An Integrated Land-Use-Transportation Model for the San Francisco Region: 2. Empirical Estimation and Results

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.
