1. UP206A Midterm Presentation Feng Zhu, Feb/13/2012 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

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

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

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
