Read GTFS
Cityliner loads routes, shapes, trips, and schedules from a public transport feed.
GTFS to city posters
Public transport schedules, drawn as city posters.
Cityliner maps route frequency from GTFS feeds. Thick, bright lines show where vehicles run most often.
City Pulse Atlas
Each image uses the same rule: more service means a stronger line.
How It Works
The poster is data-driven. The visual style comes after the network is measured.
Measure service
It counts how often route segments are used within the selected area.
Draw the poster
It exports a high-resolution PDF with route colors, water, borders, and optional logos.

Public engine. Private production.
The code is public. Raw feeds, processed data, print masters, customer files, and commercial workflow stay private. Commercial posters use logo-free layouts unless logo rights are confirmed.
