Real time passenger information (RTPI)

The Surrey Real Time Passenger Information (RTPI) system provides live information about the arrival of services at bus stops across the county. The majority of bus services operating in Surrey are included on the system which tracks the buses and predicts the arrival time in number of minutes counting down at the stops. This information is displayed at bus stops fitted with an electronic display and is also available through your mobile phone.  Find out more about the mobile phone service. The RTPI system provides confidence for passengers to make an informed and smart choice to travel by public transport.

Surrey County Council has recently started a new contract with our supplier of the RTPI system, and is currently in the process of upgrading the existing system to improve the accuracy and reliability of live bus information available to the public. Below you will find the updates of the RTPI system upgrade works.

System upgrade works

Update communication #6 - October 2016

With the upgraded bus Real Time Passenger Information (RTPI) system now fully operational, Surrey County Council’s (SCC) commitment is to ensure that the RTPI system delivers accurate and reliable information to Surrey’s bus users.  The bus RTPI system is very much dependent on the quality of data that the bus operators provide and that is why SCC and our RTPI contractor (Trapeze) continue to work closely with Surrey’s bus operators.

Southdown now has all its fleet equipped to be shown on the RTPI system. Other bus operators with the ability to show RTPI information are:

  • Abellio
  • Arriva
  • Metrobus
  • Safeguard
  • Stagecoach

SCC have put in place targets for the system to be operating against, these include:

  • At least 85% buses on the system being tracked.
  • At least 85% accuracy for real time predictions.
  • 100% accuracy for scheduled bus times. Scheduled times are only shown when a bus is not being tracked by the system.

The RTPI systems Key Performance Indicator (KPI) reports, provide Surrey County Council with the means to review the performance of each bus operator.

Analysing the last three months Bus on Trip KPI graphs (PDF) it can be seen that collectively the bus operators are about 10 -15% short of achieving SCC’s target (85%) for tracked buses.

Over the last three months, the RTPI system has been generating an average of almost 74% of real time predictions across Surrey’s RTPI equipped bus stops. This is 11% below SCC’s target of 85%. SCC are reviewing system reports to identify potential causes behind poor results and will be working with the bus operators over the next few months to deliver improvements.

As part of SCC continued monitoring of the systems performance, six-monthly on-site reviews are carried out with Trapeze. A different location within Surrey is chosen, with the sites to be assessed only being revealed to Trapeze on the day. To date, two on-site reviews have been held, with the first one in Guildford and the most recent one in Redhill/Reigate.  On both occasions positive results were obtained with only a few minor corrective actions being identified for Trapeze.

As well as daily monitoring of the RTPI system, the large screens installed at bus stations, hospitals and shopping centres are monitored regularly. After a recent software upgrade there are noticeable improvements to the percentage of RTPI predictions being shown on the displays.

To improve bus journey reliability we are in the process of upgrading 18 junctions in Guildford to deliver priority for buses at traffic lights, which will allow late running buses to be given an earlier green signal at the junction, allowing lost time to be made up if it does not have an adverse effect on other vehicular traffic. These junctions have been configured on the RTPI system and we will be shortly proceeding ahead with the installation of hardware at each of the junctions.

Update communication #5 - February 2015

Surrey County Council remains committed with the delivery of the upgraded bus Real Time Passenger Information (RTPI) system by working closely with Surrey's bus operators and RTPI contractor Trapeze.

Last month we witnessed the completion of the remaining RTPI display System Acceptance Tests (SAT) in Guildford, Woking and Redhill. We also oversaw the testing of the next stop displays being used by some of our bus operators.

We are currently completing the remaining back office and fault management tests before moving into the system maintenance and expansion phase with Trapeze in March 2015.

We continue to engage all the bus operators to obtain their latest set of RTPI schedule data. Without the correct data from the bus operators the system will not be able to deliver accurate live information on bus services. Summary update on the large bus operators includes:

Abellio – RTPI services have been activated with good results. The active buses report for Abellio has shown approximately 90% of its Surrey fleet is being tracked by the RTPI system with the same percentage of buses being on trip and providing predictions.

Stagecoach - Work continues with the operator to complete the upgrade to a new SIRI approach to providing RTPI data directly to the Surrey Trapeze system. Trapeze has completed the system development work required in readiness to accept the new operator data feed. We are expecting Stagecoach to make this feed available early in the new financial year.

Arriva - Good progress has already been made to develop the new direct operator feed of RTPI data into the Surrey system. During the recent SAT tests some errors and limitations have been identified with the data feed. These issues are currently being addressed by Arriva and their system contractor. Once complete this is expected to increase the overall level and quality of predictions currently being seen on street for Arriva services.

