This week Metro and the city of Los Angeles Transportation Department (LADOT) began the second phase of automated bus lane enforcement. In February, on-bus camera ticketing is got started on Wilshire Boulevard and La Brea Boulevard. In March, warning tickets started on the Olive Street and Grand Avenue bus lane couplet in downtown L.A.
As of yesterday, on-bus AI cameras on Olive and Grand buses, including the Metro J Line, are issuing $293 tickets to cars parked illegally in bus lanes or at bus stops. Both the Olive and Grand bus lanes are in effect from 7 a.m. to 7 p.m. Monday through Friday.
LAist reported that the initial phase (on Wilshire and La Brea) cameras issued nearly 15,000 tickets in the first two months.
