer to the 9 and 99 bus.
