Place holder thread for Monday 23 October 2017

ABS Method of Travel to Work data is being released next Monday.

The key eight numbers of interest are: percentage of cyclists who are female for each of the eight capital cities.

This is only measured systematically every five years. The closest figure that's being measured is in the Australian Cycling Participation Survey ("While bicycle ownership has remained steady in comparison to the 2011 National Cycling Participation Survey, there has been a statistically significant decrease in the level of cycling participation in Australia between 2011 and 2017."). I think this is supposed to be one of the KPIs for Queensland's Cycling Strategy. gives a history of the numbers.

In the 2006 and 2011 Census, this percentage in Brisbane was the lowest of the eight capital cities.

I think Brisbane and Sydney will still be down the bottom, the question is which order will they be in?

The major differences are:

- Sydney has gone through Transport Minister Duncan Gay and Bernard Carlon is still "Executive Director for Centre of Road Safety"; together they've done their best to get cyclists off the road in the name of "safety" (implied message: "get a car")... there was continuous talk of licensing and registration, and massive increases in fines

- Brisbane has had the 2013 cycling inquiry which was supposed to make some changes, and now has CityCycle (rollout complete April 2012)

No change in BNE? It shows the lack of females cycling.


"Cheaper petrol, low fuel taxes and our continued investments in freeways, toll roads and intelligent transport systems to make roads better and better for car movements just makes driving irresistible."

Meanwhile, London is to introduce a pollution tax on older cars on top of the congestion charge.  Linky here

Forgive my obtuseness, but is there some sort of guide. I assume that each blue dot when you zoom in represents a certain number of cycle commuters, and those dots resolve into bigger dots when you zoom out, if there's a concentration of cyclists.

It's interesting that the North seems generally to be sparser for riding to work than the south. Is the big dot that stands out in the Enoggera area the military base, I wonder?

TableBuilder data supposed to be coming out this month, then more interesting analysis will be possible

Unless I've misunderstood that - it's still not in Tablebuilder Basic or Guest, so ABS missed that deadline. Still waiting...

ABS reply

The place of work data for the 2016 Census has been temporarily removed from the ABS website so an issue can be corrected. There was a discrepancy in the process used to transform detailed workplace location information into data suitable for output. The ABS will release the updated information in TableBuilder on December 2. The Working Population Profiles will be updated on December 13.

Finally got some time to write some R - and received a suggestion to plot 2006, 2011, 2016 by distance from centre of Brisbane. I did a CBD BUG Facebook post about it, reproduced here.

The five-yearly ABS Census provides the most complete picture of commuter transport available, through the "Method of Travel to Work" question.

If we plot the Brisbane data for trips made by bike only, and cycling trips made by females, and then further break this down by distance and bearing from the centre of Brisbane, the time series data over 2006, 2011 and 2016 is fascinating.

During this time, the CityCycle scheme has been introduced while the Riverwalk was available in 2006 and 2016, but not 2011. In the CityCycle area (CBD and surrounds), 1.3% of the city area contains 6.8% of the off-road bikeway length.

We see that although Brisbane City Council has missed their 2016 target of 2.5% of _all_ trips by cycling, at a distance of 1-2 km from the centre, 31% of bike commuters are female, and this is generally increasing at each distance and through each census (except in North Brisbane).

At a distance of 2-3 km out, 5.2% of commutes are made by bike. Looking at the directions, the Riverwalk rebuild made a big difference to bike commuting from the near east, while further east across the river (Bulimba, Morningside) is difficult because of no Green bridge for Bulimba/Teneriffe; few choose to brave Wynnum Road.

The strongest visual though is the North Brisbane charts. While females make up over 25% of all cycling commuters 5 km or less from the centre from the west, east and south, they make up only 15% from the north. At any distance only about 3-4% of north side residents choose bike commuting. This is due to the poor infrastructure in this direction - starting with the Grammar shared path, unlit after sunset; the "Albion-Wooloowin Death Corridor" of Dickson St; the lack of dedicated bike lanes on Kedron Brook Road; and so on.

The graphs indicate that bike commuting levels are clearly correlated with infrastructure separate from motor traffic. These levels will not be increased by "confidence courses". Finally the commuting rates in the centre itself indicate the need for a #minimumgrid in the CBD so that all people can ride there regardless of their level of "confidence".
