Root Cause Analysis Delay Determinants

A cloud-based reference architecture is being piloted for the structural analysis of determinants of unpunctuality of bus routes in public transport.

Development of a cloud-based reference architecture

Challenge

  • A public transport bus operator wants to better understand the reasons for the unpunctuality of its buses.
  • Up to now, root cause analysis has been carried out manually on the basis of regularly generated reports on a weekly basis

Solution

  • Using data on each individual bus journey as well as a variety of external environmental and event data, an algorithm is developed for root cause analysis and unpunctuality determination.
  • A cloud-based reference architecture is being built for data pre-processing and data analysis.

Result

  • Identification of traffic structural as well as non-plannable determinants for the punctuality of bus routes.
  • A dashboard shows a wide range of delay determinants at a glance.
  • A cloud-based reference architecture has been developed and tested against the use case.