Once the core system has been accepted further system improvements will be made, including bus priority at signalised junctions and new RTPI signs installed at key bus stops.

We will be publishing Key Performance Indicator (KPI) reports on a regular basis on the Surrey CC website once we are fully satisfied with the upgrade tests. The KPI reports will help identify and rectify any system and service issues with the bus operators and Trapeze. The reports will include the following:

  • Active Buses
  • Sign Prediction Accuracy
  • Sign Clear Downs
  • Sign Visits
  • Traffic Signal Junction Priority

Good progress has already been achieved with the RTPI system upgrades being delivered with our contractor. However, we acknowledge that there are still areas for improvement, including individual operator services and specific sites with electronic information displays, and we continue to work with the operators concerned and our contractor to address any known issues. We are moving in the right direction. RTPI systems are very complex and require a large number of inputs and processes to be functioning correctly for the system to provide the end output of accurate live bus arrival/departure information. The live bus information is made available on electronic signs and through mobile, web and smartphone channels.

The next update will be published in March 2015.

Update communication #4 - November 2014

Surrey County Council continues to work closely with the bus operators and it's RTPI Contractor (Trapeze) to deliver Surrey's upgraded bus Real Time Passenger Information (RTPI) system.

Last month we witnessed System Acceptance Testing (SAT) of RTPI displays in Guildford, Woking, Camberley, Redhill and Reigate. We also oversaw the testing of the back office software carried out by Trapeze. So far, the results of the SAT have been excellent with only a few changes identified for Trapeze to action within the next few weeks. During December and into the start of the New Year we will be aiming to complete the remaining, tests, these include:

  • Testing Next stop displays on the bus
  • Testing bus communications system
  • Testing the electronic Fault Management System (FMS). The FMS will be handling the report of faults right through to agreed fault rectification.

We continue to engage all the bus operators to obtain their latest set of RTPI schedule data. Without the correct data from the bus operators the system will not be able to deliver accurate live information on bus services. Summary update on the large bus operators includes:

Stagecoach - Work continues with the operator to complete the upgrade to a new SIRI approach to providing RTPI directly to the Surrey Trapeze system. Trapeze has completed the system development work required in readiness to accept the new operator data feed. We are expecting Stagecoach to make this feed available over the coming weeks.

Abellio - New software is now in place with the operator, enabling the required schedule data files to be built. This is a lengthy process for Abellio to complete for all services operating in Surrey. Trapeze have recently started the process of updating our system with the new service files that have been supplied, and expect to activate RTPI for Abellio services in Surrey as soon as the data files have been validated.

Arriva - Good progress has already been made to develop the new direct operator feed of RTPI data into the Surrey system. During the recent SAT tests some error and limitations have been identified with the data feed. These issues are currently being addressed by Arriva and their system contractor. Once complete this is expected to increase the overall level and quality of predictions currently being seen on street for Arriva services.

Once the core system has been accepted further system improvements will be made, including bus priority at signalised junctions and new RTPI signs.

Early in 2015 we will be publishing Key Performance Indicator (KPI) reports on a regular basis on the Surrey CC website. The KPI reports will help identify and rectify any system and service issues with the bus operators and Trapeze. The reports will include the following:

  • Active Buses
  • Sign Prediction Accuracy
  • Sign Clear Downs
  • Sign Visits
  • Traffic Signal Junction Priority.

Whilst the upgrade works are being carried out there will be drops in the amount of real time information being provided. We will try to keep theses drops to a minimum and will keep you posted on how the works are progressing over the next few months.

We are moving in the right direction. RTPI systems are very complex in their nature, and not unique to Surrey. These systems require a large amount of inputs and processes to be in place and operating in synchronization for the system to provide the end output of accurate live information and predictions on signs, and available through mobile, web and smartphone channels.

Update communication #3 - October 2014

Surrey County Council continues to work closely with the bus operators and it's RTPI Contractor (Trapeze) to deliver Surrey's upgraded bus Real Time Passenger Information (RTPI) system.

The upgrade works to the core system (i.e. hardware and software) have been completed. However, we have had to postpone system acceptance testing until all the bus operators have provided us with their latest set of RTPI schedule data, for the Surrey bus services they provide. This data is required for the RTPI system to function. Bus timetable changes have recently been made by Arriva on the 28th September, however, the new RTPI data supplied directly by Arriva has been found to contain a number of errors. These errors are now being corrected by Arriva before the revised service information can be sent out to all signs on the street. We are also currently awaiting new schedule data files from Abellio for the services they operate on the RTPI system in Surrey, to replace the outdated data currently held.  In this case, we have had to take the decision to temporarily remove all Abellio services from the system whilst we await the corrected data files to be supplied from the operator. We recognise that in order to gain the public's confidence on the upgraded RTPI system it is absolutely imperative that we have the correct data from the bus operators, and we will only proceed with the acceptance testing once this data is received from all operators and has been successfully imported into the RTPI system by our contractor. It is only at this stage that the system is able to function correctly and provide the all important live bus arrival predictions to passengers on the street.

