Gruppo Torinese Trasporti S.p.A. (GTT) selects Papercast’s next generation solar powered e-paper bus stop display to modernise the city with a sustainable technology and to improve passenger satisfaction.


Part of a wider city modernisation programme throughout Turin, GTT aims to improve the quality of information provided to passengers at the bus stop with a self-sustainable future proof solution that can be indefinitely solar powered. The current LCD and LED passenger information displays can be a drain on power, requiring battery replacements every two-weeks across the network.


GTT set out to replace its current LCD based passenger information system with a sustainable, standalone, solar powered display solution. During extensive supplier due diligence, GTT evaluated like-for-like product performance during field testing and selected Papercast’s e-paper display technology.

Papercast 13.3” e-paper displays with 20W solar power modules are operational across central Turin. The displays are fully integrated into GTTs live GTFS data feed to show live arrival information – without the need to ever change batteries.


Papercast has demonstrated that it has a far superior technology compared to the alternatives. It offers significantly better power efficiency and wins on all other technical points, including screen visibility, content management and overall design.

Alberto Forchino, Head of Telematics Systems at GTT, says: “We didn’t set-out specifically with e-paper in mind. We knew that technological advancements had surpassed LCDs and LEDs in outdoor, standalone environments but were open minded around the technology we moved forward with. E-paper, in particular Papercast’s technology, far exceeded our expectations”.
