PlaceFinder is an application designed for PKP Intercity passengers who cannot find a ticket with a guaranteed seat on the entire route. Thanks to an intelligent algorithm, the application searches for possible combinations of transfers... between seats - allowing for a more comfortable journey with a seat on selected sections. PlaceFinder analyzes the availability of seats in the e-IC2 system and suggests which parts of the route can be traveled sitting down, even if the entire route is already sold out. This is a practical solution especially for people traveling in the peak season or on popular routes. Comfort, smartness and mobility - all in one application.