Our system acceptance plan remains the same, to test the upgraded RTPI system in each of the three regions – dates to be confirmed.

  • Day 1: Guildford area
  • Day 2: Woking and Camberley area
  • Day3:  Redhill & Reigate area

Once the core system has been accepted further system improvements will be made, including bus priority at signalised junctions and new RTPI signs.

Recent upgrade achievements include:

  • Successfully agreed the system acceptance tests with Trapeze.
  • Bus operators are being trained on how to use the new RTPI system software.  The new software features will deliver improved fleet management tools to support bus operators with the day-to-day running of their bus services.

These KPI reports (see list below) will help identify and rectify any system and service issues with the bus operators and Trapeze. The Council envisages publishing these KPI reports on a regular basis on the Surrey CC website.

  • Active Buses
  • Sign Prediction Accuracy
  • Sign Clear Downs
  • Sign Visits
  • Traffic Signal Junction Priority

Whilst the upgrade works are being carried out there will be drops in the amount of real time information being provided. We will try to keep theses drops to a minimum and will keep you posted on how the works are progressing over the next few months.

Update communication #2 – August 2014

Surrey County Council continues to work closely with the bus operators and it's RTPI Contractor (Trapeze) to deliver Surrey's upgraded bus Real Time Passenger Information (RTPI) system.
The upgrade works to the core system (i.e. RTPI server, data communication links and software) are on schedule to be completed by the end of August.

During August we will be finalising the system acceptance tests with Trapeze so as to ensure the upgraded system works according to our specified requirements and performance levels. Three separate test days during September 2014 will be arranged for the areas of the county that the RTPI system covers. Proposed test dates are:

  • Day 1: Guildford area (3rd September)
  • Day 2: Woking and Camberley area (5th September)
  • Day3: Redhill & Reigate area (w/c 22 September).

Once the core system has been accepted further improvements will be made to deliver even more system improvements, including bus priority at signalised junctions and new RTPI signs.
July upgrade achievements include:

  • Successfully installed the first two new data communication links with Arriva and Abellio.  For the end user this will mean they will have access to a greater number of real time services from these two bus operators.
  • Bus operators are being trained on how to use the new RTPI system software.  The new software features will deliver improved fleet management tools to support bus operators with the day-to-day running of their bus services.
  • Successfully completed the 'factory acceptance' testing with Trapeze. This has now triggered the preparation for the live system acceptance testing.
  • Key Performance Indicator (KPI) reports have been agreed and finalised with Trapeze to monitor overall system performance. These will include the following measures:
  • Active Buses
  • Sign Prediction Accuracy
  • Sign Clear Downs
  • Sign Visits
  • Traffic Signal Junction Priority

These KPI reports will help identify and rectify any system and service issues with the bus operators and Trapeze. The Council envisages publishing these KPI reports on a regular basis on the Surrey CC website.

Whilst the upgrade works are being carried out there will be drops in the amount of real time information being provided. We will try to keep theses drops to a minimum and will keep you posted on how the works are progressing over the next few months.

Update communication #1 – July 2014

Surrey County Council has set the wheels in motion to enhance the performance of Surrey's current bus Real Time Passenger Information (RTPI) system.  The upgraded RTPI system will be delivering a higher proportion of real time bus services across the county, with improved accuracy and greater accessibility (i.e. at bus stops and through any device with an internet connection).

Surrey County Council and its bus operators are working closely with the RTPI system providers (Trapeze) over the next few months to ensure the necessary upgrades are in place before September 2014.

The upgrade works will include:

  • Delivering a new communications infrastructure between the RTPI server and each of the bus operator's back office systems to ensure the provision of reliable and accurate data.
  • Bus operators will have access to improved fleet management tools to support them with the day-to-day running of their bus services.
  • The Council will have access to Key Performance Indicator (KPI) reports that will support them to identify and rectify any service issues with the bus operators and Trapeze. The Council envisages publishing these KPI reports on a regular basis on the Council's website.

Whilst the upgrade works are being carried out there will be drops in the amount of real time information being provided. We will try to keep theses drops to a minimum and will keep you posted on how the works are progressing over the next few months.
