摘要：	The purpose of the Transportation Trend Analysis and Demographic Projection Study was to analyze past population and travel trends, and project future trends, in order to support the state infrastructure and development planning process. Tasks included: Projecting population to 2025 for the state of California at the tract level, including sociodemographic variables likely to influence travel choice and opportunity; Developing a spatial database so that the Department of Transportation and its planning partners can access and manipulate the projections; Implementing and testing an empirical model of travel demand using data from urban areas in California; Combining the results of the empirical model and population projections to forecast statewide travel trends at the Census tract level in 2015 and 2025; and Explaining how the projected population changes and travel demand trends can be used to inform the planning of the state transportation system. / NOTE: Final rept. / Supplementary Notes: Sponsored by California State Dept. of Transportation, Sacramento.
