ATSPM Configuration - Signal
If unchecked, signal will still
show in Signal List. If unchecked
and IP is configured, the system
will still retrieve data.
Expand to create notes that will appear
when displaying a metric for this signal

ATSPM Configuration – Approach
Detector’s primary phase. Usually
the phase for through movement
and the protected phase for P&P
left turns.
Secondary phase for detector.
Usually 0 for through movements
and protected-only left turns.
Input the permissive phase for
P&P left turns.
Approach direction Informational text for
Phase/Direction header
Indicates the number in
Protected Phase is the
overlap number.

Detection – Advanced Count & Speed
Optional
Applies only to PCD metric:
Detector distance from stop bar
in feet. Detector actuations will
be offset to arrival at the stop
bar based on the distance and
MPH configured.
Applies only to PCD metric:
Number of seconds to offset the
detector actuations. Usually 0.
Applies only to Speed metric:
Number of seconds after start of
green to start using speed data.
Should be roughly the queue
clearance time to the detector.
Usually 15s.
Applies only to Speed metric:
Speeds below this number
(mph) will not be included in the
speed metric.

Yellow & Red Actuations
� Is green time too short? – Would increasing the split fix the problem?
� Is coordination poor? – Would more vehicles arriving on green fix this?
� Is sight distance poor? – Are there trucks or other obstructions blocking signal?
� Is law enforcement needed? – Time can be pinned down for law enforcement.

Too many force offs: identifies phases
with more than 90% force offs in at least 50
activations between 1 a.m. and 5 a.m. 33
Too many ped calls: identifies phases
with more than 200 pedestrian activations
between 1 a.m. and 5 a.m. 44
Low PCD detector count: identifies phases
with PCD detectors that have less than 100 vehicles
counted between 5 p.m. and 6 p.m. the previous day.55

Alert
Evaluation
Check for recalls
Consider whether a bandaid is necessary
Check for constant call on a detector channelToo many max
outs22
Check communication to signal
Check controller clock
Check IP address in SPM configuration
Check VIOT = NO & DB State = All Saved (Econolite MM 9-3-1 SpFn*3)
Try enabling Upload Current
Create a WO to cold start the controller
No ATSPM data11
Should the signal be in coordination?
Is a non-coordinated phase maxing out?
Skip only 2-6 pairs and dummy phases
Too many force
offs33
Check for recalls
Check for constant call on a detector channel
Too many ped
calls44
Is count channel configured correctly in SPM Config Tool?
Is ECPI Log enabled for count channel?
Is the detector working?
Is the detector communicating to the controller?
Try resetting the sensor and VERIFY with Upload Current
Note: Evaluate the VOLUME on the PCD charts, not the phase data
