The 2000 figure, from what I've read, references the number of cars per hour in a lane, not people. So 2000 pph is true, only if every single vehicle only has 1 person in it. But some of those vehicles are buses. So, 1 direction on 104 ave can have 4000 vehicles/hour pass by. Today, how many buses go past a stop in an hour, during peak times? Now we are talking significantly more people per hour when you consider mixed use traffic.
That said, I do agree. 1 lane dedicated to rapid transit can carry transport more people than 1 lane of general traffic. Operative word being
can
What I'm arguing is that in this specific situation, on 104 ave, taking a lane from general traffic, and converting it to transit only, would do more harm that good.
According to Translink, peak demand during peak hours in 2041, on the 104 Ave section will be 1800 pphpd.

-pg 16.
The capacity of LRT on 104ave is 6500 pphpd. Seems like overkill.
Sticking with regular buses under the "Best Bus" plan gives you a capacity of 4000 pphpd. Even going with the business as usual plan provides a capacity of 1700 pphpd (more than peak demand under the best case). 104 ave is actually the only corridor where in every alternative, expected load does not exceed capacity.
Going with RRT 1 plan (Skytrain on Fraser and NO rapid bus) leaves the load on 104 Ave at 1000 pphbd; but jacks up load on Fraser to 6800. 6800 is actually higher than RRT1a's load of 6600, because without rapid transit on 104 ave, people from the Guildford area will change their travel pattern to ride Skytrain, now to their south.
Lets compare LRT1 (LRT on Fraser and 104) vs RRT1 (RRT on Fraser, regular bus on 104) ignoring ridership on King George.
LRT1:
- 104 Ave (LRT): 1800 pphpd
- Fraser (LRT): 4300 pphpd
- Combined: 6100 pphpd
RRT1:
- 104 Ave (shit bus): 1000 pphpd
- Fraser (skytrain): 6800 pphpd
- Combined: 7800 pphpd
Leaving 104 ave as is and building Skytrain nets an extra 1700 pphpd over building LRT.
People will find a way to the Skytrain, it's what has happened in every other city in the lowermainland.
So really?
What are we losing by not having rapid transit in dedicated lanes on 104 Ave?
No direct rapid transit access hasn't dampened the communities of Kerrisdale, Edmonds, or Royal City Center. Why does Guildford need a spur line straight to it? People all over the lower mainland have found a way to easily get to the nearest Skytrain station.
Is there any benefit at all to spending that money on 104 vs using it to build Skytrain instead?

With respect to 'lost man hours of all the other people stuck in traffic'. Most of those manhours are fake, and when faced with constraints on road capacity people adjust their habits accordingly. Those manhours mostly pay zero dollars, and society should spend no more effort in alleviating them then they spend on reducing wait times at Tim Hortons ('think of the manhours!'). For the people who *are* losing man hours on the road, professional drivers, encouraging more people to drive their private cars in general is the problem for them.

That is completely not true.
If time spent traveling has zero subjective value, then why spend any money to alleviate any long commutes? Even transit ones? Why didn't we just leave all the horse and buggy trails as they were? People would find a way to deal with it after all.
What? There's a river here? No need to build a bridge, the people on the other side are on that side for a reason.
And the time people wait in line at Tim Hortons does have a value. You really don't think Tim's has done studies and actually determined exactly how much they lose depending on how long the line is? They used to not take debit cards because they calculated they would lose more money from people getting upset at how long the line was vs turning away debit sales.
And I can't count how many times I've walked past a Tim Hortons and thought I would love a donut, walk in, see the line, and walk right out. My time does have value.
I worked in a retail chain and they had a study done to show how much they lose based on how long it takes for employees to say "hello" to a customer when they first walk in the door (if you wait longer than 30 seconds you probably lost a sale). Time is important.
In one post, your all time is money; now you are time is bullshit. Which is it?
