Urban Spatial Structure, Employment Sub-Centers, and Passenger and Freight Travel

The impact of polycentric metropolitan development patterns on passenger traffic and freight flows is poorly understood. In major metropolitan areas nationwide, employment sub-centers are transforming from "business only" districts into multi-use locales that often have residential, office, retail, light industrial, and warehousing uses in close proximity competing for space on the same road network. In this research, the project will first identify sub-centers in metropolitan Los Angeles using the National Employment Time Series (NETS), which has the location and industry code of all business establishments in the region. The project will characterize passenger travel associated with major sub-centers using the National Household Travel Survey or the California Household Travel Survey and/or available regional travel diaries. Freight vehicle miles traveled will be estimated for sub-centers, possibly based on data from the 2007 Commodity Flow Survey (which reports shipment distances by North American Industry Classification System code) or other methods and disaggregated data on the location of business establishments in the greater Los Angeles region from the NETS. This research will allow estimates of both passenger and freight travel associated with different employment centers, providing insights into relationships between land use, industrial structure, and the use of the road and highway system by both passengers and freight.
