The goal of this project is to use mobile crowdsourcing to collect data on situations where the cyclists did not feel safe, but that didn’t lead to an accident. By logging and measuring head movement from smart earables, such as the Apple EarPod Pro, we want to automatically analyze where cyclists feel unsafe to provide urban planners with such information.

This is a project in collaboration with Andrii Matviienko (TU Darmstadt) and Bastian Pfleging (TU Eindhoven).

  abstract = {Today's level of cyclists' road safety is primarily estimated using accident reports and self-reported measures.
  However, the former is focused on post-accident situations and the latter covers only subjective input.
  In our work, we aim to build a full picture of cyclists' safety assessment via a two-dimensional taxonomy, which covers data source (internal/external) and type of data source (objective/subjective).
  Based on this taxonomy, we present a mobile sensing concept for quantified cycling safety that fills the identified methodological gap by collecting data about body movements and physiological data.
  Finally, we outline a list of use cases and future research directions within the scope of the proposed taxonomy and sensing concept.},
