Welcome to the Perth Area Travel Household Survey website!  This survey was launched in May 2018 and it will be conducted over four years. Households will be randomly selected and householders will be requested to participate in a survey about their travel behaviour. Ultimately, the insights will help to inform infrastructure investment decision-making by the State Government.   

Households have been selected from Perth up to Two Rocks in the north, Mandurah in the south and Midland in the east.   Each year, between 1500 and 2500 households will be selected, with a total of approximately 7000 households expected to participate over the four years.

How does the survey work? 

1.     Households will be randomly selected to participate in the household survey.

2.     Householders will receive mailed notification that their household has been selected. 

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

4.     Once the householder consents to participation, the Ipsos representative will provide each householder a GPS device to carry for five days.

5.     In addition to receiving a GPS device to carry, householders will be interviewed at their place of residence by Ipsos about one of the travel days. This process aims to clarify any unclear travel information.  

6.     The Ipsos interviewer will collect the GPS device and paper surveys after five days.  

7.     Main Roads uses the data to support infrastructure investment decision-making.

8.     Main Roads will analyse travel patterns in the data to help inform decisions about infrastructure investment. 

9.     Information will be posted about travel patterns to this website. For an example of how travel patterns will be posted on the website, see the Victorian Integrated Survey of Travel and Activity.  

Note: Personally identifiable information about individual householders will be removed before the data is supplied to Main Roads.  Ipsos and its representatives act according to their obligations under the Privacy Act (1988) and the National Privacy Principles.

Industry innovation

Travel surveys are conducted all over the world, including across Australia.

Surveys have predominantly been conducted by paper or online, where participants have relied on their memories to record travel trips. As new technologies have become available, new ways of conducting travel surveys have been tested.  The research shows that Apps continue to be unreliable at present for the purposes of infrastructure investment; however, dedicated GPS devices have proven to be more reliable and therefore earned the interest from the industry.

GPS devices are currently being tested further in this survey. The industry will be interested in this project, as the successes are likely to be adopted for travel surveys worldwide.

​Transport Modelling

Information collected from the community will allow the State Government to update its strategic transport models used by the Transport Portfolio, and create a new, integrated Perth Transport Model. These models inform strategic transport planning, infrastructure and investment decision-making and are summarised below:
​Managed by​
Strategic Transport Evaluation Model (STEM)​

​Department of Transport

​Model strategic level transport planning scenarios and public transport demand.​
​Regional Operations Model 24 (ROM24) ​Main RoadsDetailed road planning scenario modelling and shorter term road network operational scenarios​.

​​​The Transport Portfolio

The Western Australian Transport Portfolio consists of the three agencies; the Department of Transport, Main Roads WA and the Public Transport Authority. Since 2010, these agencies have worked together to enhance the coordination of operations and develop unified policies and regulatory functions. These agencies have different responsibilities but together strive to provide world-class outcomes for its customers through integrated transport systems and services.
