Telia, together with partners Traffic Systems Incorporated, and Daktronics, have launched their first solar-powered Real-Time-Passenger-Information (RTPI) signs on Queens Boulevard in New York. Telia IoT Edge Smart Gateways currently provide public transport information to over 500 bus stops and digital information signs across New York City.
The system provides real-time bus arrival times to passengers and assists the visually impaired with spoken information.
The new displays use ultra-low-power Etulipa Electro Wetting E-Paper Technology from Daktronics that can run on solar power. The two-sided displays are designed to maintain clear readability at 25 meters/80 feet, just like the 500 existing AC powered RTPI signs throughout the five boroughs of NYC that Telia already connects. The battery in the system uses recyclable Lithium Iron Phosphate Technology and provides a battery lifetime in excess of ten years in this application.
Solar signage offers both environmental and cost advantages for cities. Because they don’t require heavy machinery for excavation to run power cables under the sidewalk, they are cheaper, faster and cleaner to install. On top of this, they provide operational cost savings as the solar panel will generate free electricity for decades.
“This is a great progression for our smart information systems, not just in New York, but also in other cities with green ambitions. We were originally included in New York’s Smart City initiative thanks to the security characteristics of the Telia IoT Edge. It feels great to be able to take the next step together with Traffic Systems, Inc. and Daktronics and add renewable energy to our offering” says Björn Hansen, Head of Telia IoT.
This is the first step of Telia, Traffic Systems, Inc. and Daktronics’ expansion into solar-powered RTPI signs in both the US and Europe. Solar RTPI signs are just one of the ways in which Telia IoT is helping to reduce the environmental impact of public transport while providing a better experience for commuters.
