traffic_signal_phase_failure

In support of automated traffic signal performance measures (ATSPM), this data indicates the rate (in terms of number of cycles) at which the queue fails to clear during a specific phase. The queue is assumed not to have cleared the approach if the call on the vehicle detector for that phase never clears.
