Guranteeing quality of crowdsourcing public transportion run-time information


3 Minute read

Public bus services in many cities around the world are controlled by private owners, which makes city-wide tracking bus service quality in real-time a challenging process.

Crowdsourcing this information in real-time is a promising approach in the absence of homogeneous information from the service providers. However, crowdsourcing suffers from other data quality issues, including non-uniform coverage of the bus network by bus riders.

Project goals

The goals of this project are to:

  1. Investigate the impact of inhomogeneous coverage on crowd-sourcing public transport service quality information.
  2. Search for countermeasures such as learning from history or incentivizing in real-time, to guarantee certain levels of information quality.
