The Los Angeles County Metropolitan Transit Authority (branded "Metro," once "MTA") was created in 1993 from a merger of the Southern California Rapid Transit District (SCRTD) and the Los Angeles County Transportation Commission.
Metro bus system operates more than 1,500 buses at peak time on 114 routes. There are 11,748 bus stops in Metro's 1,433 square mile service area.
