Accessibility, Location and Employment Center Growth
P.I. Name & Address
The purpose of this research is to examine the relationship between accessibility and the growth of employment centers in order to improve our understanding of how transportation investments influence the spatial organization of metropolitan areas. Although research on the existence of employment centers -- concentrations of employment outside the tradition downtown -- is extensive, we have little understanding of how these centers emerge and grow, and what role transportation access may play in this process. Research on employment centers is limited mainly by data availability: there is no publicly available source for reliable, highly detailed and disaggregate employment data. In this research, time series establishment level data for Californiaâ€™s four largest metropolitan areas will be used to identify employment centers and analyze relationships between center growth and transport access, including direct and indirect influence of highway and airport access.
This project extends previous research, funded in part by prior METRANS grants (e,g, project 06-16), in the following ways: 1) extends the analysis beyond the Los Angeles region; 2) uses establishment level geography, not census tract aggregates, allowing more precise measurement of centers and access measures; 3) provides detailed data on industry sector, business volume, employment, and firm births, deaths and moves; 4) uses time-series data, rather than comparisons across census years.
The relationship between transportation and urban form has become a major public policy issue. Concerns about energy consumption, global climate change, and urban sprawl have led to proposals to use transportation investments to promote more concentrated land use patterns. Results of this research will contribute to our understanding of how the economic and spatial structure of metropolitan areas change over time and how these changes may be related to highway, transit, and air networks, offering valuable guidance for future policy.
