Real Time Public Transport Information

The TFI Real Time Ireland App is available free on Apple App store and the Google Play store.

The TFI Real Time Ireland App is the only App that provides live, real-time information for Go-Ahead Ireland, Dublin Bus, Bus Éireann, DART, Iarnród Éireann and Luas services. The App provides live updates, helping you plan your journey more efficiently on the TFI public transport network.

You can search by route or stop number. Simply click on the menu and select the relevant option. There is also an interactive map available, with each stop labelled. Once you’ve located your stop, click, and the app will direct you to the departures page.

Features include:

  • Real-time departure information and travel updates from Go-Ahead Ireland, Dublin Bus, Bus Éireann, DART, Iarnród Éireann Irish Rail and Luas services
  • Starred favourites can be set up so you can quickly access real-time bus / Luas / train information relevant to your own journey
  • Up-to-date information on all your bus / Luas / train arrivals
  • Stops and routes can be viewed
  • Route Line maps for all services with live bus positions for Dublin Bus

Real time information predicts the actual time of arrival by knowing where the bus is currently located. Your bus could arrive right at the time shown or it could occasionally get stuck in traffic, so the arrival time on display at the bus stop can sometimes change back and forward accordingly.  This service aims to provide the most immediate and accurate information to the waiting passenger at that point in time.

Frequently Asked Questions

How does the bus arrival information system work?

Buses must be equipped with an Automatic Vehicle Location transmitter, which can track the bus, using a Global Positioning System (GPS) and transmit the data in a standard protocol. On-board software predicts the arrival time at the next bus stop. This information is then sent to a screen at a transport stop or the App through a central control system. The screen at the bus stop counts down the minutes until the bus arrives. Updates are usually received from the vehicle location system at 30 second intervals, so information on the signs is regularly updated.

The Bus did not arrive at the time stated by the App/Website

The real time system is by its nature dynamic and is set to respond to factors on the road, including changes in traffic patterns, accidents, etc. In general though, the margin of error is less than one minute for predictions of five minutes away or less. For ten-minute predictions, the margin of error is less than two minutes, the margin increases the further away in time the prediction is, as the probability of intervening events increases. The system is continually fine-tuned in response to testing and feedback.

What are the factors that may affect the accuracy of Real Time Information?

Operational considerations
With such an extensive bus system, technical problems or operational disruptions can sometimes occur. Unanticipated problems such as a road closure or a mechanical problem can sometimes affect bus services. Occasional incidents can occur where a street is closed, for example on St Patrick's Day for a march or a big sporting occasion. In such cases, bus inspectors sometimes need to make a last minute change to scheduled bus services and it may not always be possible to reflect this on individual signs. The real time system was developed to respond to service disruptions as accurately as possible however, some disruptions could still affect the accuracy of the prediction.

Software and communication considerations
Occasionally a fault may occur in communications between the central server and the on-bus equipment. Sometimes software updates may be required for new services and schedules which can momentarily disrupt real time information.

Why does the waiting time increase or stay the same for a number of minutes sometimes?
