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)

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: Data scales

Area unit level Meshblock level Parcel level

Traffic zones Census data Houses and building data

WLUTE: Stage 1, Data collection and cleaning

Initial approach to data collection

Issues that arose1. 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

Local councils and collect property and parcel databases along with roading/parking

Use open source data (eg LINZ, Koordinates)

Government departments

WLUTE: Stage 1, Data collection and cleaning

So now using QV property data linked to parcel data

CURRENT WORKCleaning and developing road network filesLinking QV dataset with parcel ID datasetGrouping and simplifying QV datasetDetermining landuse split in parent-child arrangementsMapping parking
