However, the scale dependency problem, meaning that metrics may be biased as they rely on an arbitrary search radius or pre-defined jurisdic - tional division, remains unresolved. This paper proposes to apply clustering method to multi-scale indicators for evaluating aggregate patterns of jobs-housing relationship and commuting time–cost. We based our analysis on individual commuters extracted from cell phone data, a reliable substitute for travel surveys. After the commuter origin-destinations are carefully inferred, we draw two types of curves to represent the multi-scale charac- teristics of jobs-residence relationship and commuting efficiency. One is the multi-scale index curve (MSIC) of jobs-residence ratio that measured within multiple scales. Another is the probability density curve (PDC) of commuting time–cost. Then we applied the affin - ity propagation clustering method to the curves and detected six patterns of MSIC and ten of PDC. By comparing our result with the conventional methods we
