In this paper the empirical estimation of the POLIS model in the San Francisco Region is discussed. Data from 1975 and 1980 were used for the calibration. A three-step calibration algorithm was developed to estimate the travel parameters and the exponent of the agglomeration functions. A simulation of the calibrated model for the period 1975–1980 produced an employment and housing units allocation similar to the one observed.
