If the inductive loop or the vehicle detector is bad, the detector
could put a constant call to the side street direction. This would
bring up the side street every cycle to it's max.
Call the people in charge. If they can not fix the problem, they
will make timing adjustments until the problem can be fixed. This
will still bring up the side street, so keep calling weekly. It
will help move your problem to the top of the long list. It is also
possible that the side street is programmed for recall. If the loop
has to be replaced, ask for a quadrupole loop. It will sense
bicycles and motor cycles. Denis
