Examining the L.A. Metro Rail: A Needs-based Transportation Analysis L.A. County Public Transportation Need Index
Introduction The planned expansion of the Los Angeles Metro Rail promises to provide Angelinos with access to an alternate form of public transportation. However, some critics of the L.A. Metro Rail believe that the expanding network will primarily serve tourist destinations and powerful economic hubs rather than supporting the residents most in need of access to public transportation. The goal of this research is to determine if the residents most in need of public transportation will benefit from the expansion of the L.A. Metro Rail.
Public Transportation Need Index Score Descriptions

Maximum Need No Access to a Personal Vehicle Use of Public Transportation to Work High Population Density
Household Income Below County Average
Four variables from the 2010 American Community Survey were used to create a transportation needs index. Each varviable was weighed based upon its relevance for determining a communityâ€™s need for public transportation. The resulting scores helped identify the census tracts in L.A. County most in need of access to public transportation.

The primary study area for this project consists of thirty census tracts in South L.A. The site was evaluated along with two neighborhoods near future rail line extensions (Expo Line & Crenshaw Corridor) in order to compare demographic information and selected variables.

Transportation Analysis Quarter mile buffers were placed around existing and future rail stations to identify the primary areas serviced by the Los Angeles Metro Rail. This analysis reveals that the South L.A. study area will continue to be undeserved by the growing metro network even though it will soon be surrounded by rail lines on all sides.

The South L.A. study area indicated the highest need for public transportation.

This research concludes that the Los Angeles Metro Rail does not effectively connect the residents most in need of public transportation to the greater transit network. Although residents in South L.A. indicated a maximum need for public transportation they remain outside of a reasonable walking distance from any single station. This reveals that the Los Angeles Metro Rail will remain inaccessible to the entire South L.A. neighborhood except via multi-modal transit.
