Updates to transport trends – June 2015

Wed 10 June, 2015

I’ve recently updated three posts on this blog to include the latest available data. Here is a short summary.

Transport greenhouse gas emissions

Australian domestic transport emissions have continued to rise and is now the sector with the biggest percentage growth since 1990. Domestic aviation emissions have tripled since 1990. Car emissions per kilometre were improving until 2007, but we appear to have gone backwards since then.

Melbourne urban sprawl and consolidation

Outer growth areas of Melbourne now account for around 43% of population growth, but urban consolidation in the inner suburbs continues to exceed projections.

Are Australian cities becoming denser?

This fully revised post looks at calculating population-weighted density using a new population grid for Australia, which finally allows for an internationally comparable measure of city density. I’ve also taken a look at some smaller Australian cities. The data suggests Sydney, Melbourne and Perth have been densifying fastest in more recent years.

Updates to transport trends

Mon 29 July, 2013

For those not following this blog on twitter, I’ve updated a couple of posts with more recent data.

Public transport patronage trends in Australasian cities

I’ve updated this post with data for the 2011-12 financial year, which shows Perth, Melbourne and Auckland continuing to post strong patronage growth.

Sorry about the delay getting this out. I will try to update this post again in a few months time when 2012-13 patronage data is available for most cities.


Trends in Melbourne traffic

I’ve updated my post with the latest VicRoads (and BITRE) data published on Melbourne’s traffic.

While VicRoads have revised up their estimates of total traffic volumes on Melbourne’s arterial roads and freeways, the comparison with public transport patronage growth is still quite stark:

Updated public transport patronage trends

Mon 14 November, 2011

Just a quick note to let you know of an updated post on public transport patronage trends. I’ve got almost all 2010-11 data for Australian and now New Zealand cities.

Patronage is growing strongly in Perth, Melbourne and Auckland. South East Queensland has possibly stalled, although issues in patronage estimation methodology may be masking underlying growth. Adelaide and Wellington are showing more modest growth, while Sydney, Canberra and Hobart continue to be laggards. Christchurch patronage unfortunately collapsed following the terrible earthquake.

For all the details, as well as some 110 year trends in Australian public transport patronage, read the updated post.

In other news, this blog is now available at the easier to remember address chartingtransport.com and there is a new public twitter stream if you want to track updates that way.

Updates on transport trends (April 2011)

Sat 30 April, 2011

Several of my blog posts are about trends in transport data. Rather than create new posts when new data becomes available, I’m updating existing posts. But these won’t appear in your email subscriptions or RSS feeds.

So this post is a guide to five posts I updated over April 2011, with a highlight from each.

Evidence of mode shift in Australian cities (BITRE data)

BITRE have published a 2011 statistics yearbook, and there’s evidence of continued public transport mode shift in 2008-09 in Melbourne, Brisbane, Sydney, Perth, but not in Canberra or Adelaide.

Trends in transport greenhouse gas emissions

New national emissions data has been published showing transport emissions are increasing, particularly in freight and civil aviation, while car emissions are continuing to decline. I’ve done some new analysis that suggests vehicle efficiency only explains around 40% of the saved car emissions – the rest likely to be a product of travel behaviour change.

Peak oil

We haven’t yet seen peaking of global oil production (including non-conventionals), but both supply and prices are going up.

Melbourne urban sprawl and consolidation

Recent ABS population data show that there was a surge in urban sprawl in Melbourne in 2009-10, in both share of growth and numbers of new residents. There was also a lot less urban consolidation in 2009-10, and slower population growth overall (1500 new residents per week in 2009-10).

However, post June 2010  dwelling approvals data suggests a slight decline in sprawl’s share of population growth.

Traffic volumes on Australian toll roads

There’s been a recent surge in traffic volumes on Citylink in Melbourne, following the completion of major upgrade works:

Recent updates of transport trend posts

Wed 3 November, 2010

I’ve updated four posts on transport trends with more recent data. They probably won’t appear in your feeds, so here are some links:

(I’m editing existing posts instead of creating new posts when I update data)

I’ve also created an index page of all posts to make them easier to find.
