Real-time passenger information with the SmartPage e-paper display system

In public transport, access to accurate and reliable information is one of the most important factors shaping the passenger experience. Timely updates on schedules, delays, and unexpected changes have a direct impact on how services are perceived.
Developed by HC Linear, the SmartPage e-paper-based passenger information system offers a sustainable and cost-efficient solution to this challenge.
The system is designed to provide real-time, dynamically updated information for passengers waiting at stops, while minimising energy consumption and infrastructure requirements. Built on e-paper technology, SmartPage displays are particularly well suited to locations where installing LED or TFT displays would be too costly or technically complex.
One of the key advantages of e-paper technology is that it only consumes power when content is updated, making it extremely energy efficient. As a result, SmartPage devices can operate without a fixed power connection, using batteries or even solar energy.
Thanks to their paper-like appearance, the displays remain highly readable even in strong sunlight, providing consistently high contrast. Designed for outdoor use, the devices withstand harsh weather conditions and can be easily installed on poles or walls.
Through a remote management platform, all displays can be monitored and controlled in real time. Operators can manage content, check device status, and access diagnostic data from a single interface. In addition to timetable information, the system supports a wide range of content, including local news, community updates, and municipal messages, which can be scheduled across multiple pages.
User interaction is reflected in navigation activity, with deployed devices recording an average of 3,000 button presses per month per unit.
QR codes can also be displayed, allowing passengers to instantly access additional digital content or participate in surveys.
Feedback collected by HC Linear shows that the vast majority of users describe their first interaction with the display as positive. Many highlight the convenience of instantly seeing when the next vehicle will arrive, without needing to check mobile apps or printed timetables.
A significant share of respondents would welcome the wider deployment of such displays, particularly at busy hubs and at stops where no digital passenger information is currently available.
Energy-efficient digital infrastructure is playing an increasingly important role in the development of public transport, supporting both passenger convenience and cost-efficient operation. SmartPage e-paper displays offer a simple digital alternative to paper-based timetables and a foundation for a modern, future-ready passenger information system.
HC Linear, the Hungarian company behind the system, has more than 35 years of experience in the research, development, and manufacturing of electronic and software systems. Its R&D centre in Pécs is home to an in-house engineering team working on hardware, software, and system integration solutions.
HC Linear’s transport IT systems are deployed across multiple countries, cities, and regions, helping to simplify mobility for millions of passengers every day.

CanSat
High School Students in Pécs Developing Flight-Ready Satellite Systems
What exactly is CanSat, and how can a satellite simulation built by high school students reach an altitude of 1,000 meters?
The CanSat competition invites student teams to design and build a miniaturized satellite the size of a soft drink can. The payload is launched by rocket, deployed at approximately one kilometer, and descends by parachute while transmitting environmental data collected through onboard sensors. More than a technical challenge, the program introduces students to mission planning, systems engineering methodology, verification procedures, and professional-level technical documentation.
The Sat-Elite Assembly Team from Pécs has been competing for the third consecutive year in the Hungarian round organized by the Hungarian Astronautical Society as part of the European Space Agency educational initiative. Their work shows how secondary school students can approach engineering problems with the rigor and mindset typically associated with the aerospace sector.

