Welcome to the Transport Data Surveys website. This website covers the provision of the Household Travel Survey, Stated Preference Survey and Commercial Vehicles Survey. Each survey is conducted across the Perth and Peel regions in Western Australia. 


Perth Area Travel Household Survey

The household  survey was launched in May 2018 following the development and testing of two pilots, and is expected to be conducted over four years.

How does this survey work? 

Householders are asked to participate in a voluntary survey about the way they use the transport network. Insights from travel behaviour are collated, and the data is analyzed to help inform infrastructure investment decision-making.

The step-by-step process is as follows:

1.     Households are randomly selected across the Perth and Peel regions.

2.     Householders will receive mailed notification explaining the voluntary survey. 

3.     A representative from Ipsos Social Research (Ipsos) will visit the household to explain the survey participation process.

4.     If the householder consents to participation, the Ipsos representative will provide GPS devices for householders (aged 12 and above) to carry for five days.

5.     Householders will be interviewed by the Ipsos representative about one of those travel days to clarify information.   

6.     The Ipsos representative will collect the GPS devices.  

7.     Travel information collected within the GPS is downloaded at a later date and collated with other householder travel information, and this collective entity of data is provided to us for analysis about the way in which the transport network is used. Personal and sensitive information is de-identified prior to Ipsos dispatching the entity of data so that householder privacy is protected. See the Privacy Policy for further information.

8.    Travel behaviour insights will be available to the public. For an example of public information about travel patterns, see the Victorian Integrated Survey of Travel and Activity .  

Note: Ipsos complies with the Privacy Act (1988) and the National Privacy Principles.

Commercial Vehicles Survey

Accurate freight movement information is essential for freight route planning and efficient movement of freight across the Perth metropolitan transport network. 

In June 2019, Ipsos was awarded the tender to support us in our objective to collect information about the way in which commercial vehicles utilise the network. The survey is expected to be conducted over two years.

Progress about the survey will be posted on this site.

Industry innovation

Travel surveys are conducted throughout Australia and across the globe.

Surveys have predominantly been conducted by paper or online, where participants have relied on their memories to record trips.  As new technologies have emerged, new ways of conducting travel surveys have been tested.  The research reveals that mobile phone applications are unreliable at present for the purposes of infrastructure investment decision-making; however, dedicated GPS devices have proven to be more reliable, provide greater privacy, and therefore earned interest from the industry.

We are currently using GPS devices in the Western Australian household survey.  The industry will be interested to review the success of this new way of recording transport network consumption, and the successes are likely to be adopted for future travel surveys worldwide.



As a portfolio, Department of Transport, Main Roads and the Public Transport Authority are responsible for providing integrated transport solutions and services.

A review of transport modelling across the State Government highlighted the need for an integrated transport model.  The Perth Transport Model  addresses the metropolitan transport modelling  requirements, for short-term network operational needs and strategic planning.  The success of the model relies upon the availability of current and accurate data sourced from key surveys.
