Study of Transit Corridors Based on Goldline in LA

Research Purpose(1)—MidtermCompare 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 time within station surrounding areas from 2000 to 2010.

Research Purpose(2)—FinalPlan Bus Transit Routes connecting critical transit nodes in Goldline and surrounding areas, comparing service efficiency of different routes.

Goldline

Transit Node Bus Rapid RouteMain Bus Stop

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.

Four Factors Influence Transit Need

Population Density

Household Income

% of Under 18 and Above 65 Years

% of No Car Family.

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.
