  1. The Influence of Metro Rail on Travel Behavior ——A Case Study of Gold Line in LA • Opened in 2003 • 19.7miles • 21 Stations • Light Rail UP206A Midterm Presentation Feng Zhu, Feb/13/2012

  2. Background • Study Area: 86 Census Tracts which are within 0.5 miles of the Gold Line Stations. • Research Purpose: Compare travel behavior changes before and after the opening of GL.(From 2000 to 2010) • Two Variables: (1)Commuting Time. (2)% Auto Dependance(Drivealone+Carpool/Total) • Data Source: (1)U.S. Census Bureau:2000 SF3 Sample Data,2010 ACS 5-year estimates. (2)Metro Developer

  3. Skills: (1)Inset Map (2)Geoprocessing-Clip(3)Boundary sub-sets seclections-study area was derived by selecting tracts within 0.5 miles of GoldLine Stations

  4. Skills: (1)Point graduated symbol (2)Creating indices(% Autodependance was derived by drivealone+Carpool/total) • % Autodependance: 77% • Commuting Time: 30mins

  5. Skills: (1)Point graduated symbol (2)Creating indices(% Autodependance was derived by drivealone+Carpool/total) • % Autodependance: 75% • Commuting Time: 28mins

  6. Commuting Time Change(64 tracts) • <0min,30tracts; • >0min, 20tracts; • No Change,5tracts • Skills: (1)Attribute sub-sets section(ShapefileTimechange was derived by reversely selecting field of “trip time” don’t equal to Null)

  7. % Auto Dependance Change(65tracts) • <0,41tracts; • >0,24tracts. • Skills: (1)Attribute sub-sets section(ShapefileTimechange was derived by reversely selecting field of “Auto dependance” don’t equal to Null)

  8. Conclusion • After the opening of GL, there was slight decrease of Auto-dependance and commuting time within station surrounding areas from 2000 to 2010. • But whether it was caused by GL is still uncertain, because it maybe influenced by others factors, such as change of social and economic situations.(Next Step in the Finals) • Skills • Inset Map • Point graduated symbol • Creating indices • Attribute sub-sets selection • Boundary sub-sets selection • Geoprocessing