Six Months to Deliver a Flight-Ready System
The Hungarian CanSat program has grown significantly in recent years, expanding from just a handful of teams to more than one hundred participants. Competing in such a field represents a considerable technical achievement.
Teams have six months to define mission objectives, design electronic and mechanical systems, develop embedded software, conduct validation tests, and prepare professional technical documentation. The top ten teams’ CanSats are launched to an altitude of 1,000 meters before descending safely by parachute. Following recovery, students present their flight data and system performance to a professional jury.
Recovery as a Mission-Critical Challenge
Although the launch captures the most attention, recovery often proves to be just as demanding. A descending payload released at one kilometer can drift several kilometers from the launch site depending on wind conditions. In previous competitions, some teams have spent hours locating their CanSat, and in rare cases the payload was never recovered.
To mitigate this risk, the Sat-Elite Assembly Team developed a proprietary radio and GPS-based tracking solution designed to provide accurate post-landing localization. Their goal extends beyond securing their own mission success. They are working toward a robust, reusable system that could support other teams in future competitions as well.
Integrated Hardware and Embedded Systems
Within the strict size and mass constraints defined by the competition rules, the team continuously enhances the functionality of its satellite. The current configuration incorporates thermal imaging capabilities, calibrated visible-spectrum cameras, temperature and humidity sensors, GPS positioning, and additional environmental measurement units. Structural improvements have been implemented to better withstand launch acceleration loads and landing impact forces.
Throughout the development process, team members have gained practical experience in printed circuit board design, embedded firmware development, mechanical integration, system validation, and formal engineering documentation. A comprehensive Critical Design Review video documents their progression from initial concept through subsystem integration to a flight-ready prototype, offering insight into both hardware architecture and software implementation.
From Competition to Orbit
Their achievements in previous competitions created new opportunities. In cooperation with the Budapest University of Technology and Economics, the team contributed to an experimental payload integrated into the HUNITY satellite. The satellite reached a 520-kilometer orbit aboard the SpaceX Transporter-15 mission.
The onboard experiment measures panel temperature, visible and infrared radiation levels, and attitude-related orientation parameters. The collected telemetry is transmitted to ground stations for processing and analysis, transforming classroom engineering into real orbital data acquisition.
More Than a Competition
Within the team, clearly defined roles reflect real engineering environments. Some members focus on embedded software, others specialize in electronics design, documentation, systems integration, or external communications. They actively participate in professional events and maintain a visible presence in the community, motivated by the belief that access to inspiring technological challenges can shape future career paths.
The final results will be decided in April among the top ten teams. Regardless of the outcome, supporting the Sat-Elite Assembly Team means supporting the next generation of engineers. Investing in young talent today strengthens the foundations of tomorrow’s innovation ecosystem.

Multichannel Passenger Information
Is a single app enough for modern passenger information?
Smartphone apps, just like in almost every area of life, have become a natural part of public transportation. Real-time service updates, route planning, and traffic alerts are now just a few taps away.
But is a mobile app really enough to ensure everyone gets the information they need? That’s the question we explore in this article.
Digital Inequality in Passenger Information
Research shows that digital inequality remains a significant issue in Hungary, especially across age, place of residence, and income lines. Older people, those living in rural areas, and lower-income groups have less access to, or are less likely to actively use, digital devices and the internet. These gaps reflect existing social inequalities and often deepen them further.
More than 87% of Hungarians over the age of 16 use a smartphone, but usage varies significantly by age group. Among younger adults aged 16 to 39, smartphone use is nearly 98%, while for those over 40, it drops to around 71%. In a typical Hungarian town with a population of about 3,000, roughly 1,700 people are over 40, and statistically, around 500 of them don’t own a smartphone. This means app-based passenger information alone cannot effectively reach this group.
Accessing real-time schedule information requires not only a smartphone but also a mobile internet connection, and mobile internet use tends to decline with age.
There are also significant regional differences. While smartphone usage is around 90% in Pest County and in the Western and Central Transdanubian regions, it falls below 80% in the eastern and southern parts of the country. Mobile internet usage is also lower in these areas; for example, in the Northern Great Plain region, it’s just 65%.
In Hungary, about 2.4 million people over 16 do not have access to mobile internet, meaning they cannot use app-based passenger information services.
A reliable and fair passenger information system must be accessible to everyone, regardless of who they are, where they are, or what device they use to get information. That’s why modern passenger information needs to be multichannel. Alongside digital apps, on-site information options must be provided to ensure every passenger can access the information they need.
In the next part of this article, we’ll explore on-site passenger information options. Beyond traditional paper timetable boards, there are many solutions available — like the SmartPage e-paper system. Don’t miss out!
