Vix provides RTPI platform to Cambridge, world’s longest guided busway

Since 2005, Vix Technology has supplied a Real Time Passenger Information (RTPI) System to the City of Cambridge and the Bus Rapid Transit system, which services 3.6 million passengers per year along the longest guided bus route in the world.


In 2008, Vix also deployed an on-bus ticket solution for the principle city operators, Stagecoach and Go Whippet; it did not take long for ridership to grow higher than initially expected, and the system quickly began to expand.

Vix helped ensure a positive customer experience with the introduction of advanced RTPI on each stop on the busway. Transport vehicles are tracked via satellite and location details are sent to a central back office server and used to calculate next arrival times along a route. This information is then displayed to passengers at stops, including delays in service, which can be shown on these displays. RTPI can also be communicated to passengers on a range of media including web and mobile devices.

Vix also introduced an interoperable smart ticketing solution benefiting riders and operators alike. The smart ticketing allows passengers to board quickly and efficiently, while operators benefit by reducing the amount of cash needed to be carried on buses, which in turn reduces fraud. The system also provides comprehensive reporting and a database that interprets information to help run the service in the most efficient and effective way.

The successful Cambridge system is now looking to be expanded with work ongoing on a busway linking Dunstable to London Luton Airport. Vix was involved in the design and planning of the project and will be providing the ITS infrastructure using many of the same innovative technologies as were used for Cambridge.
