Transport Flows
Project
The idea is to map public transportation flows in Switzerland. The focus is on visualizing the network of SBB CFF (trains, S-Bahn). This visualization was later animated and published by the NZZ: Die Eisenbahn, die nie ganz schläft.
Purpose of the project
- Learning: Facts about the train network are revealed that are not obvious and surprise the consumer
- Aesthetics: the result is visualized in a creative and innovative way and shows the dynamic of the train network
- The visualization allows user interactions to have a deeper look into some details

Inspiration
Data
swisstrains. The data consists of train-schedules and a mapping from single trains to tracks on a map. As the track-data has been traced from Google Imagery we don't consider this data Opendata. Getting the tracks from OpenStreetmap would be a nice project for another Hackday.
Solution
Demo: http://flows.transport.opendata.ch/
Source: https://github.com/interactivethings/swiss-transport-flows/
Resource: http://www.fixithere.net/dvla-contact-number/
The following parameters were of interest for us
Time
- Departure
- Arrival
- Speed: average speed and speed changes on a train’s track
Track
- A train’s track on the map
- Stops per track
Train capacity
- Degree of capacity utilized (is the train crowded or not?)
- Length of trains ⇒ number of passengers
Stations
- Degree of tracks occupied (per hour, per day)
- Stations as intersections (how important is a station for the network?)
Train types
- Different types: IC, S-Bahn, Interregio etc.
- Name of a specific train (IC123)
Delays
- Per train
- Per track
- Waiting times of trains in a station
