Abstract

We are developing a statewide urban growth model for California. It will be run in iteration with the California statewide travel model to evaluate major transportation improvement scenarios, such as freeway widenings and high speed rail. In addition, we will evaluate land use policies intended to provide for more affordable housing and for habitat protection. This model is uniquely capable of providing performance measures for total travel, travel delay, mode shares, economic development, wages, economic welfare, economic equity, rents paid by households and firms, energy use in vehicles and buildings, greenhouse gas emissions, vehicular air pollution, loss of agricultural lands, habitat loss, and erosion potential. We propose a framework for interpreting all of these data, based on recent advances in the theory of well-being for persons and for nations.
