VBZ occupancy rates & WIFI registrations
#hardbrücke

Discover ways to determine the occupancy rate of the public transport vehicles based on WiFi registrations.



What is it about?

As part of a pilot project from May 15th to July 13th 2018, Verkehrsbetriebe Zürich tested a free WiFi service @VBZ at the stations "Albisriederplatz", "Hardplatz", "Hardbrücke", "Schiffbau" and "Escher-Wyss-Platz". A WiFi access point was installed at each stop area of the station. A station can consists out of two (in each travel direction one) or more stopping areas. There were two options for the devices to access the WiFi network of VBZ: through direct registration or by connecting without registration (depending on the WiFi settings of the device). Each connection was assigned to an access point according to the signal strength and the session was recorded continuously until the signal was still (sufficiently) present. Each device which was previously registered in the @VBZ network could subsequently be automatically recognized each time it appeared at any of the VBZ stations. Based on this information, a movement between the stops can be derived. A distinction between public transport, a car, a bicycle or a walk is, however, not possible.

Challenge

Can you estimate the occupancy rate of e.g. bus line 83, travelling at 8:19 am from "Hardbrücke" towards "Schiffbau" on 28.06.2018 based on WiFi registrations/connections?

  • The data of the counting system in the VBZ vehicles includes informtion about the number of passengers boarding and disembarking at stops, as well as about the number of passengers in the vehicles. The data consists of individual measurements of single trips, not of permanently measures values from all vehicles: T_Messfahrten.zip. Not Open Data. For TWIST2018 only.

  • Punctuality Data VBZ 2018 includes the exact arrival and departure times of the VBZ vehicles: FahrzeitenSOLLIST2018062420180630.csv. Open Data

The most important rule of TWIST 2018 is:
