Heather Campbell comments on her summer scholarship research:
During
the summer of 2014-2015 I received a Summer Research Scholarship with Victoria University
of Wellington (VUW) and Greater Wellington Regional Council (GWRC) to explore
the GWRC’s 1988 and 2001 Household Travel Survey datasets.
The
main aim of this project was to explore changes in travel patterns in the
Wellington region between 1988 and 2001, by identifying statistical patterns
and producing map visualisations of these patterns. An additional aim of this project was to
integrate this Household Travel Survey (HTS) data into the Institute for the
Study of Competition and Regulation’s Wellington Spatial Econometric
Transportation (W-SET) model. Currently
based on the Ministry of Transport HTS, W-SET models residential choice, car
ownership and commute mode decisions within Greater Wellington.
The
GWRC HTS datasets are based on surveys of residents within the Greater
Wellington region about their trip making behaviour. The data consists of
information about each participant in the survey and the trips they made over
the survey period. Using these datasets
I compared travel patterns between 1988 and 2001, with a focus on commuting
patterns. In particular, I compared
changes in modal choices, car sharing patterns, vehicle ownership, time trips
are made, trips per person and commute times and distances (using network
analysis). These patterns were also
compared with data from the Ministry of Transport HTS for years 2003/04 and
2009/10. By using statistical tests and
producing visualisations of these patterns, many interesting changes in travel patterns
within the Wellington region were able to be explored – in terms of both
overall patterns and spatial patterns.
Heather's project was supervised by Mairead de Roiste and Toby Daglish. The industry advisor for the project was Nick Sargent.
