MetroRadar on Radio Warszawa: how the app warns passengers about metro disruptions

Przemysław Królikowski, creator of MetroRadar, joined Poranek z Radiem Warszawa on 2 June 2026. The ten-minute conversation covered an app created to warn passengers quickly about failures and other disruptions on the Warsaw metro.

The starting point was familiar: someone arrives at the station and only then learns that trains are not running on part of the line. MetroRadar aims to move that moment earlier, so the alert arrives before the journey begins.

The programme discussed a system based on operator announcements and user reports. Official information confirms the scope of a disruption, while a passenger at the scene may notice a stoppage, a closed entrance or growing crowds earlier.

The two perspectives work together only when sources are clearly labelled. A user should always know whether they are reading an operator announcement or a community signal that still needs confirmation.

• check the publication time and latest update,
• compare the line, direction and boundary stations,
• distinguish an official announcement from a passenger report.

The episode, titled “Metroradar Warszawa – aplikacja, która uprzedza o awariach metra”, lasts 10 minutes and 26 seconds. It is available on the Radio Warszawa website and on Spotify.

Thank you to the station for the opportunity to explain the project and the community's role in passing useful information along more quickly.
