Equity analyses based on traditional travel demand forecast models are compromised by aggregation biases and data availability limitations. Use of the disaggregate (individual person-level) San Francisco tour- based microsimulation model made it possible to estimate benefits and impacts to different communities of concern based on individual characteristics such as gender, income, auto availability, and household structure. In this paper, the concepts and policy context of equity analysis in transportation are first presented. Identifying communities of concerns and relevant measures of transportation system performance are then outlined. The San Francisco Model structure is briefly described, and finally, the results of the equity analysis are presented.</p>
