“Metro Vancouver air quality suffers as driving increases”
The headline comes from a disturbing story in yesterday’s Vancouver Sun (paywalled)
I think many of us had been under the impression that driving was probably declining, since that was widely reported from US sources. It now seems that in this region we are not only driving more but in larger vehicles.
The proportion of small cars in Metro Vancouver has declined, to roughly 32 per cent of all vehicles in 2013 from 38 per cent in 2007. In contrast, the proportion of SUVs has risen to 22 per cent from 15 per cent over the same period and the share of large cars has increased to 20 per cent from 18 per cent.
At the same time, the study found the average number of kilometres driven by passenger vehicles fell by almost five per cent from 2007 to the first quarter of 2012, but that number has risen just over two per cent between 2012 and 2014.
Some of that might be attributable to the shifting around of transit service, which saw low ridership routes lose out to overcrowded routes – which also hit the outer, more car dependent suburbs harder than the region’s core.
The report can be found at autostat.ca which belongs to Pacific Analytics Inc.
The report is twenty three pages and is available as a pdf to download. There are some very notable omissions. No authors are credited. While there are plenty of graphs there are no tables, and no sources of data are cited other than Pacific Analytics model. For example, there is a very detailed analysis of vehicle types and some interesting, and quite remarkable data on vehicle kilometres travelled. But no source is cited for either. By implication the vehicle analysis would seem to come from ICBC, but I have no idea who has the data on vehicle kilometres travelled in the region by quarter, for every year.
So I called Jim Johnson, who is the sole proprietor of Pacific Analytics. He has given me permission to host the report here (link at bottom of article). The source of the vehicle data is a combination of data from AirCare (which of course will no longer be available) and the autorepair industry. A full description of the dataset is available at autostat.ca
Sinoski’s article tries to paint a relationship to the way Translink has been adjusting service. It does seem likely that in areas where transit was not a very good option (with the exception of the #555 bus along Highway #1 which enables people to avoid the Port Mann toll, and West Coast Express) and service has been cut, that driving would increase. The drop in gas prices would also have both reduced that disincentive to drive and the deterrent to buying a bigger vehicle. But while the auto manufacturing industry may have been turning its mind to more fuel efficient models, consumers seem to be buying the cars/trucks they want rather than the those that might burn less fossil fuel.
