Mertonian norms
Communism: Universal ownership of scientific goods and collective advancement
Universalism: Scientific validity is not related to positionality of the researcher.
Disinterestedness: Research for the common good, not individual / organizational interest.
Organized scepticism: Scientific work is constantly subject to critical evaluation.

Open source != open access
Lovelace, R., 2020. Open access transport models: A leverage point in sustainable transport planning. Transport Policy 8.
"Open access" is about
making work reproducible
making work public
making work accessible to a wide audience
Using open data and software in transport research
Coming exercise sessions
Problems will be shown in detail during the sessions
If you want, try to follow the instructions in advance
Can you come up with more advanced analysis / fusion with other data?
Coming presentation
Use of open simulator MATSim for automated vehicle simulation
Use of open data in France / Paris to create synthetic populations
Exercise session: Do you see other use cases?
Thank you!
