Sensor Bike

Citizen science project to collect cycling data

Participants of the sensor workshop grouped around a table while the speaker explains the sensors.
At the sensor workshop in May 2025, participants were able to build their own bike sensor and mount it on their bike.

Together with 30 citizens who cycle a lot in our city, the state capital of Wiesbaden is collecting relevant data on cycling in Wiesbaden. The data experiment is initially scheduled to run for six months.

The multifunctional sensors collect environmental data, record the surface conditions (cobblestones, asphalt, etc.) and the probability with which overtaking vehicles have or have not maintained the minimum overtaking distance of 1.50 meters prescribed by road traffic regulations. All of the cyclists' data is aggregated and visualized in a map view.

The data provides indications of potentially dangerous situations for cyclists in the urban area and is intended to support the targeted expansion of the cycling infrastructure.

The campaign data and further information on the data can be viewed in the new dashboard "Data world: Bicycle use in Wiesbaden".

Committed people in our city [TN1] are participating in this project by collecting data during their everyday bike rides. Professors and students from the Rhein Main University of Applied Sciences are also involved in the project. Together with the supporters of this project and the City of Wiesbaden's Cycling Office, the data will be jointly examined and analyzed.

The Citizen Science project was launched during the Smart City theme week "fahrRAD" (May 2025).


The advantages:

  • The project provides valuable data that did not previously exist in this form.
  • The data experiment provides indications and clues that can support the targeted expansion of cycling infrastructure and an improvement in road safety.
  • Urgent measures can be prioritized thanks to a data basis that covers the entire urban area.

Who benefits from it?

  • All road users benefit from improved cycling infrastructure, whether they are cycling, driving or walking.
  • Vulnerable groups in particular (such as children and young people or older people) can move more safely in traffic thanks to an improved cycling infrastructure.
