Real-time traffic intelligence for Danish roads

The Challenge

Trafik Alarm needed a comprehensive traffic alert platform with native mobile apps and a web dashboard, aggregating real-time data from multiple Danish sources into a single, fast experience. Danish commuters were frustrated by fragmented traffic information spread across government websites, radio stations, and social media — there was no unified platform delivering personalised, real-time alerts for their specific routes.

  • Traffic data was fragmented across 5+ Danish government and private sources
  • Commuters needed personalised alerts for their specific daily routes
  • Alert delivery had to be under 2 seconds from event detection to user notification
  • Map visualisation needed to handle thousands of concurrent traffic events

Our Approach

Built native iOS and Android apps with real-time push alerts and interactive map visualisation, plus a WordPress website and React.js admin panel. The Node.js backend aggregates traffic data from 5+ Danish sources via WebSocket connections, normalises events into a unified format, and routes personalised alerts to users based on their saved routes and preferences.

  • Real-time data pipeline aggregating 5+ Danish traffic data feeds
  • Sub-2-second alert delivery from event detection to push notification
  • Interactive Mapbox visualisation with clustered traffic events
  • Personalised route-based alerting with user preference management
  • WordPress public website with React.js admin dashboard

Frequently Asked Questions

Where does Trafik Alarm get its traffic data?

The platform aggregates data from 5+ Danish sources including government traffic management systems, the Danish Road Directorate, police incident feeds, and community reports. All data is normalised into a unified format for consistent alerting.

How fast are the traffic alerts delivered?

From the moment a traffic event is detected in any data source to when the push notification reaches a user's device takes under 2 seconds. This speed is critical for alerting drivers about accidents or sudden road closures on their route.

Can users customise which alerts they receive?

Yes. Users save their daily commute routes and set preferences for alert types (accidents, road work, speed cameras, weather). The system only sends notifications for events that affect their specific routes.
