This is the first of two papers presenting the structure and the empirical estimation of a planning land-use—transportation model for the San Francisco Bay Area. The model is based on random utility theory and considers in an integrated way the location of urban economic activity and housing, and urban travel. The model is formulated as a nonlinear optimization problem and is shown to result in expressions which are consistent with behavior at the individual level.

The relative significance and influence of a variety of measures of urban form on household vehicle kilometers traveled, automobile ownership, and mode choice were investigated. The travel data came from the 1990 San Francisco Bay Area travel surveys, and the land use data were largely constructed from hectare-level descriptions provided by the Association of Bay Area Governments. After demographic characteristics were controlled for, the measures of accessibility, land use mixing, and land use balance—computed for trip-makers’ home neighborhoods and at trip ends—proved to be highly statistically significant and influential in their impact on all measures of travel behavior. In many cases, balance, mix, and accessibility were found to be more relevant (as measured by elasticities) than several household and traveler characteristics that often form a basis for travel behavior prediction. In contrast, under all but the vehicle ownership models, the impact of density was negligible after accessibility was controlled.

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.
