Giuliano and PhD students are conducting research on two related topics.  First, we have developed a conceptual framework for the freight landscape, building on standard urban economic theory.  We have tested the hypothesis that the spatial organization of population and economic activity explains freight intensity, defined as the density of truck volumes.  We use population, employment, and transportation system data from the Los Angeles region and estimate two models, one with dummy variables for combinations of population and employment density, the other with population characteristics and industry sector variables.  Preliminary results support the hypothesis, suggesting that spatial variables may serve as effective proxies for freight activity.
