Phase I of the Expo Line is projected to be finished by Board approved phase II of the Expo Line that will end in Santa Monica. Draft Environmental Impact Report (DEIR) called for two alternative Phase II routes in West Los Angeles. Critics of the Expo Line often overlook the large number of transit dependent and low income households in West Los Angeles. This analysis examines the two alternatives accessibility by these households. Image Source: MTA Website -
Maps Created by Daniel Wu Data Source: MTA, U.S. Census 2000, ESRI Skills: Inset Map of Southern California and Geocoding of Proposed Stations.
Two exposition route alternatives: Right of way (ROW) alternative and Sepulveda alternative. ¼ mile buffer around proposed stations on both alternatives. Identified 21 census block groups (8 for ROW alternative and 13 for Sepulveda alternative). Maps Created by Daniel Wu Data Source: MTA,U.S. Census 2000, ESRI ROW: Census Block GroupsSepulveda: Census Block Groups Skill: Buffering of Proposed Stations.
Maps Created by Daniel Wu Data Source: MTA,U.S. Census 2000, ESRI Block group populations are larger along the Sepulveda alternative. Density (population/sq. mile) of block group is higher along the Sepulveda alternative. Skills: Attribute by Sub-set selections ( Block Group Population/Sq. Mile was derived by querying LACounty_blkgrp for Tract = (specified tract number) and Blkgrp = (specified block number), and exporting data to a new layer ). Point graduated symbol for Block Group Population. ROW: Population and DensitySepulveda: Population and Density
Maps Created by Daniel Wu Data Source: MTA,U.S. Census 2000, ESRI Skill: Aggregated attribute fields; Low Income Residents = Household Income (HHI) less than $10,000 + HHI $10,000 to $14,999 +HHI $15,000 to $19,999 + HHI $20,000 to $24,999+ HHI $25,000 to $29,999. % Low income Residents = Low Income Residents/Total Households. % of low income residents is higher in block groups along the Sepulveda alternative. % of households with no vehicles is higher along the Sepulveda alternative. ROW: Vehicles and Low-IncomeSepulveda: Vehicles and Low-Income
Maps Created by Daniel Wu Data Source: MTA,U.S. Census 2000, ESRI Public transit commute time varies along both routes. % of transit dependent households with no vehicles is higher along the Sepulveda alternative. ROW: Transit Dependency and Commute Time Skill: Creating index; % of Transit Dependent Households =.5*( Percentage of Household with no vehicles) +.5*(Percentage of workers who commute by walking, biking or public transit). Sepulveda: Transit Dependency and Commute Time
