PTIPS works by combining, on the one hand, schedule and route path information for buses performing timetabled services (as opposed to, say, charter trips), and on the other hand, live ___location data transmitted by the buses to PTIPS.

PTIPS receives XML data files from the public and private bus operators, which contain information relating to planned trips (for example, route paths, trips & schedules, bus stops etc.)

Each bus that PTIPS tracks is equipped with a hardware device that records its ___location via [[Global Positioning System|GPS]], and transmits it to the central PTIPS servers via the 3Gcellular radio communications network. Buses transmit these messages at certain intervals (which are configurable, and which vary depending on what the bus is doing), and also when they pass certain points along their intended route. Apart from GPS ___location, the transmitted messages also include information about the vehicle and which trip it is doing.

With the above information, PTIPS can compare the ___location of a bus performing a certain trip, at a certain point in time, with where it should be, based on the planned route and timetable data.

==Real time apps==

[[Transport for NSW]] worked with several developers in late 2012 to create, and release smartphone applications with access to the realtimereal-time bus data provided from PTIPS.

Released in December 2012, several [[iOS]] and [[Android (operating system)|Android]] apps went live on their respective App Stores, allowing customers to open the apps, and track where their buses were in realtime, as well as any delays or timetable changes as they occur. In 2013, this realtime data was further expanded to provide live train information from [[Sydney Trains]], [[Hillsbus]] and [[Busways]] Blacktown as well.
