Identifying Frequent Stops with GTFS
Sometimes when I’m doing analysis I find myself needing to figure out
how many services each route (or stop/station) has in a week, or if a
location has frequent service.
-
nparty - comparing House and Senate
My original
goal with n-party-preferred analysis, back in 2016-2017, was to
apply One Nation’s 2016 Senate performance to state seats to get a good
idea of their between-seats variation. I could then apply state-level
aggregate polling numbers to estimate results in each seat.

Effective frequency calculator
If a station gets four trains per hour, that’s one every fifteen
minutes, right?

A Queensland state election predictor using the 2022 Senate results as a basis
The same non-uniform swing model, updated for 2024 with Senate data from 2022 rather than 2016.

Thoughts on Brisbane Metro
Brisbane’s busway network is a victim of its own success. The
“Metro” project, while misleadingly named, is what’s possible as an
incremental upgrade.
-
Modelling SA1-booth correspondences
Elections have geographic aspects: people live somewhere and
often your neighbours are similar to you socio-economically. Further,
both boundaries and polling places can differ across the three levels of
government, and they change over time.

SEQ Rail: the next decades
Cross River Rail will soon be completed.

Population and Transit Mapping
When designing a public transport system we have a number of goals.
We want to (equitably) provide as many people as possible with a basic
level of service. But in order to move the greatest number of people
(e.g. to substitute for as many car trips as possible) we want a network
design and resource that focuses service on a frequent grid-like
pattern.

Ferry extension up the Brisbane River
Something that comes up occasionally on comment sections that I see
is the idea of extending the CityCat upriver from UQ. I suspect it’s not
justifiable for journeys to (or past) the city but it might be
worthwhile for more local trips.

Three-Party-Preferred Graph Generator
As 3PP contests become more relevant, a need arises for analysis
tools.
-
Fluvial — a transit patronage visualiser
My local public transit authority, TransLink, releases origin-destination
patronage data.
-
Redistributions
I have authored two submissions to federal Redistribution
Committees.
-
Transit Maps
My favourite part of what graphic design I do is definitely the
transit maps I draw.

QLD state predictor from Senate 4PP - how'd it do?
Any predictor is not much good unless it's been tested.
-
A Queensland state election predictor using the 2016 Senate results as a basis
Following on from previous work projecting the 2016 Senate results onto the new Queensland state seats, I thought I might try a non-uniform swing model.
-
Queensland state projections from Federal Senate voting data
With the resurgence of One Nation, there's some need to model how they'd perform running all over Queensland in a state election.
-
Music Theory
I once gave an ‘Introduction to Music Theory’ talk, on behalf of one of my choirs.
-
MMP-OPV
When designing an parliamentary electoral system, there are two main
considerations. First, how are people represented at the local level?
Second, how are the people represented as a whole?

DMCA Bait with randomly generated 'music'
Do some music services really scan content for infringement or do
they just make a judgement call based on the metadata?
