Visualise mobility changes before they happen.
Plan the fix.

TrafficTwin helps understand how a road closure, event, or public transport change can affect traffic. You can compare options, see the impact on a map, and discuss decisions with clearer evidence.

Traffic planning dashboard with city roads, route lines, and comparison panels

A practical way to compare mobility options.

  • Plan road closures with less guessworkTest roadworks, events, and temporary traffic deviations before they are used.
  • Visualise and compare different mobility scenarios Compare public transport changes, traffic lights, lane speeds, lane closures, diversion plans,...
  • Share results people can readUse maps, visualisations, and various mobility indicators to support the discussion.

Bring your own mobility question.

TrafficTwin is most useful when there is a real decision to prepare: a closure, a diversion plan, a major event, or a public transport change.
