Heat-Resilient Mobility and the Fifteen-Minute City

This interdisciplinary review examines heat-resilient mobility and proximity-based urban planning. The organizing question is how accessibility gains can be preserved when heat exposure changes who can walk, cycle, or wait for transit. Ten related scholarly sources are synthesized through a decision-centered framework spanning problem definition, mechanism, measurement, evaluation, implementation, and governance. The review does not invent experiments, pooled estimates, or unreported quantitative results. It instead evaluates the strength and transferability of the available evidence, with particular attention to treating geometric proximity as equivalent to usable access under extreme heat. The resulting framework links technical or empirical performance to explicit use conditions and identifies tests that should precede wider adoption in neighborhood-scale climate adaptation and low-carbon mobility.
