In our ongoing map series we are examining the transportation system and structure in Los Angeles and their related factors. This series of maps move away from the transportation system and focuses on related land use and demographic factors. The data presented here demonstrate where Angelenos live and work, their rates of automobile ownership, land uses in the city, and commute travel times. While these might not be factors that appear to be intuitively link, there are connections that can be made between each of these four sets of data (and with the previous maps we have produced and those yet to come).
Land Use Designations (upper left)
Land use and transportation are intrinsically linked. The type and intensity of each land use generates varying travel demands on the transportation system. As a result, recent and planned transportation investments are typically focused around areas with greater land use intensities. At the same time the City’s General Plan Framework is a guiding policy document that directs population growth in those areas best served by transit infrastructure. Shown on this map is the Land Use designation for Los Angeles, as outlined by the City’s General Plan.
Jobs/Housing Balance (upper right)
This map shows the varying concentrations of jobs and housing within the City. Comparing the overlying roadway, busway, and railway network displays the clear link between transportation hubs and areas with a concentration of jobs and housing.
Commute Time (lower right)
This map shows the average time it takes a person to commute to work from each census tract. It provides an interesting point of comparison with the Jobs/Housing map. The largest area with higher than average commute times is found in South LA, wherein this same area on the Jobs & Housing map is shown to have a predominance of high density housing with a low density of jobs. Conversely, West Los Angeles residents have relatively shorter commute times thanks to the higher concentration of jobs nearby. But, as illustrated by the long commute times for residents in places such as Koreatown and Hollywood, that have both dense housing and a high concentration of jobs, we all aren’t fortunate enough to live near our work, even when there are a high number of jobs nearby.
Automobile Ownership (lower left)
This data shows the percentage of households in each census tract that own either one or zero automobiles. In some instances these households choose to own fewer automobiles, as is often the case in Downtown Los Angeles. However as evidenced by the strong correlation between median income and the rate of car ownership in most cases, it is a matter of economics. The census tracts shaded in red and orange show those areas of the City where households are more dependent on transit as a means of mobility. Shaded in red and orange show those areas of the City where households are more dependent on transit as a means of mobility.
The data used to create these maps comes from a variety of sources. Land use data is created and maintained by the Los Angeles Department of City Planning. Jobs, housing, commute length, and automobile data comes from variety of Census sources, including 2009 LEHD , 2009 American Community Survey, and 2010 Census.
