Study of Transit Corridors Based on Goldline in LA UP206A Final Presentation Feng Zhu, Mar/19/2012
Research Purpose(1)—Midterm • Compare travel behavior changes before and after the opening of Goldline.(From 2000 to 2010) • Finding: • After the opening of GL, there was slight decrease of Auto-dependence and commuting timewithin station surrounding areas from 2000 to 2010.
Research Purpose(2)—Final • Plan Bus Transit Routes connecting critical transit nodes in Goldlineand surrounding areas, comparing service efficiency of different routes. Goldline Transit Node Main Bus Stop Bus Rapid Route
Step1:Find Nodes Step2:Calculate Transit Need Index Step3:Compare Bus Routes • Three Steps • Use Service Area Analysis to find important transit nodes along Goldline. • Use Hot Spot Analysis to calculate Transit Need Index nearby, and Geocoding main bus stops. • Use OD Cost Matrix and Closest Facility Analysis to plan Bus Rapid Routes, comparing service efficiency in Buffer area along routes.

Conclusion • After the opening of GL, there was slight decrease of Auto-dependence and commuting time within station surrounding areas from 2000 to 2010. • Three Goldline Nodes and Five Transit Need Areas need to be connected by Mass Transit, the most important is from West of LA Downtown to Union Station.
