Public Transport - Daily Service Performance Report Summary Arriva (March – May, 2011)
Introduction The purpose of this report is to provide a performance analysis of Arriva Services in Luton based on ACIS BusNet Real Time Passenger Information system. The data contained in the report has been extracted directly from the VIX ACIS Operator Reports Database.
The statistics within the report are based on the percentage of scheduled journeys recorded by RTPI system, in relation to the current dataset.
Factors affecting reliability of results The report is based on the number of services and journeys tracked by the system. Hence, there will be a difference between the scheduled services as per the timetable and the actual journeys tracked. The factors affecting the reliability of the results are as follows:
1. Not all vehicles for Arriva have been fitted with the tracking devices. Hence, the use of the fitted vehicles is dependent on the Depot running. The output could have been drawn from just a single journey tracked for a day or month. 2. There are a few Coverage Deadzones where the transmissions are not possible (Luton Town area – Silver Street, Farley Hill areas, Dunstable areas). This would cause the service to be shown as running late or early. 3. Arriva uses its own system (21st Century) parallel to our RTPI system, which has also caused the system issues and hence, the report may not be reliable. However, since February 2011 we have minimised the affect and is still an issue to be resolved completely. 4. As the drivers have to input the correct details on the system as they get on and off the bus and while transfer of the drivers, this seems to have not been fully complied by them, therefore output generation can vary correspondingly.
External Causes of lateness or early journeys Apart from the journey or Service running actually late or early, there are some issues to be considered within the system. Issues that could show a service running late or early are: 1. Feed from the equipments to the server reaching late or vehicles and ticket machine faults. 2. Radio coverage deadzones. 3. Wrong input by the driver on the journey. 4. Service diversions due to road works and emergencies. 5. Power cuts and system breakdown.
No of journeys tracked for Arriva Services As the figures are based on the tracked journeys, the snap shot of Arriva’s tracked journeys against the actual journeys as per the registered services is shown in the graph below.

On the last RTPI meeting on 2nd June 2011, representatives from Arriva were informed about the number of services that were observed and how they were low in numbers. They were advised to keep track of the driver entries and increase the number of services to be tracked. Also in the meeting we were informed of several new vehicles arrival for replacement and we have already made arrangements for them to be fitted with the devices ready to be tracked.
