Starting point
Kerb space in the central districts had been allocated by designation decades earlier. Nobody had data on how it was actually used, so every proposed change was argued from anecdote.
What the city did
Instrumented a defined set of streets, recorded use by category and time, and published the data. Then reallocated space, and kept measuring.
What made it work
The sequence. Measurement came before reallocation, which meant the political argument was about the data rather than about whose intuition was correct.
What another city should take from this
The transferable part is the contract language and the publication commitment, not the technology. Both are published.
Note on figures
Result values in this case study are placeholders pending confirmation with the city. DEMO / REPLACE WITH VERIFIED DATA.
