Signal Detection Status - By Signal Intersection

Object table: signals

• There are fields that exist on this table DETECTION_STATUS, DETECTION_STATUS_DATE

• These are to have the individual detector statuses roll up to the parent (signals)

• See automated process below

Signal Detector Status - By Individual Detector

Object table: signals_detectors

Home>Detectors

• this shows the individual detectors at a signal intersection, shows the detector device status for each device

• there is a link to the Edit Detection page that is also accessible from the Signal Details page

Edit Detection page

• This page shows the various detector devices on a particular signal intersection and also has embedded form to add a new detector

• There is an + Add Event link in the Edit Detection table

  • Allows user to select a detection action on a particular device

  • will turn the status into BROKEN or OK

Automated Processes explained

There is a script detection_status_signals.py that updates the individual detector device's status and rolls it up to th parent (signal). So, if any detector devices at a specific signal ID are broken the entire Detection Status for that signal is BROKEN.

signals_detectors table

• ex. 1 of 4 detectors is BROKEN

SIGNAL ID	DEVICE STATUS	DETECTION STATUS
10	BROKEN	BROKEN
10	OK	BROKEN
10	OK	BROKEN
10	OK	BROKEN
