Equity Analysis of Land Use and Transportation Plans Using an Integrated Spatial Model

This paper describes a study to investigate how a new form of spatial economic model can be used to evaluate the equity effects of land use and transportation policies that reduce greenhouse gas emissions. The Activity Allocation Module of the PECAS Model of the Sacramento Region is used to simulate two scenarios for the year 2035 arising from a recent planning process, ‘Business As Usual’ and ‘Preferred Blueprint’. Advanced aggregate travel models and activity based travel models have been applied to evaluate distributions of travel time and cost effects of transportation and land use policies across different socio-economic groups. But the PECAS model system, with its representation of the interactions among the transportation system and the rest of the spatial economic system, facilitates an evaluation of the distributions of a wider range of economic impacts, including wages, rents, productivity and/or changes in consumer surplus, for segments of household, labor by occupation, and industry categories. The PECAS model is applied to the policy scenarios to illustrate the distributional measures that can be obtained from this type of model and to provide insights to the equity effects of different transportation and land development patterns. The results shows that a more compact urban form designed around transit stations can reduce travel costs, wages, and housing costs by increasing accessibility, which can lead to substantial net benefits for industry categories and for lower income households. Higher income households may be net losers, since their incomes are more dependent on reduced wages, they are less willing to switch to higher density dwellings, and they are more likely to own their own home.
