What about tracking studies
in light of urban design
and planning questions?
Visualising tracking data = creating maps
Maps = key language in urban design and planning
Sets of maps = building a design argument
Tracking data provide valuable insights
about urban quality
Are we building visual stories that are
relevant to urban design questions?
Trancik (1986) Finding Lost Space – Theories of Urban Design
Something about urban design
theory…
Something about urban planning
theory…
Patsy Healey – Spatial imaginations and urban ‘region’strategies
“uniplex metropolis” vs. “multiplex metropolis”
What do these theoretical
viewpoints share?
The plea to pay attention to multiple
viewpoints in urban design and
planning questions
..so the one map is not enough!
Ways of looking at tracking data in
sets of visualisations
1. Sets of multiple mappings of tracking data on a single scale
2. Sets of multiple mappings of tracking data on multiple scales
3. Sets of tracking maps combined with maps with ‘exogeneous’ data
…compiled as coherent visual stories??
some examples…
TYPE I : Sets of multiple mappings of tracking data
Viewpoints:
1. Switching between different
computer frames as map
creator or user
2. Showing a diversity of
patterns of space and time
use within a data set
3. Comparing data sets

On a single scale
TYPE II : Sets of multiple mappings of
tracking data on multiple scales
Stills from dynamic maps
All GPS-tracks dynamically
projected on a regional scale
All GPS-locations with ‘2-hour-tale’
projected on a local scale
TYPE II : Sets of multiple mappings of
tracking data on multiple scales
Selection of tracks:
only local trips
Selection of tracks:
only urban trips
Selection of tracks:
only regional trips
All tracks All tracks All tracks
TYPE III : Compiling sets of tracking maps
combined with maps with ‘exogeneous’ data
Overlay as organizing principle
of a set of maps
Interaction between urban processes as
organizing principle of a set of maps

tracks and other urban analysis maps…

Conclusion
Each type of set offers particular challenges, opportunities and
pitfalls to be addressed prior to data collection
Towards a qualitative research agenda on map use in tracking
studies?
> who is ‘using’ our maps? (what is ‘using’?)
> what do policy makers see when they look at our maps?
> can we increase the added value of tracking studies for
urban design and planning?
