Frequently Asked Questions

This survey is the only source of information on the day-to-day travel of people living in the Sydney Greater Metropolitan Area (GMA). This area covers Sydney and surrounds, including the Central Coast and Blue Mountains, and extends to the Hunter region in the north and Illawarra in the south.

The survey collects information about people's day-to-day travel, such as where they go, when they travel, purpose of the trip, modes of transport used, and costs associated with the trip. This is used to generate aggregated data on travel patterns of particular segments of the population.

The data you provide in the survey helps Transport for NSW understand the travel patterns in Sydney Greater Metropolitan Area and how they change over time. Understanding the community’s travel needs today can help us plan a better transport system for the future. 

We understand not all days are the same – so even if you do not travel on your assigned travel day, we would still appreciate your participation. While some people will make a lot of trips, it is just as important for us to know about those who don't travel much, or at all.

We are interested in all types of travel – cars, buses, trains, light rail, planes, taxi, ridesharing, trucks, motorbikes, bicycles and walking.

So, on your travel day, it does not matter whether:

• you do not go anywhere at all;
• you only leave the house once or twice; or
• you make lots of trips.

Please record what actually happened on your travel day, even if this is different to your typical daily routine.

Transport for NSW, the state government agency responsible for transport planning for whole of NSW is the owner of the survey and it is conducted by Ipsos on behalf of TfNSW.

The survey is undertaken through in home face-to-face interviews on pre-programmed tablet devices. Field staff from the survey company Ipsos, on behalf of TfNSW, will visit all selected households to explain the survey and they will organise a date and time that suits your household for the survey interviews to take place. 

The interviewers will leave a Memory Jogger for each member in your family – including children and senior citizens, if any. Your family will be assigned a specific Travel Day – please record all trips that you make on your Travel Day on the Memory Joggers provided. The interviewers will then return to complete the survey interview after your Travel Day.​​​​​

The information that is collected from households will be summarised statistically to describe a variety of travel patterns, which are also used to inform transport planning. For example, how many trips are made on average by different modes of transport in different areas, the average distances travelled for different purposes and by different modes, and the average travel times by different modes and for different purposes.

The survey is not compulsory, but most households appreciate the opportunity to provide participate and help us better understand travel patterns from a wider range of people. Without your participation, we will not have the necessary information we need to plan for a better transport system, so we sincerely appreciate your participation in the survey. 

All information collected during the survey is confidential and will remain confidential.

Transport for NSW is committed to protecting the privacy of your personal information in accordance with the Privacy and Personal Information Protection Act 1998 and the Health Records and Information Privacy Act 2002. 

Information collected from households is treated with absolute confidentiality, and is merged with information collected from other households, for analysis. No data that allows identification of survey participants will be released.

Households are selected based on their street addresses. The survey company selects street addresses through a randomisation process, from the Geocoded National Address File (G-NAF), which is a publicly available database of street addresses. Households residing at the selected addresses are sent a letter telling them about the survey and their selection. 

Since this is a travel survey, it will primarily collect travel related information for each household member. This will cover information such as:

• departure / arrival times for trips you made
• addresses of the locations you went to (these are needed to determine travel distances)
• what you did there (this helps us understand travel purpose such as work, education, recreation, etc.)
• how you travelled, i.e., car, walking, bus, train etc.

The interviewer will also collect generic information about yourself and other household members such as age, gender, work status, type of household, vehicles owned etc. This information helps us understand the demographics of the sample population so we can monitor that we are collecting data from all types of households in the population.  

Go to the next question “Why do you need details of everyone in my household?”

People of ages and demographics use the transport system – even children and senior citizens! Different people travel in different ways, even within the same household. So, everyone’s input matters, and is important for us to understand the complete picture of how people travel on a day-to-day basis.

This is why, in addition to asking about your travel, we also ask questions about age, gender, occupation, household type and income to make sure we have included all types of people and households in our sample. This information is then combined with those from all other households in the survey to give a complete picture of the day-to-day travel and activities of all people in the community.

The demographic composition of the survey sample is also compared with the results from the Census to ensure that our survey respondents are representative of the broader population.​​​​

While household members may have a general idea of regular travel that other members made on their Travel Day, they may not have all the specific details of the trips unless they travelled together throughout the day. For example, you may know that on the Travel Day your partner or spouse went to work and back but may not necessarily know if they stopped for a coffee on their way or about work meetings or other trips they may have made throughout the day. For this reason, it is best that we collect travel details from each household member individually as they are best placed to provide us accurate details. 

We know that travel patterns of households can be impacted by commitments around children in the family such as pick up or drop off trips to/from school or childcare, sporting and other academic or extra-curricular activities. 

HTS is currently the only reliable source of travel data for those under 18 years of age. This data is essential to gain a complete picture of travel patterns across different demographics to inform our planning decisions.

Each household is assigned a specific Travel Day by the survey team. This is done to make sure we can collect data for all days of the week across every area. Travel Days are assigned through a randomisation process and this ensures there is no bias in the day of week assigned to households. For this reason, we are unable to change or assign travel days on request.

Please report all travel on the specific travel day assigned to your household, even if you feel that day may not be a "normal" day for you (for example, if the trips taken on the assigned Travel Day are more than you would typically take or you didn't travel at all). By having each household report about their assigned Travel Day we can ensure a good average of all the travel days is obtained without any bias. 

We ask a number of questions about the vehicles in your household (including any company or government cars that are parked at your household on the night before your Travel Day) so that we can get an idea of how these vehicles are used. It is important to know what type of vehicles you are using so that we can then estimate things such as the fuel consumption and Greenhouse Gas emissions caused by daily travel patterns.

Individual’s transport needs are linked to where they work and the kind of work they do. The street address of your workplace is collected so we can accurately determine the distances people travel for work. Workplace addresses are converted into geospatial coordinates to calculate distances between work and other destinations and identify trip purposes (if required). We acknowledge that after COVID-19 you may only be working in the office on some days of the week, so if you travelled to work on your travel day, please provide us your work address so we can accurately determine your trip distance. 

School or childcare addresses are collected so we can accurately determine the distances people travel for education or childcare. 



School or childcare addresses are converted into geospatial coordinates to calculate distances between school and other destinations. 



This information is important to transport planning since travel for education is undertaken regularly and the data will help us determine the transport needs of school children and children who attend childcare. This information is also used to understand the distances that parents travel to pick/drop their children at their place of education/childcare.
