Abstract Nowadays, the usefulness of smart card data for public transport planning is not questioned anymore.  Smart card automated fare collection systems continuously collect data on the transactional behaviour of the public transport users.  However, the use of such data for day to day planning activities is not a simple task.  This presentation discusses some challenges related to the analysis of smart card data through some applications done over the years at Polytechnique Montreal. The following elements will be addressed :

  • Error detection and data validation;
  • Conceptualization with a transportation object-oriented approach;
  • Destination estimation (for  “tap-in-only” systems);
  • Customer segmentation with data mining techniques, loyalty, impact of weather;
  • Public transport network characterization, ridership vizualisation;
  • New advances related to big data and the assessment of microelasticity.

The presentation will conclude on perspectives about the future of smart card data in planning and its integration with other modes of payment and other sources of data.



A keynote presentation will be given by one of the members of the Executive Committee of Netherlands Railways, the largest operator of passenger trains in the Netherlands.
