User-friendly and accessible mobile app for De Lijn

To ensure user-friendliness for all users, the existing mobile app was completely renewed. During this renewal, extra attention was paid to increasing the user-friendliness and accessibility of the app. The BLS app has been integrated into De Lijn's existing updated app, which is now able to read out routes and information about a stop. In addition, a new route planner has been integrated and users can see even more accurate real-time information.

In the new design of the app, we mainly focused on easy and user-friendly navigation, providing clear context when reading the screen and supporting larger text sizes. This means that De Lijn can call its app accessible, and they are more than ready for accessibility audits for mobile applications in the public sector.

In addition to the visual renewal of the app, we also worked on other innovations and improvements. With the motto "what is real-time, can still be real-timer" we looked at possibilities to make the app even more reliable for users.

Improved real-time info and a crowd barometer

At the start of the projects, we focused on improving the basic functionalities such as improving the real-time information and integrating the crowd barometer. With this crowd barometer, a traveler can see how busy it is on a particular bus or tram.

In terms of real-time information, we have made tremendous progress. In 97% of the cases, the traveler can check the app to see when a bus or tram will arrive at the stop. More than 92% of the information shown corresponds to reality with a margin of one minute or less. In addition, travelers can save routes as favorites and future trips are made easier because these routes can be quickly found in their own profile. The home screen shows the favorite stops along with the real-time information.

Our approach began with a thorough analysis of De Lijn's user base, focusing on visually impaired users, casual travelers, and daily commuters. We held collaborative workshops with De Lijn's team to identify key pain points in the existing apps and define the functional and accessibility goals for the new application. Accessibility guidelines for public sector mobile apps were central to our strategy.

We integrated the features of the outdated BLS app into the main app to provide a unified solution that met the needs of visually impaired users through screen reader technologies like VoiceOver for iOS and TalkBack for Android. For navigation, we replaced the confusing hamburger menu with a more intuitive bottom navigation bar, enabling users to quickly access essential features like ticket purchases, route planning, and personalized settings.

Real-time data was a critical component of our plan. By improving data integration, we ensured that bus and tram schedules were accurate 97% of the time, with 92% of real-time updates aligning to within one minute. Features like favorite routes, saved profiles, and a crowd barometer for gauging bus occupancy were developed to enhance usability. We also implemented best practices in UI/UX design to simplify navigation, support larger text sizes, and provide clear contextual cues for screen readers.

We prioritized continuous feedback, testing the app iteratively with real users, including those with disabilities, to refine its accessibility and functionality. Finally, we ensured that the app was future-proof by using scalable architecture and maintaining compatibility with App Store and Google Play Store requirements.

After improving the basic functionalities and real-time information, we mainly shifted our focus to the design and user-friendliness of the app to make traveling even more comfortable. We replaced the previous hamburger menu with a navigation bar at the bottom of the screen. This gives users easy access to the various functions of the app, including purchasing tickets, plotting routes by train, tram, metro or bus, notifications for departure warnings and personalized information.

You can find the new app in the App store and Google Play Store.
