What is Transport Data Science?

What is data science?

A field “to optimize the service contracts and maintenance intervals for industrial products”? (Davenport and Patil 2012)

“Data Science = Statistics + Machine Learning” or “Statistics + Computing + Communication + Sociology + Management”? (Vybornova, 2025)

Transport Data Science and Reproducibility

Transport data science is a discipline that:

  • “transform[s] raw data into understanding, insight, and knowledge” (Wickham, Cetinkaya-Rundel, and Grolemund 2023)
  • With reproducible and therefore falsifiable, scientific and scalable code.
  • For better understanding of and interventions in transport systems

Reproducibility is a continuous variable (Peng 2011)

Why make your research (more) reproducible?

Source: Raff (2023)

  • Scientific rigour
  • Benefits to your future self
  • Benefits to others
  • Huge increase in potential for impact

Example of fully reproducible research

From open source to open access

“In essence ‘open access’ goes beyond ‘open source’ in that users are … are encouraged [view and edit the source code], with measures taken in the software itself, and the community that builds it, to make it more user-friendly.””

Source: (Lovelace, Parkin, and Cohen 2020)

Open access research in ITS Leeds

We’ve put these ideas into practice, see github.com/itsleeds

How to get started with open source?

  • Identify a modular part of your work that could be useful for others
  • Follow ‘Unix philosophy’ and “do one thing well”. Source: github.com/juanfonsecaLS1

Principles for future research and practice

  • Faster
  • More gamified/responsive/accessible
  • More open/reproducible
  • Higher resolution
  • Bolder
