The study of metro infill-stations in Los Angeles
(A visiting affiliate of CAUPD)
• Does the existing rail stations consistent with the distribution of high transit-dependent residents?
• Where are the best locations for infill stations to serve existing residents?
• How walkable are the existing and proposed stations?
That’s the metadata being created for the proposed infill station layer.
Transit dependent index = % No-vehicle families + % Transit use + Median Income + distance from stations
• Most Metro rail stations are consistent with the distribution of high transit-dependent residents.
• The service area is smaller in areas with lower road-density.
• New infill stations should locate in areas with high transit needs along the existing rail line.
• The locations of new infill stations should not overlapping existing service areas.
• The road-density should be planned higher around rail stations.
1. Inset Map
Included in Layout 1 & 11
Merged Metro stations Red Line, Green Line, Purple Line, Blue Line and Gold Line stations (Layout 1)
Converted the vector-based shapfiles to raster files to be used in Spatial Analysis (Layout 2, 3, 4, 14)
4. Proximity analysis
Proximity analysis to Rail Stations (Layout 5)
5. Hotspot Analysis
Analysis of high transit need used to determine appropriate locations for infill stations (Layout 6)
1/2, 4/5, 1 mile buffers (Layout 7, 10)
7. Original Data
Created a point layer for the proposed infill station (Layout 8 ) 8)
Geocoded the new layer for the infill station (Layout 9)
Satellite images (Layout 11)
Service Area Chart (Layout 12)
11. Network Analyst
Created walking service areas around existing and proposed rail stations (Layout 9)
Created metadata for the proposed infill station layer (Layout 15)
