Real Time Passenger Information System (RTPI)

In April 2016, Gloucestershire’s new bus Real Time Passenger Information (RTPI) system went live. It replaces the previous obsolete system
that had been in use since 2004.

The current RTPI system has been supplied and is being maintained by Trapeze Group UK (TGUK).

Gloucestershire County Council (GCC) is committed to ensuring that the RTPI system delivers reliable information to Gloucestershire’s bus commuters.

The RTPI system is very much dependent on the quality of data that the bus operators provide and that is why GCC and TGUK will be working closely with Gloucestershire’s bus operator.


The primary function of the Real Time Passenger Information system is to display when you bus is due to arrive at you bus stop, allowing you plan your journey more accurately. To minimise delays on your bus journey, the RTPI system also provides Traffic Light Priority (TLP) to late running buses (Note: only provided at junctions that have been upgraded to deliver TLP along key bus corridors).


Live bus movements are provided by the buses intelligent ticket machine to the RTPI server which uses this data to provide real time bus predictions on displays at bus stops.

RTPI system provides you with a countdown of live predictions of when the bus is expected to arrive. It is shown in the format of “XX mins” and provides a countdown displaying “DUE” when the bus is arriving at the stop, allowing you to plan your journey with confidence.


Real Time information provides you with accurate and dynamic information about your bus services, providind you with certainity about the arrival of your bus when you are waiting at the bus stop.

  • Real Time gives you flexibility and become confident about making smart decisions when planning your journey and travelling by public transport.
  • Improves your ability to access public transport and provide more ‘seamless’ journeys for yourself.


In the event, data from a bus stops being provided to the RTPI server (e.g. faulty ticket machine or network coverage lost), scheduled times will be displayed for that bus, until the fault has been resolved. The scheduled times are displayed in the 24 hour clock format.

Gloucestershire’s bus operators provide the scheduled data to GCC to upload on to the RTPI system.


Gloucestershire has thousands of bus stops. Unfortunately, due to funding limitations GCC cannot install RTPI displays at all of the bus stops. GCC has installed RTPI displays along key bus corridors.

GCC does recognise the value of providing RTPI at all bus stops. 


The RTPI back office constantly monitors the health status of the displays. When a display has lost complete power or communications the system provider is alerted through the automated fault management system.
