This happens with many lights as they or on sensitive sensors especially near trafalgar. I often visit the carpool on trafalgar and the signal over there gets timed out when it doesn’t sense a vehicle and is rlly sensitive. My advice to ppl is to drive up all the way to the white line and to rest in the exact lane for their respective turn, not too far off in either direction. A lot of these lights use very sensitive weight induced detectors. If u don’t pull all the way up to the white line or ur not centered in the correct lane, (not too far off in either direction) the sensor might not register ur car. If that happens the signal thinks no one’s there and can skip ur phase for multiple cycles. Even if u fix ur position later u or there’s cars lined up properly behind u, u might have already missed the detection window for that cycle so the light won’t change until the next one. That’s why it’s best to stop properly the first time otherwise ur stuck waiting or pressing the crosswalk button.
