The Central Question
QUESTION
How does daily mobility shape access to opportunity in fast-growing cities?
Connected to: Commuters described short routes that still felt hard to complete., Field notes showed long, uncertain waits at transit stops., Infrastructure quality varied sharply within short distances across wards., Which infrastructure decisions create invisible barriers?, Standard access maps used straight-line distance, not lived experience.
