Hey guys,
I could use some help - some dude going by chemical engineer(but never in the name field) is trying to claim it would be better if the people that took diesel buses would drive instead(at least with respect to toxins and GHG) on a Georgia Straight article -
http://www.straight.com/node/344939. "Migzy" is me. Feel free to "agree" my comments and disagree his, and/or add helpful comments.

In any case, I have disputed his every statement but he somehow is claiming I am helping his cause. Yes I know he is a "troll" but it would at least be good to have others agree with me(even if just on this thread)
To try and make his numbers work, he is also is somehow trying to say that 100,000 people would translate into 70,000 cars. I posted this in reply(needs GS mod approval before goes live) to show that doesn't make sense:

Let’s say out of 100,000 people, 50,000 drove alone. That leaves 50,000 to pack into 20,000 cars or 2.5 people/car. But 50% of people carpool, really? Even if we said 60,000 drove alone, that leaves 40,000 to pack into 10,000 cars of 4 people/car. Even 40% of people carpooling seems extreme and so does packing 4 to a car.

Some things I can't find(and please provide link if you have it), and I'll probably email translink if no-one has it, as now I am curious:
- the mpg(US gallon please) of translink's diesel buses(% of total service km would be ok as I know how much they spent on diesel in 2009 - $42 million and can approximate using $0.75/L)
- % of total service hours that are diesel
- where are monthly passes/etc counted as boardings? I'm guessing total boardings, not revenue boardings, as revenue boardings seem to be where people bought a new ticket. It would be good to know as there were an avg 160,000 passes bought per month in 2009. And a 342,000 daily boarding difference between revenue and total boardings. But if passes are non-revenue boardings, and assuming 2 boardings/day, that only leaves 22,000 for people that board more than 2x/day.
PS: Yes, once my GS comment goes live I know I made a mistake on the diesel costs and said they were 24.5 million, not the actual 42 million. In any case I doubt he will call me on it, as he apparently can't do math(even with a supposed Masters in Chemical engineering).
PPS: The translink annual reports for 2009 including the Statutory report, are treasure troves of info
cheers
