Frequently Asked Questions
What is Open Data?
Open data is the idea that public information should be accessible, used, modified and shared by anyone for any purpose without restrictions. Open data should be both technically and legally open: technically open in that it is available and accessible to the community, and legally open in so far as there are appropriate licensing frameworks in place to facilitate its release, use and reuse by the community.
What is a dataset?
A dataset is a collection of related sets of information, which shows relationships between categories and variables. An example of a dataset is a table of all train stations in NSW, with a set of information about each station, such as platform numbers.
What is the difference between a dataset and a resource?
Datasets contain individual resources, as well as metadata. Metadata contains information about the dataset. Resources are the files within the dataset. A dataset may have multiple resources such as APIs, links or images.
What are APIs?
Application Programming Interfaces (APIs) are a set of rules and instructions for how software can interact with a dataset. APIs allow flexibility in how information within a dataset is accessed, typically so that users can select only a specific, relevant subset of the information. APIs are usually connected to datasets that are updated in real-time.
What type of data are TfNSW offering?
TfNSW offers a number of datasets and APIs for all public transport modes and roads. These include static timetable information, as well as live and real time information (feed data). If you have an idea of data that you think would be useful, let us know on the Forum.
The Open Data Program
Why is Transport for NSW opening its data?
Making more government data available to the community is a key commitment of the NSW Government, is a priority of the NSW Government ICT Strategy, and is a driver of the NSW digital economy. By providing data to the community, we can improve transparency and accountability, enable evidence-based policy decisions and provide a platform for innovation. TfNSW has provided open data since the launch of the TDX Program in 2009. TfNSW is committed to fostering innovation in the digital economy, and is excited to see the innovations and creations the community produce using our data.
Does the TDX program still exist?
The Open Data Program replaced the TDX Program in April 2016. The Open Data Program is providing access to a broader range of information than the TDX Program, including the provision of APIs.
Is Transport for NSW the only NSW Government agency opening its data?
The NSW Government has made a commitment to opening more data to the public and many NSW Government agencies have begun releasing open data. Examples include Family and Community Services, Property NSW and the Information and Privacy Commission. For a full list of NSW Government agencies providing data to the public, please visit data.nsw.gov.au Open data is not only a NSW initiative and is quickly becoming a priority for governments across the world, including Europe, North America and across Australia too! To find out more about our federal open data please visit data.gov.au.
What is the Open Data Hub and Developer Portal?
The Open Data Hub and Developer Portal is where you will find all publicly available TfNSW open data. It provides access to all APIs and datasets, as well as developer information to get you started and a Forum to contact us.
Who owns the Transport for NSW open data?
Most of the data published on the Open Data Hub is provided by Transport for NSW or other associated entities. Ownership is usually indicated for every dataset.
Using Transport for NSW data
What do I need to know before I start using TfNSW data?
What can I do with open data?
The possibilities for using TfNSW data are endless and already we have seen many innovative ideas! The data can be used to produce maps and reports, or used by policy makers and transport planners to gain insights, for analysis and informed decision making. Most commonly, the data is used to create transport apps, both for public transport modes and roads. You can check out some of the apps developed using TfNSW data in our showcase.
Is TfNSW data accurate?
We derive and directly source our data from operational systems within TfNSW. While we cannot guarantee the complete accuracy of the data, it is the best source of data for our transport services.
Is new data added to the Open Data Hub and Developer Portal?
We are constantly working to release new datasets and APIs. You can request data by emailing OpenDataProgram@transport.nsw.gov.au.
How is data containing private information protected?
TfNSW sets out to provide as much data as possible, and some datasets need to be cleansed before being released. This may be due to safety, commercial concerns or protecting the privacy of our customers. These datasets need to be identified, prioritised and made available in the appropriate format.
Can I host my own data or app on the Open Data Hub and Developer Portal?
No, the Open Data Hub and Developer Portal is designed to provide data for you to use and is not a hosting service.
Can I publish my own data to the Open Data Hub and Developer Portal?
Currently, only TfNSW can publish data to the Open Data Hub and Developer Portal.
Can I use my own API?
You can use your own API, but you will need to host your own API or use another host.
Do I need to have technical knowledge to access the Open Data Hub and Developer Portal?
The Open Data Hub and Developer Portal is accessible to anyone. While access to APIs is designed specifically for developers with technical knowledge, we also offer the ability to download datasets which requires no technical knowledge. Downloadable datasets are often used by researchers who are interested in TfNSW data. If you get stuck, the Forum is available to everyone. Through the Forum the community and TfNSW staff can assist with technical queries and general questions about the data.
What data formats are used?
Static type data is available in text formats, usually in a zip file. Feed data is available via APIs in specific formats. Check the Data Catalogue for more information.
Where are the code samples for the API Explorer?
The new Open Data Hub and Developer Portal, does not display code samples. A cURL command is provided to test your API details.
I’m using TfNSW data to create a product; is there any design or branding guidelines I need to follow?
The use of TfNSW data should not be seen as an endorsement, sponsorship and/or partnership and you should never brand your product in a way that states or implies this. Visit the Marketing page for full details of what you can and cannot use to brand your product.
Can I reuse or redistribute TfNSW data?
For any dataset or API with a Creative Commons by Attribution 4.0 licence, you may reuse and redistribute the data. Please check the licence for the data you are using.
How can I share Application credentials?
The creator of the application can share the API credentials (API key or OAuth credentials) with other users manually. There is no system functionality enabled to share apps or API credentials. **Please note:** you should never share your user credentials (username and password) with anyone.
How can I have my product featured on the Showcase?
You can request to have your product included on our Showcase by emailing OpenDataProgram@transport.nsw.gov.au with the following information: * An overview of your app or website * Features or services you offer * A high resolution logo * Screenshots of your app or website.
Why isn’t the API Explorer working for the Timetables Complete GTFS and TransXChange APIs?
The Timetables Complete GTFS and TransXChange APIs return large files, and is unlikely to work in the API Explorer (or when Explore API is selected in the Data Catalogue). You can download the zip files by selecting Download in the dataset. Should you wish to retrieve the files on a regular basis, you can use your API key to retrieve it programmatically.
What methods of authentication can I use for my apps?
We recommend using API Key authentication as it is simple and has fewer issues than the OAuth 2 authentication. If you are using OAuth 2 authentication you may continue to do so.
Why are there multiple records for the same ferry in the vehicle position feeds?
The GTFS-realtime ferry feed reports all current and future vehicle positions. This causes a "trail" of vehicles to appear while the ferry is moving. It's possible to filter out to only show the current trip's vehicle position. Use vehicle > id as the unique identifier. Since the ferry feed no longer reports vehicle positions once a trip has been completed, you can cross reference with the GTFS-static data to identify which trip begins the earliest (i.e. has the earlieststop_times.txt entry).
How often are real-time data feeds updated?
Sydney Trains GTFS and GTFS-R: Real time data is updated every 15 seconds, static data is updated once a day
Bus GTFS and GTFS-R: Real time data is updated every 15 seconds, static data is updated once a day
Ferries GTFS and GTFS-R: Real time data is updated every 15 seconds, static data is updated once a day
Light Rail GTFS and GTFS-R: Real time data is updated every 15 seconds, static data is updated once a day
Rural and Regional GTFS and GTFS-R: Real time data is updated every 15 seconds, static data is updated once a day
