WILUTE: Wellington Integrated Land Use,
Transport & Environment model
Objective:
to establish a platform to evaluate individual transport & land use
policies and scenarios, with a particular focus on transport-related
environmental & public health effects.
Features:
•
Focus on integration (land use and transport; environment and health…)
•
Focus on co-benefits (environmental outcomes, health impacts) not modelled
elsewhere
•
Can complement other regional models (LTLUP,MASTER,TOPAZ2000)
1
WILUTE: 4 key questions (to date)
1.
How do current and future land use and transport policies
affect economic activities and property development in the
Wellington Region?
2.
How does the development of the transport and land use
system affect local air quality and public health in the region?
3.
Can new transport infrastructure (e.g. new LRT, new cycling
lanes) change the features of current transport modes and
promote green transportation?
4.
To what extent can transport pricing policies (e.g. car
parking, oil price) reduce transport emissions and achieve
public health co-benefits?

WLUTE: Stage 1, Data collection
and cleaning

Initial approach to data collection
Local councils and collect
property and parcel databases
along with roading/parking
Government
departments
Use open source data
(eg LINZ, Koordinates)

Issues that arose
Christchurch earthquake
2. Data was not consistent across councils in terms of detail and
recording methodology
3. Model would be limited to lowest common denominator

WLUTE: Stage 1, Data collection
and cleaning
So now using QV property data linked to
parcel data
CURRENT WORK
Cleaning and developing road network files
Linking QV dataset with parcel ID dataset
Grouping and simplifying QV dataset
Determining landuse split in parent-child
arrangements
Mapping parking
