Keolis tests a new, environmentally-friendly passenger information system

Keolis is testing a new, solar-powered, real-time information system at some of its bus stops. Keolis is a pioneer in connected and sustainable mobility solutions. An innovative new passenger information system is currently on trial in the French towns of Goussainville and Rennes, where solar-powered e-paper displays are providing travellers with real-time transport information.

E-paper trials in Goussainville and Rennes

Keolis is constantly searching for new ways to enhance customer experience across its networks and passenger information is one of the Group’s key priorities. E-paper (electronic paper) displays are currently being tested at five stops in the French city of Rennes. These user-friendly digital screens use the same technology as e-book readers and can even be installed on board buses.  The Papercast technology is also on trial in the town of Goussainville, where a device has been integrated into the existing display panel at the Roissy Village stop, close to the busy Charles de Gaulle airport.

Up-to-date information in real time, all the time

The Keoscopie Digital Survey revealed that passengers expect transparent, up-to-date information at every step of their journey. Electronic paper plays a vital role in helping Keolis answer this need. Traffic information displayed on the innovative screens can be refreshed automatically, minute-by-minute, thanks to an integrated 3G/4G connection. The displays can also be used to:

  • broadcast up-to-date information on service disruption directly to all stops, eliminating the need for staff intervention on the network
  • relay special offers, network communications or local news quickly, simply and efficiently

The weather-resistant, vandal-proof screens boast a wide viewing angle and optimised readability, even in direct sunlight or at night.

Environmentally-friendly and easy to install

E-paper is ideally suited to digital display applications, thanks to its energy saving properties. The electronic ink technology used in the screens consumes very little energy and devices are powered by solar panels connected to an integrated battery. Electronic paper offers a cheaper and more sustainable solution to current LCD displays: screens are quick and easy to install and can be integrated directly into existing display panels with no need for connection to mains electricity.
