CityCyclingEdinburgh was launched on the 27th of October 2009 as "an experiment".
IT’S TRUE!

Well done to ALL posters
It soon became useful and entertaining. There are regular posters, people who add useful info occasionally and plenty more who drop by to watch. That's fine. If you want to add news/comments it's easy to register and become a member.
RULES No personal insults. No swearing.
from BBC website:"Road pollution is more than twice as deadly as traffic accidents, according to a study of UK air quality.
The analysis appears in Environmental Science and Technology, carried out by Steve Yim and Steven Barrett, pollution experts from MIT in Massachusetts"
From the abstract (which is all you'll get on line)
We estimate the uncertainty in premature mortality calculations at −80% to +50%
Roughly translated: we're guessing. Note that the uncertainty is itself an estimate. They're guessing at how accurate their guess is. Really, I despair for, well, all of it.
So the actual guessed figure is possibly somewhere between 1,000 and 7,500 maybe?
Depends how accurate the guess is. Could be anywhere between -i and a squidillion.
More info is available on-line from "Electronic Supporting Information files ...available without a subscription to ACS Web Editions."
The estimate of how much there is of some of the main pollutants ranges from -20% to +30%. Add in how the weather disperses or concentrates or otherwise affects it, how different pollutants combine with each other (even sea salt), and then guess what the health effects are. So to get even within -80% to +50% for the range for possible early deaths might be optimistic. But the data and basis for the guesses is out there and something to build upon/improve to help decide the relative benefits of encouraging various forms of transport and power sources. The main conclusion I'd draw is that driving has more adverse effects than are obvious.
