For decades, one of the most significant barriers to delivering real-time information at bus stops has been a practical one: lack of access to electrical infrastructure. 

In sprawling metropolitan areas like Portland, Ore., where TriMet operates a network of over 6,000 bus stops across 533 square miles, many stops weren’t designed with power connections in mind. 

However, in a transit landscape where riders expect timely, reliable updates at every step of their journey, this infrastructure gap also creates an experience gap.

Rather than letting that challenge go unmet, TriMet embraced it as an opportunity to innovate. 

In partnership with Connectpoint, the agency has launched one of the country’s most ambitious deployments of solar-powered ePaper digital signage, bringing real-time information to stops and stations that were once out of reach. 

More than 450 solar-powered signs have been installed systemwide — 111 since the beginning of 2024 — and plans call for continued expansion over the next five years.

“This innovation is transforming how we communicate with our riders,” said Joe Tobias, sr. project manager, at TriMet. “We’re no longer limited by where we can dig or connect to the grid. With solar-powered displays, we can deliver real-time information anywhere, which means a better, more reliable experience for everyone using our system.”

A Smarter, More Sustainable Solution

Unlike traditional LED signage, ePaper displays are powered entirely by solar energy and require no wired electrical connection. They feature high-contrast, glare-free screens that are easily readable in any lighting condition and use very little energy, allowing them to remain operational even during power outages. That reliability is key for keeping riders informed during service disruptions or emergencies.

These digital signs are also environmentally friendly and cost-effective, helping TriMet reduce its carbon footprint and avoid expensive installation and maintenance associated with grid-connected displays. 

“ePapers are highly scalable and replicable,” said Tobias. “It removes one of the biggest barriers to relying on existing electrical infrastructure. It’s a smart investment for any agency looking to modernize without overhauling its network.”

But it’s not just about technology, it’s about people. 

TriMet has intentionally prioritized equity in its site selection strategy, focusing early installations on high-ridership areas and communities with larger populations of low and limited-income riders. 

“We know when riders don’t have the information they need to ride, it can lead to less confidence and trust in our system,” said Tobias. “This solution allows us to bridge that gap.”

Real-Time Results

The results speak for themselves. 

Riders now report increased confidence in using the system, knowing they can rely on accurate information at key stops. Survey feedback shows strong public approval and growing comfort among transit users, particularly those in areas that previously lacked digital signage. 

The displays are also ADA-compliant, helping make the system more accessible for everyone.

“Since the introduction of ePaper displays, TriMet has observed improvements in rider confidence and engagement,” explained Tobias. “Riders are likelier to perceive transit as reliable, thanks to more visible real-time information. These factors contribute to overall system loyalty and support our long-term ridership goals.”

The displays are also connected to Connectpoint’s cloud-based Asset Management Platform, enabling TriMet to remotely update messaging in real time, even from a mobile device. This functionality enables hyper-localized alerts, such as detours or weather-related service impacts, without requiring on-site updates. 

“It has drastically improved our responsiveness and operational efficiency,” said Tobias. “During disruptions or emergencies, riders can still receive accurate, up-to-the-minute information.”

Award-Winning Innovation with a Replicable Model

In recognition of its trailblazing approach, TriMet and Connectpoint were named an Innovative Solutions Award winner for Technology. 

“We’re incredibly proud to win this award,” said Tobias. “It proves that all the hard work from our project team members on digital real-time information is worth it, and displaying real-time information in front of our riders makes TriMet more accessible, convenient, and reliable.”

The success of this project has also captured the attention of other agencies looking to replicate its impact. By combining solar energy, ePaper technology, and cloud-based content management, TriMet has developed a scalable, resilient model to improve transit communication. 

The system supports rider experience and helps agencies meet broader goals, from reducing emissions to expanding access and supporting mobility equity.

“This innovation is more than just a communications tool; it’s a catalyst for smarter, rider-friendly public transportation,” said Tobias. “It’s not just transforming the Portland area’s transit system, it’s setting a new standard for agencies everywhere.”

With continued expansion underway and public feedback driving future site selection, TriMet’s digital signage network represents the future of real-time transit communication — accessible, sustainable, inclusive, and built to last.
